    BACKGROUND OF THE INVENTION FIELD OF THE INVENTION
    [0001] The modalities described in the present invention refer to apparatus and methods used in the hydraulic fracturing of downhole formations. More specifically, the modalities described here refer to bottom valves used in hydraulic fracturing operations. DESCRIPTION OF RELATED TECHNIQUE
    [0002] This section, in this document, presents information about and / or derived from the technique, which can provide context or relate to the matter described in this document and / or claimed below. It presents information from previous ones, in order to facilitate a better understanding of the various aspects of the present invention. This is a discussion of the "related" technique. Such a related technique is not necessarily, also, an “earlier” technique. The related technique may or may not be prior art. The discussion in this section of this document should be read from this perspective and not as if it were recognized prior art.
    [0003] Current designs for valves used in the completion method revealed above tend to fail because cement or other debris interferes with opening the valve after the cementation process is completed. The parts of the commonly used sliding sleeve or pistons are exposed to both the flow of cement and the cement flowing between the well bore and the casing column. BRIEF SUMMARY OF THE INVENTION
    [0004] The valve, according to the invention, overcomes the difficulties described above by isolating a sliding sleeve between an external housing and an internal mandrel. A rupture disc in the internal mandrel breaks at a selected pressure. Then, the pressure will act against one end of the sliding sleeve and move the sleeve to an open position, so that the fracturing fluid will be directed against the cement lining. The sliding sleeve includes a swing ring nut to prevent the sleeve from sliding back to a closed position.
    [0005] In a first aspect, a valve comprises a housing that has an opening; a mandrel that has an opening and a passage; a sliding sleeve arranged in the housing, in which the mandrel has an opening; a rupture disc arranged in a mandrel passage; a sliding sleeve arranged between the housing and the mandrel and a spherical seat arranged in the mandrel.
    [0006] A second aspect includes a method for actuating a valve that comprises a housing that has an opening; a mandrel that has an opening and a passage; a sliding sleeve arranged between the housing and the mandrel and a spherical seat arranged in the mandrel. The method comprises: making a fluid flow through the valve; drop a sphere; seat the ball on the spherical seat and block the flow of fluid through the mandrel; flow fluid through the passage to the sliding sleeve; move the sliding sleeve axially inside the valve and expel the fluid through the housing and mandrel openings.
    [0007] In a third aspect, a valve comprises: a housing that has an opening; a mandrel arranged in the housing, in which the mandrel has an opening and a passage; a sliding sleeve arranged between the housing and the mandrel and a spherical seat arranged in the mandrel that blocks the fluid communication between the mandrel and the passage.

DETAILED DESCRIPTION OF THE INVENTION
    [00026] The illustrative embodiments of the invention are described below. For the sake of clarity, not all features of an actual deployment are described in this specification. Certainly, it will be seen that in the course of any such real modality, many specific deployment decisions need to be made to achieve specific objectives of the developers, such as compliance with system and business-related restrictions that will vary from one deployment to the next. other. In addition, it is clear that such an effort in development, even if complex and time-consuming, would be a routine job for those who have common skill in the technique with the advantage of this description.
    [00027] As shown in Figure 1, a valve embodiment 10 of the invention includes a main housing 13 and two similar end connector parts 11, 12.
    [00028] The main housing 13 is a hollow cylindrical part with threaded parts 61 at each end that receives threaded parts 18 from each end connector. The end connectors 11 and 12 can be internally or externally threaded, for connection, to the casing column. As shown in Figure 2, the main housing 13 includes one or more openings 19 that are surrounded by a circular protective cover 40. The cover 40 is made of material with high impact resistance.
    [00029] Valve 10 includes a mandrel 30 that is formed as a hollow cylindrical tube that extends between end connectors 11, 12, as shown in Figure 2. Mandrel 30 includes one or more openings 23 that extend through the wall outside of the mandrel. The mandrel 30 also has a threaded intermediate outer part 51. One or more rupture discs 41, 42 are located in the mandrel, as shown in Figure 3. The rupture discs 41, 42 are located within passages that extend between the surfaces inner and outer mandrel 30. Annular recesses 17 and 27 are provided on the outer surface of the mandrel to receive suitable seals.
    [00030] Mandrel 30 is confined between end connectors 11 and 12 when engaging a shoulder 15 on the inner surface of the end connectors. The end connectors 11 and 12 include longitudinally extending parts 18 that separate the outer housing 13 and the mandrel 30, thereby forming a chamber 36. The parts 18 have an annular recess 32 to aid a suitable seal. A sliding sleeve member 20 is located inside chamber 36 and generally has a hollow cylindrical configuration, as shown in Figure 4. Sliding sleeve member 20 includes a smaller diameter part 24 that is threaded on 66. It is also provided with indentations 43 that receive the end parts of shear pins 21. The sliding sleeve member 20 also includes annular grooves 16 and 22 that accommodate suitable annular seals.
    [00031] A locking ring retainer 25 has ratchet teeth 61 and retains a locking ring 50 that has ratchet teeth 51 on its outer surface and ratchet teeth 55 on its inner surface, as shown in Figure 9. The locking ring 50 includes an opening at 91, as shown in Figure 7, which allows it to increase in diameter as the sliding sleeve moves from the closed to the open position.
    [00032] The locking ring retainer 25 has sufficient space in the diameter, so that the threaded locking ring can engage the chuck ratchet teeth 63, without ever losing the threaded contact with the locking ring retainer. Locking ring retainer 25 is threaded 26 to engage threads 24 in the mandrel. The locking ring retainer 25 also has a plurality of holes 46 and 62n not shown, for by screws.
    [00033] In use, valve 10 can be connected to the casing column via end connectors 11, 12. One or more valves 10 can be incorporated into the casing column. After the casing column is positioned inside the well, the cement is pumped down through the casing and out of the bottom in the annular space between the well bore and the casing, as is typical in the art. After the cement flow is complete, a plug or other device is pumped down to clean the remaining cement from the liner and valve. When the plug or other device is locked or sealed in the bottom hole assembly, the pressure is increased until the rupture disc ruptures at a predetermined pressure. The fluid pressure will act on the sliding sleeve member 20 to cause the shear pins to break and then move downward or to the right, as shown in Figure 7. This movement will allow the fracturing fluid exit through opening 23 in the mandrel and openings 19 in the outer housing. The fracturing fluid, under pressure, will remove the protective cover 40 and crack the cement lining, and also fracture the foundation adjacent to the valve 10.
    [00034] Due to the fact that the sliding glove member 20 is isolated from the cement flow most of the time, the glove will have a lesser tendency to clog or to require more pressure to act.
    [00035] In the open position, the locking ring 50 engages the threads 63 to the mandrel to prevent the sleeve from moving back to the closed position.
    [00036] A breather 37 is located in the outer housing 13 to allow air to escape when the valve is fitted. The vent 37 is closed by means of a suitable plug after assembly.
    [00037] Referring now to Figure 10, a cross-sectional view of a valve in a closed position is shown, according to one embodiment of the present disclosure. The valve 100 is shown, coupled to an upper tool set 106 and a lower tool set 107. The upper tool set 106 and the lower tool set 107 can include any number of tools used in downhole operations that include , for example, packers, subsets, flow control equipment, etc. Valve 100, upper tool set 106 and lower tool set 107 are coupled via screw connections 108. In this embodiment, valve 100 includes housing 105 and mandrel 110. Housing 105 and mandrel 110 can be formed by metals known in the art, such as, for example, various types of steel.
    [00038] Housing 105 has one or more openings 111 located around valve 100. The number, location and size of openings 111 may vary depending on the requirements of a particular valve type 110. For example, in certain embodiments, openings 111 can vary from several inches to several feet in length. In addition, the geometry of the openings 111 may vary depending on the requirements of a particular operation. For example, in certain embodiments, openings 111 may be generally rectangular, while in other embodiments, openings 111 may be more round / circular in terms of geometry. In addition to the openings 111 in the housing 105, the valve 100 also includes one or more corresponding mandrel openings 112. The openings 112 of the mandrel 110 correspond, in terms of location, to the openings 111 in the housing 105 and, as such, the geometry and the size of the mandrel openings 112 may vary, as the openings 111 of housing 105 vary.
    [00039] A sliding sleeve 115 is arranged between the housing 105 and the mandrel 110. In this embodiment, a first chamber 120 is formed between the housing 105 and the mandrel 110 and is located axially above the sliding sleeve 115. Similarly, a the second chamber 125 is formed between the housing 105 and the mandrel 110 and is located under the sliding sleeve 115. The first and second chambers 120 and 125 are under atmospheric pressure when the sliding sleeve 115 is in a closed position. Because the pressure in the first and second chambers 120 and 125 is balanced, that is, both chambers are under atmospheric pressure, the sliding sleeve does not move axially within chambers 120 and 125 and, therefore, valve 100 remains in a position closed.
    [00040] A passage 130 is located axially above the sliding sleeve 115 and fluidly connects the internal diameter of the mandrel 110 to the first chamber 120. In a closed position, a rupture disc 135 can be located in the passage 130, blocking, for example, that is, a flow of fluid from the tapped hole 140 of the valve 100 in the first chamber 120. As explained above, the rupture disc 135 can be formed of a material that is intended to rupture or break at a specific pressure.
    [00041] For example, in one embodiment, rupture disc 135 may be designed to break at approximately 210.92 kgf / cm2 (3,000 PSI). In other embodiments, the rupture disc 135 can be designed to break at lower or higher pressures, such as, for example, 70.31 kgf / cm2 (1,000 PSI), 351.53 kgf / cm2 (5,000 PSI), 703 , 07 kgf / cm2 (10,000 PSI) or 1,054.6 (15,000 PSI). The pressure at which the rupture disc 135 ruptures can vary, depending on the specific design of the valve 100 and operational requirements, so that it will be readily determinable by those skilled in the art who have the advantage of this disclosure. For example, the pressure range of rupture disc 135 may vary as a result of the depth of the well, the properties of the fluid that is pumped into the well, valve size 100, etc.
    [00042] In certain embodiments, multiple rupture discs 135 can be located around the inner diameter of the mandrel 110. For example, two rupture discs 135 can be arranged at approximately 180 ° to each other. People of ordinary skill in the art will find that when lining horizontal wells, due to the relatively low side of the tool, the cement may tend to settle on the lower side of the tool. To prevent settling cement from taking time or to prevent valve 100 from acting, multiple rupture discs 135 can be included in valve 100. If one of the rupture discs 135, on a low side of the valve, 100 is covered with cement and does not may break, a second excess rupture disc 135 may be located on a high side of the tool. Due to the fact that the cement did not cover the rupture disc 135 on the high side of the valve 100, the rupture disc 135 on the high side will break under the actuation of the valve, thus allowing the valve 100 to open. In a manner that will be readily determinable by those skilled in the art who have this description at their disposal, on certain valves 100, more than two rupture discs 135 may be included. For example, three, four, five or more rupture discs 135 can be included to provide additional levels of foresight.
    [00043] The valve 100 also includes a spherical seat 145 disposed in the hollow hole 140. In this embodiment, the spherical seat 145 is coupled to the internal diameter of the mandrel 110 and is located axially below the housing and the mandrel openings 111 and 112. A spherical seat 145 is configured to receive a sphere (not shown) that can be dropped from the surface in order to act on valve 100. People of ordinary skill in the art will readily be able to see that the size of the opening 150 through spherical seat 145 can vary in order to receive a certain diameter of sphere. For example, the size of the ball diameter can vary in increments of 1 / 16a inch in operations in which multiple valves 100 are used. In order to allow multiple valves 100 to be actuated over the length of a well, the spherical seats 145 that correspond to the spheres with a smaller diameter may be arranged at a distal location more distant in the well, in relation to the surface, while spherical seats 145 corresponding to the spheres with the largest diameter can be arranged in a location close to the surface. In this way, sequentially larger spheres can be released, thus allowing multiple valves 100 to be opened.
    [00044] Referring now to Figure 11, a cross-sectional view of a valve in an open position is shown, according to the modalities of the present disclosure. The components of valve 100 correspond to those shown in Figure 10, as described above. In an open position, the sliding sleeve 115 is located axially below the housing 105 and the mandrel 110, thus allowing fluid communication between the hollow hole 140 and the annular space of the liner (not shown).
    [00045] In order to actuate valve 100 in an open position, a ball 150 is released from the surface of the well. Ball 150 is pumped into the pit until it contacts and settles against spherical seat 145, as shown. As the fluid continues to form in the hollowed hole 140, the pressure increases until a selected pressure is reached that causes the rupture disc 135 to rupture. As the rupture disc 135 ruptures, fluid flows through the passage 130 inside the first chamber 120. The pressure of fluid in the tubing forces the sliding sleeve 115 to cross axially downwards towards the second chamber 125. Then, the sliding sleeve 115 can be locked in place by engaging corresponding teeth 160 in a locking ring 155 and in a mandrel 105. Then, the locking ring 155 can keep the sliding sleeve 115 in a permanently open position, thus allowing the fluid flows directly through the housing and manhole openings 111 and 112.
    [00046] Referring to Figure 12, a flow chart of a method to act a valve is shown, according to the modalities of the present disclosure. The flowchart is presented to illustrate and clarify the valve activation discussed above. During the completion of a well, prior to production, the well is lined by pumping cement into the well. The cement is pumped to the bottom of the well through a hollow hole in the valve. The cement comes out of a coating column (not shown) inside an annular section of the well formed between the coating column and the formation. After the cementing operation is completed, a cleaning device (not shown), such as a cleaning bushing, is typically run through the casing column. The wiper bush is forced downward with a fluid flow and is designed to remove remaining cement from the inner diameter of the lining column, including along the inner diameter of the valve below, discussed above.
    [00047] The casing column can include numerous tools, such as packers that can be used to insulate sections of the well. As it is common for a well to include numerous production zones, particular production zones can be isolated by placing one or more packers below and / or above the production zone. Along the lining column between the packers, one or more valves can be arranged, thus allowing a fluid, such as a fracturing fluid, to be pumped into the pit to fracture the formation.
    [00048] In order to actuate a valve and allow the fracturing fluid to fracture the formation, the fluid is initially drained (in 200) through the valve. In this embodiment, the valve has a housing that has an opening, in which a mandrel has an opening and a passage, a sliding sleeve arranged between the housing and the manhole and a spherical seat arranged in the mandrel. In order to actuate the valve, a ball is released (in 205) from the surface and pumped at the bottom of the well. Once in the valve, the ball sits (in 210) on the spherical seat, thus blocking the flow of fluid through the mandrel. Because the fluid flow is blocked, a differential pressure is created above and below the seated sphere. The pressure increases above the seated ball until a selected pressure is reached, at which point a rupture disc breaks and the fluid flows through a passage that connects the valve's hollow hole to a first chamber.
    [00049] The fluid flows (in 215) through the passage towards the first chamber and in contact with the sliding sleeve. The sliding sleeve moves (in 220) axially downwards between the housing and the mandrel inside a second chamber. As the sliding sleeve moves (in 220) downwards, fluid communication is allowed between the hollow hole in the valve and the liner and / or the formation of the well. More specifically, the fluid leaves (at 225) the valve through the openings in the housing and in the mandrel.
    [00050] In certain embodiments, the sliding sleeve can be locked by forming an open position by engaging ratchet teeth of a sliding sleeve locking ring and corresponding chuck ratchet teeth. In alternative modes, the sliding sleeve may not be locked in place. In such an embodiment, the fluid pressure can keep the sliding sleeve in an open position.
    [00051] Referring to Figure 13, a cross-sectional view of a valve in a closed position is shown, according to the modalities of the present disclosure. Valve 300 is shown, coupled to an upper tool set 306 and a lower tool set 307. As explained above, the upper tool set 306 and the lower tool set 307 can include any number of tools used in bottom operations wellheads that include, for example, packers, subassemblies, flow control equipment, etc. Valve 300, upper tool set 306 and lower tool set 307 are coupled via screw connections 308. In this embodiment, valve 300 includes a housing 305 and a mandrel 310.
    [00052] Housing 305 has one or more openings 311 located in various locations around valve 300. In addition to openings 311 in housing 305, valve 300 also includes one or more corresponding chuck openings 312. Chuck openings 312 310 correspond in location to housing openings 311 305 and, as such, the geometry and size of mandrel openings 312 may vary, as housing openings 311 305 vary.
    [00053] A sliding sleeve 315 is arranged between housing 305 and mandrel 310. In this embodiment, a first chamber 320 is formed between housing 305 and mandrel 310 and is located axially above the slide sleeve 315. Similarly, a second chamber 325 is formed between housing 305 and mandrel 310 and is located under sliding sleeve 315. The first and second chambers 320 and 325 are at atmospheric pressure when sliding sleeve 315 is in a closed position. Because the pressure in the first and second chambers 320 and 325 is balanced, that is, both chambers are under atmospheric pressure, the sliding sleeve does not move axially within chambers 320 and 325 and valve 300 then remains in a closed position .
    [00054] A passage 330 is located axially above the sliding sleeve 315 and fluidly connects the inner diameter of the mandrel 310 to the first chamber 320. The valve 300 also includes a spherical seat 345 disposed in the hollow hole 340. The spherical seat 345 is located above the openings 311 and 312 and is positioned to prevent fluid communication between the drilled hole 340 and the first chamber 320. The spherical seat 345 is connected to the chuck 310 through one or more shear pins 365. Additionally, one or more seals 370 can be arranged between the spherical seat 345 and the mandrel 310 above and below the passage 330, thus effectively isolating the passage 330 from the hollow hole 340. Because the passage 330 is isolated from the hollow hole 340, the pressure balanced in the first and second chambers 320 and 325 can be maintained.
    [00055] Referring now to Figure 14, a cross-sectional view of the valve of Figure 13 is shown in an open position, according to the modalities of the present disclosure. The valve components 300 correspond to those shown in Figure 13, as described above. In an open position, the sliding sleeve 315 is located axially below the housing and chuck openings 311 and 312, thus allowing fluid communication between the drilled hole 340 and the liner (not shown).
    [00056] In order to actuate valve 300 in an open position, a ball 350 is released from the surface of the well. Ball 350 is pumped into the pit until it contacts and settles on spherical seat 345. As the fluid continues to be pumped into the hollow hole 340, the pressure increases until a selected pressure is reached, which causes the 360 shear pins break. The breaking of shear pins 360 causes the spherical seat 345 to move axially within the hollowed hole 340 forming a final open position. As the spherical seat 345 moves, the fluid flows through the passage 330 inside the first chamber 320. The pressure of fluid in the tubing forces the sliding sleeve 315 to cross axially downwards towards the second chamber 325. Then, the sliding sleeve 315 can be locked in place by engaging corresponding teeth 360 on locking ring 355 and mandrel 305. Then, locking ring 355 can keep sliding sleeve 315 in a permanently open position, thus allowing all the fluid flows through the housing and the mandrel openings 311 and 312.
    [00057] In certain embodiments, a rupture disc (not shown) may be arranged at passage 330. In such an embodiment, the rupture disc can serve as an additional check to prevent premature actuation of valve 300. Therefore, even if the seat spherical 345 move prematurely, valve 300 would not open until the selected increased pressure has been reached.
    [00058] Referring to Figure 15, a flow chart of a method for actuating a valve of Figures 13 and 14 is shown, according to the modalities of the present disclosure. The flowchart is presented to further clarify the performance of the valve discussed above.
    [00059] In order to actuate a valve and allow the fracturing fluid to fracture the formation, the fluid is initially drained by 400 through the valve. In this embodiment, the valve has a housing that has an opening, in which a mandrel has an opening and a passage, a sliding sleeve arranged between the housing and the mandrel and a spherical seat arranged in the mandrel. In order to actuate the valve, a ball is released (in 405) from the surface and pumped at the bottom of the well. Once in the valve, the ball settles (in 410) inside the spherical seat, thus blocking the flow of fluid through the mandrel. Because the fluid flow is blocked, pressure is applied to the spherical seat, breaking the shear pins that hold the spherical seat in place and causing the spherical seat to move (in 415) axially downward.
    [00060] The fluid flows (in 420) through the passage in a first chamber and in contact with the sliding sleeve. The sliding sleeve moves (in 425) axially downwards between the housing and the mandrel inside a second chamber. As the sliding sleeve moves (in 425) downwards, fluid communication is allowed between the hollow hole in the valve and the liner and / or the formation of the well.
    [00061] Advantageously, the modalities of the present disclosure can provide valves used in hydraulic fracturing operations that open completely, thus allowing for more effective fracturing operations. Advantageously, the modalities of the present disclosure can also feature valves with accessory systems to prevent premature actuation of the downhole valve.
    [00062] Although the present disclosure has been described with respect to a limited number of modalities, those skilled in the art with the benefit of this description, will appreciate that other modalities can be designed, as long as they do not deviate from the scope of the disclosure as described herein. . Consequently, the scope of the disclosure should be limited to the appended claims only.
