Description

Vibration-resistant ball bearings suitable for compressed gas energy storage injection and production operations Technical Field

[0001] This invention relates to the field of compressed gas storage well completion tools, and in particular to an anti-vibration ball seat suitable for compressed gas storage injection and production operations. Background Technology

[0002] Utilizing renewable energy sources such as solar and wind power for electricity generation is a crucial component of current clean energy development and utilization. However, solar and wind power generation is highly susceptible to natural conditions and exhibits significant fluctuations, and actual electricity consumption at the user end also experiences strong volatility. Energy storage technology is a vital means to address the contradiction between the "peak-heavy, valley-light" nature of electricity demand and the "valley-heavy, valley-light" nature of power supply. For example, compressed air energy storage, a high-capacity, high-efficiency energy storage technology developed in recent years, has become a research hotspot in the energy storage field.

[0003] In the construction of compressed air energy storage projects, large-diameter wellbores are generally used to ensure that the gas flow rate of a single injection / production cycle meets the requirements for energy storage and release, while minimizing the number of wells drilled and reducing overall costs. Compressed gas energy storage features high injection / production frequency (multiple times a day) and large injection / production volume (25–35 × 10⁻⁶ m³ / h). 4 m 3 The characteristics of the high-speed fluid ( / h) mean that the high-speed fluid under this condition can easily cause vibration of the injection and production tubing, thus affecting the safety and lifespan of the tubing. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-vibration ball seat suitable for compressed gas energy storage injection and production. It utilizes the setting pressure to achieve rigid alignment, which can significantly eliminate or alleviate the vibration caused by high-frequency, high-flow-rate injection and production of compressed gas energy.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Vibration-resistant ball mounts suitable for compressed gas energy storage injection and production operations include:

[0007] A central cylinder, wherein a pressure transmission hole is provided on the central cylinder;

[0008] A sliding piston is sleeved on the outside of the central cylinder. A first annular space, which is closed at the top and bottom, is provided between the sliding piston and the central cylinder. The first annular space is connected to the pressure transmission hole. The sliding piston can move along the axial direction of the central cylinder under the action of external force.

[0009] A sleeve is fitted onto the outside of the central cylinder and is located below the sliding piston. A second annular cavity with an upper opening is provided between the sleeve and the central cylinder. The sleeve has multiple straightening holes along its circumference, and each straightening hole is fitted with a movable straightening ball. The sliding piston can abut against the straightening ball through the opening of the second annular cavity under the action of external force, so that the straightening ball protrudes outward from the sleeve.

[0010] A setting assembly is connected to the lower end of the central cylinder to set the central cylinder.

[0011] Preferably, a thrust cylinder is provided between the sleeve and the sliding piston. The thrust cylinder is sleeved on the outside of the central cylinder. The upper end of the thrust cylinder is connected to the sliding piston, and the lower end of the thrust cylinder can extend into the second annulus through the opening to abut against the centering ball.

[0012] Preferably, the lower end of the thrust cylinder is provided with an inclined surface so that the inclined surface abuts against the straightening ball.

[0013] Preferably, shear pins are provided between the upper end of the thrust cylinder and the sleeve, and between the lower end of the central cylinder and the sleeve.

[0014] Preferably, a limiting component is provided between the end of the thrust cylinder away from the centering ball and the center cylinder, the limiting component being able to restrict the thrust cylinder from moving away from the centering ball.

[0015] Preferably, the limiting component includes a locking ring, which is sleeved on the central cylinder. The locking ring and the central cylinder are provided with mutually cooperating anti-reverse teeth. The upper end of the locking ring abuts against the sliding piston, and the lower end of the locking ring abuts against the thrust cylinder.

[0016] Preferably, the lower end of the locking ring is located between the central cylinder and the thrust cylinder; the limiting component also includes a retaining ring, which is sleeved on the central cylinder, with its upper end abutting against the sliding piston, and the inner wall of the retaining ring is provided with abutting surface that cooperates with the locking ring.

[0017] Preferably, the setting assembly includes an adjusting section disposed at the lower end of the central cylinder. A ball seat is disposed within the adjusting section, and the ball seat has a through cavity to restrict the setting ball. A locking assembly is disposed between the ball seat and the adjusting section, and the locking assembly has a locked state and an unlocked state. When in the locked state, the ball seat is connected to the adjusting section; when in the unlocked state, the ball seat is disengaged from the adjusting section.

[0018] Preferably, the through cavity includes a first cavity and a second cavity, the first cavity being located above the second cavity, and the minimum through size of the first cavity being greater than the minimum through size of the second cavity.

[0019] Preferably, the locking assembly includes a ball seat sleeve and a connector. The ball seat sleeve is located within the adjusting section, and the inner wall of the adjusting section has a slot. The ball seat sleeve has a mounting hole corresponding to the slot. The connector is inserted into the mounting hole and passes through the slot to connect the ball seat sleeve and the adjusting section. The connector can disengage from the slot under external force. A limiting platform for limiting the ball seat is provided inside the ball seat sleeve, and the limiting platform is located below the mounting hole.

[0020] The beneficial effects of this invention are:

[0021] During setting, the pressure inside the central cylinder increases, which is then transmitted to the first annulus through the pressure transmission hole. This pushes the sliding piston downward, causing it to move downward to press against the centering ball located in the centering hole. The centering ball then protrudes outward from the sleeve, and through the rigid contact between the centering ball and the external well casing, a rigid centering effect is achieved. This can eliminate or significantly alleviate the vibration caused by high-frequency, high-flow-rate injection and production of compressed gas energy storage. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] As shown in Figures 1 to 4, the present invention provides an anti-vibration ball seat suitable for compressed gas energy storage injection and production operations. It includes a central cylinder 1, a sliding piston 2, a sleeve 3, and a setting assembly 5. The central cylinder 1 is provided with a pressure transmission hole 11. The sliding piston 2 is sleeved on the outside of the central cylinder 1, and a first annular space 12, which is closed vertically, is provided between the sliding piston 2 and the central cylinder 1. The first annular space 12 communicates with the pressure transmission hole 11, and the sliding piston 2 can move axially along the central cylinder 1 under external force. The sleeve 3 is sleeved on the outside of the central cylinder 1, and is located below the sliding piston 2. A second annular space 31, with an open upper end, is provided between the sleeve 3 and the central cylinder 1. The sleeve 3 has multiple centering holes along its circumference, and each centering hole is fitted with a movable centering ball 4. The sliding piston 2 can abut against the centering ball 4 through the opening of the second annular space 31 under external force, causing the centering ball 4 to protrude outward from the sleeve 3. The setting assembly 5 is connected to the lower end of the central cylinder 1 to set the central cylinder 1.

[0033] With the above structure, when the setting is performed, the pressure inside the central cylinder 1 increases, which is then transmitted to the first annulus 12 through the pressure transmission hole 11. This pushes the sliding piston 2 downward to push against the centering ball 4 located in the centering hole, causing the centering ball 4 to protrude outward from the sleeve 3. The centering ball 4 makes rigid contact with the external well casing 20, thereby achieving rigid centering. This can eliminate or significantly alleviate the vibration caused by high-frequency, high-flow-rate injection and production of compressed gas energy storage.

[0034] In some embodiments, an upper connector 10 is provided at the upper end of the central cylinder 1. The upper connector 10 can be screwed to the central cylinder 1, thereby connecting the central cylinder 1 to the injection / production tubing string for lowering downhole or raising to the surface. In the current embodiment, the upper end of the sliding piston 2 can be limited and abutted against either the central cylinder 1 or the upper connector 10. The sliding piston 2 has a large-diameter section and a small-diameter section, with the large-diameter section located above the small-diameter section. The large-diameter section and the small-diameter section form abutment platform, and the first annulus 12 is located above the abutment platform. Thus, when the internal pressure is transmitted to the abutment platform, the sliding piston 2 can be pushed downward by the pressure of the abutment platform. In this embodiment, sealing rings are provided between the sliding piston 2 and the central cylinder 1, and between the sliding piston 2 and the upper connector 10. The sealing rings are located on the upper and lower sides of the first annulus 12 to prevent unintended pressure leakage. In the current embodiment, a shear pin 7 is provided between the sliding piston 2 and the upper connector 10 to prevent the sliding piston 2 from moving downward unexpectedly.

[0035] As shown in Figures 1 and 2, in some embodiments, a thrust cylinder 6 is provided between the sleeve 3 and the sliding piston 2. The thrust cylinder 6 is sleeved on the outside of the central cylinder 1, and the upper end of the thrust cylinder 6 is connected to the sliding piston 2. The specific connection method is not limited and can be, but is not limited to, a screw connection. The lower end of the thrust cylinder 6 extends into the sleeve 3 through the upper opening of the second annular cavity 31, so that the lower end of the thrust cylinder 6 is located above the centering ball 4. When the sliding piston 2 moves downward, it pushes the thrust cylinder 6 downward, thereby causing the thrust cylinder 6 to be embedded between the centering ball 4 and the central cylinder 1, so as to push against the centering ball 4, causing the centering ball 4 to protrude from the centering hole. In the current embodiment, in order to prevent the thrust cylinder 6 from moving unintentionally, the thrust cylinder 6 and the sleeve 3 are connected by a shear pin 7. As the thrust of the sliding piston 2 gradually increases, it can shear the shear pin 7 between the thrust cylinder 6 and the sleeve 3, so that the thrust cylinder 6 moves downward.

[0036] In some embodiments, the lower end of the thrust cylinder 6 has an inclined surface, which makes it easier for the thrust cylinder 6 to extend between the centering ball 4 and the central cylinder 1, and makes it easier to push the centering ball 4 outward.

[0037] In some embodiments, the centering holes are evenly spaced circumferentially to ensure uniform contact and further reduce the likelihood of swaying. It is understood that the size of the centering ball 4 is not larger than the size of the centering hole, thus preventing the centering ball 4 from being pushed out of the centering hole by the thrust cylinder 6. It should be noted that before the thrust cylinder 6 contacts the centering ball 4, the centering ball 4 does not protrude from the centering hole to ensure it can be lowered normally into the well and avoid interference.

[0038] As shown in Figures 1 and 2, in some embodiments, after the straightening ball 4 completes rigid straightening and the setting assembly 5 releases the setting, the pressure relief of the central cylinder 1 causes the connected sliding piston 2 to also depressurize. At this time, the reverse force exerted by the straightening ball 4 on the thrust cylinder 6 causes the thrust cylinder 6 to retract. Based on the above situation, a limiting assembly 8 is provided between the end of the thrust cylinder 6 away from the straightening ball 4 and the central cylinder 1 to limit the thrust cylinder 6 from moving away from the straightening ball 4, thereby preventing the loss of rigid straightening function under unforeseen circumstances. Specifically, the limiting assembly 8 includes a locking ring 81, which is sleeved on the outside of the central cylinder 1 and located between the central cylinder 1 and the thrust cylinder 6. The locking ring 81 and the central cylinder 1 are provided with mutually cooperating anti-retraction teeth. It should be noted that the central cylinder 1 is provided with forward teeth, and the locking ring 81 is provided with reverse teeth. The upper end of the locking ring 81 abuts against the sliding piston 2, and the lower end of the locking ring 81 abuts against the thrust cylinder 6. In other words, when the sliding piston 2 pushes the locking ring 81, the locking ring 81 can move downward through the anti-reverse teeth. However, when the pressure is released and the thrust cylinder 6 acts on the locking ring 81, the reverse teeth and forward teeth will clash with each other, and it cannot move upward through the anti-reverse teeth.

[0039] In the current embodiment, the locking ring 81 is C-shaped, which facilitates its installation onto the central cylinder 1 and avoids interference from the structure of the anti-retraction teeth. Due to this C-shaped structure, when the sliding piston 2 above the locking ring 81 and the thrust cylinder 6 below it apply force, the locking ring 81 is prone to outward deformation, potentially causing it to detach. To avoid this problem, the lower end of the locking ring 81 is located between the central cylinder 1 and the thrust cylinder 6, thus limiting the outward expansion of the locking ring 81 through the thrust cylinder 6. Furthermore, a mating abutment surface is provided between the locking ring 81 and the thrust cylinder 6, with the abutment surface on the thrust cylinder 6 facing the central cylinder 1, further restricting the locking ring 81. In addition, the limiting component 8 also includes a retaining ring 82, which is sleeved on the central cylinder 1. The upper end of the retaining ring 82 abuts against the sliding piston 2, and the lower end of the retaining ring 82 abuts against the locking ring 81. This allows for connection via the retaining ring 82, avoiding the need for irregularly shaped parts, facilitating processing, and simplifying installation. Furthermore, the inner side of the retaining ring 82 and the outer side of the locking ring 81 are also provided with abutting surfaces of the aforementioned type. The abutting surface of the retaining ring 82 faces the central cylinder 1, and the retaining ring 82 abuts against the locking ring 81 in the direction of its abutting surface towards the central cylinder 1, further limiting the outward expansion of the locking ring 81.

[0040] As shown in Figure 1, in some embodiments, a shear pin 7 is also provided between the lower ends of the central cylinder 1 and the sleeve 3. When the shear pin 7 between the central cylinder 1 and the sleeve 3 breaks, the central cylinder 1 and the sleeve 3 can move relative to each other. That is, during the recovery process, that is, during the process of lifting the central cylinder 1, the centralizing ball 4 is pressed against the outer well casing 20, and the two restrict the upward movement of the sleeve 3 under the action of friction. When the lifting force is increased, the shear pin 7 provided between the lower ends of the central cylinder 1 and the sleeve 3 will be cut off, and the sleeve 3 and the centralizing ball 4 will move downward relative to the central cylinder 1 at the same time. At this time, the thrust cylinder 6 will disengage from the centralizing ball 4, and the centralizing ball 4 will retract and disengage from the well casing 20, releasing the rigid centralization, and then the lifting recovery can continue.

[0041] As shown in Figures 1 and 3, in some embodiments, the setting assembly 5 includes an adjusting section 51 screwed to the lower end of the central cylinder 1. The setting assembly 5 also includes a ball seat housing 53 screwed to the adjusting section 51. A ball seat 54 is provided inside the ball seat housing 53, and the ball seat 54 has a through cavity that can accommodate the setting ball 52 to achieve setting. In the current embodiment, the through cavity is divided into a first cavity and a second cavity arranged vertically. The first cavity is located above the second cavity, and the minimum passage size of the first cavity is greater than that of the second cavity. Therefore, when the setting ball 52 is thrown into the second cavity for setting, if the setting ball 52 fails to set properly or fails to set properly in the second cavity, a larger spare ball can be thrown into the first cavity for setting again, thus providing a certain degree of tolerance. For example, to ensure stable setting, the first cavity and the second cavity are funnel-shaped.

[0042] To enable unsealing after setting, a locking component 9 is provided between the ball seat housing 53 and the ball seat 54. The locking component 9 has a locked state and an unlocked state. When it is in the locked state, the ball seat 54 is connected to the ball seat housing 53; when it is in the unlocked state, the ball seat 54 is disengaged from the ball seat housing 53, so as to enable unsealing and pressure relief.

[0043] Specifically, the locking assembly 9 includes a ball seat sleeve 91, which is disposed inside the ball seat housing 53 and connected to the ball seat housing 53 by a sleeve pin. When the sleeve pin breaks, the ball seat sleeve 91 can disengage from the adjusting section 51 and the ball seat housing 53 under the action of external force. In addition, the adjusting section 51 is provided with a slot, and the ball seat sleeve 91 has a mounting hole on its cylindrical wall, which is opposite to the slot. The connector 92 is inserted into the mounting hole and the slot to connect the ball seat sleeve 91 and the adjusting section 51. In this embodiment, the slot wall is an inclined surface, and the connector 92 uses a pin block. Thus, when an external force pushes the ball seat sleeve 91 down, the pin block can disengage from the slot and slide inward along the mounting hole.

[0044] In the current embodiment, the ball seat sleeve 91 is provided with a limiting platform for limiting the ball seat 54. The limiting platform is located below the mounting hole, thereby limiting the downward movement of the ball seat 54. Specifically, a retaining ring 93 is also provided inside the ball seat sleeve 91. The retaining ring 91 forms the aforementioned limiting platform. The retaining ring 93 is screwed to the lower end of the ball seat sleeve 91. The upper end face of the retaining ring 93 and the ball seat sleeve 91 form a limiting platform surface. The ball seat 54 is disposed inside the retaining ring 93, and the ball seat 54 and the retaining ring 93 are connected by a ball seat shear pin 94. The upper end of the ball seat 54 is provided with a protruding limiting part 55, so that the retaining ring 93 can block the downward movement of the ball seat 54. When the limiting part 55 abuts against the retaining ring 93, the connecting member 92 disengages from the adjusting section 51.

[0045] In other words, after the setting ball 52 sets on the ball seat 54, by increasing the pressure inside the central cylinder 1, the setting ball 52 pushes against the ball seat 54 to cut off the ball seat shear pin 94 between the ball seat 54 and the retaining ring 93. Then, by increasing the pressure, the ball seat 54 moves down, and the limiting part 55 pushes against the retaining ring 93. During the movement of the ball seat 54, the ball seat sleeve 91 is exposed through the mounting hole. When the pressure continues to increase, since the retaining ring 93 is screwed to the ball seat sleeve 91, the ball seat sleeve 91 is pushed down, thereby applying force to the connecting member 92. Since the groove wall of the slot is an inclined surface, the connecting member 92 retracts inward into the ball seat sleeve 91. Then, by continuing to increase the pressure, the sleeve pin between the ball seat sleeve 91 and the ball seat outer shell 53 can be cut off, thereby causing the ball seat sleeve 91 and the ball seat 54 to disengage from the adjusting short section 51 to achieve pressure relief. Then, the entire unit can be recovered simply by lifting the central cylinder 1.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
