Description

Technical Field

[0001] This utility model belongs to the technical field of cryogenic valve replacement at the wellhead of a gas production tree, and in particular relates to a temporary plugging agent injection device for cryogenic valve replacement at the wellhead of a gas production tree. Background Technology

[0002] Temporary plugging agents play a crucial role in the refrigeration valve replacement operation at the wellhead of the gas production tree. Their main purpose is to temporarily seal the wellhead during the valve replacement process to prevent natural gas leakage. On the one hand, the temporary plugging agent can effectively isolate the pressure inside the well, preventing the sudden ejection of natural gas during valve replacement and ensuring the safety of on-site personnel. On the other hand, it can maintain a relatively stable pressure environment inside the well, facilitating the smooth valve replacement operation by construction personnel and reducing the potential damage to wellhead equipment and other related facilities caused by pressure fluctuations.

[0003] Temporary plugging agents typically consist of multiple components, including solid particles, liquid solvents, and other additives. Before injection into the wellhead, these components need to be thoroughly and evenly mixed through stirring. However, traditional stirring methods are relatively simple and the stirring effect is not ideal, making it difficult for the solid particles in the temporary plugging agent to be evenly dispersed in the liquid. During the injection process, local concentrations that are too high or too low can easily occur. If the concentration is too high, it may cause blockage of the injection pipeline, preventing the temporary plugging agent from being successfully injected into the wellhead. If the concentration is too low, it will affect the temporary plugging effect and fail to effectively seal the wellhead, significantly reducing the overall quality and performance stability of the temporary plugging agent. To address this, a temporary plugging agent injection device for cryogenic valve replacement at the gas production tree wellhead is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a temporary plugging agent injection device for cryogenic valve replacement at the wellhead of a gas production tree well. By incorporating a stirring assembly, specifically, a motor drives two stirring blades to revolve via a limiting frame. Simultaneously, the movement of bevel gear two, through the action of bevel gear one, causes the stirring blades to rotate. During the rotation of the stirring blades, the temporary plugging agent is stirred. This stirring, achieved through the rotation and revolution of the stirring blades, ensures a uniform distribution of the chemical components in the temporary plugging agent, preventing localized high or low concentrations. This solves the problems of traditional stirring methods, which are relatively simple and have unsatisfactory stirring effects, making it difficult for solid particles in the temporary plugging agent to be evenly dispersed in the liquid. This leads to localized high or low concentrations during injection. High concentrations may cause blockage of the injection pipeline, preventing the temporary plugging agent from being successfully injected into the wellhead, while low concentrations will affect the temporary plugging effect and fail to effectively seal the wellhead, significantly reducing the overall quality and performance stability of the temporary plugging agent.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a temporary plugging agent injection device for cryogenic valve replacement at the wellhead of a gas production tree well.

[0014] Furthermore, the injection unit includes an adjustment component, which is located on the right side of the storage tank, and is used to precisely adjust the delivery flow rate of the temporary plugging agent;

[0015] An output component, which is mounted on the right side of the regulating component, provides power output for the output of the temporary plugging agent;

[0016] Among them, by adjusting the output flow rate of the temporary plugging agent through the adjustment component, it is possible to ensure that the injected temporary plugging agent just meets the requirements of sealing the space around the wellhead and preventing gas leakage.

[0017] Furthermore, the drive assembly includes a motor, the bottom of which is welded to the top of the storage tank. The output end of the motor bottom is connected to a rotating shaft via a coupling. A fixed rod is rotatably connected to the bottom of the rotating shaft. The end of the fixed rod away from the rotating shaft is welded to the bottom of the inner wall of the storage tank. A bevel gear one is welded to the outer surface of the fixed rod.

[0020] The stirring blades are two in number, and the outer surfaces of the two rotating rods are rotatably connected to the left and right sides inside the limiting frame. The first bevel gear and the two second bevel gears are all located inside the limiting frame.

[0021] Furthermore, the cleaning assembly includes a connecting rod, the inside of which is welded to the top of the outer surface of the rotating shaft, and scrapers are installed on the left and right sides of the bottom of the connecting rod;

[0022] The two scrapers, with their sides facing away from each other, contact the inner wall of the storage tank.

[0023] Furthermore, the adjustment component includes a support frame, a handwheel is provided on the top of the support frame, a worm gear is rotatably connected inside the support frame, a worm wheel is meshed with the outer surface of the worm gear, a rotating rod is welded inside the worm wheel, a rotating impeller is welded to the outer surface of the rotating rod, a fixed impeller is contacted on the side of the rotating impeller away from the worm wheel, and a conical block is connected to the inner ring of the fixed impeller.

[0027] This utility model has the following beneficial effects:

[0028] This invention incorporates a stirring assembly. Specifically, a motor drives two stirring blades to revolve via a limiting frame. Simultaneously, the movement of the second bevel gear, through the action of the first bevel gear, causes the stirring blades to rotate. During the rotation of the stirring blades, the temporary plugging agent is stirred. Through the rotation and revolution of the stirring blades, the chemical components in the temporary plugging agent are evenly distributed, preventing local concentrations from being too high or too low. Furthermore, for easily agglomerated particulate components, stirring can break them up, allowing them to mix better with other components, thus improving the overall quality and performance stability of the temporary plugging agent.

[0029] This invention features a design where rotating the handwheel clockwise drives a worm gear to rotate, which in turn drives a rotating impeller via a rotating rod. During this rotation, the impeller overlaps with and misaligns with the fixed impeller, thus regulating the flow rate of the temporary plugging agent. Precise adjustment of the flow rate ensures that the injected agent precisely meets the requirements for sealing the space around the wellhead and preventing gas leakage. Excessive use of the temporary plugging agent can lead to difficulties in subsequent valve replacement operations and may even damage wellhead facilities. Conversely, insufficient use will fail to achieve effective temporary plugging and may result in gas leakage safety hazards. Precise quantity control avoids these problems and improves the temporary plugging effect to meet operational standards.

[0041] Mixing unit 2, installed inside storage tank 113, is used to mix and stir the temporary plugging agent; and

[0042] Injection section 3 is installed on the right side of storage tank 113. Injection section 3 is used to deliver temporary plugging agent inside storage tank 113.

[0043] The device can be moved by the four wheels 11 at the bottom of the mobile frame 1, which improves the convenience and flexibility of the device.

[0044] The mixing section 2 includes a drive assembly 21, which is mounted on top of the storage tank 113 and provides power output for mixing and stirring the temporary blockage agent.

[0045] The stirring assembly 22 is installed at the bottom of the drive assembly 21, and the drive assembly 21 drives the stirring assembly 22 to stir and mix the temporary plugging agent; and

[0046] Cleaning component 23 is installed inside storage tank 113. Cleaning component 23 is also driven by drive component 21. Cleaning component 23 is used to clean the temporary blockage agent attached to the inner wall of storage tank 113.

[0047] The drive component 21 extends into the storage tank 113 and is connected to the stirring component 22. The stirring component 22 mixes and stirs the temporary plugging agent, which greatly improves the performance of the temporary plugging agent.

[0048] The injection unit 3 includes an adjustment component 31, which is located on the right side of the storage tank 113. The adjustment component 31 is used to precisely adjust the delivery flow rate of the temporary plugging agent.

[0049] Output component 32 is installed on the right side of adjustment component 31, and output component 32 provides power output for outputting temporary plugging agent;

[0050] Among them, by adjusting the output flow rate of the temporary plugging agent through the adjustment component 31, it is possible to improve the injected temporary plugging agent to just meet the requirements of sealing the space around the wellhead and preventing gas leakage.

[0051] The drive assembly 21 includes a motor 211. The bottom of the motor 211 is welded to the top of the storage tank 113. The bottom output end of the motor 211 is connected to a rotating shaft 212 via a coupling. A fixed rod 213 is rotatably connected to the bottom of the rotating shaft 212. The end of the fixed rod 213 away from the rotating shaft 212 is welded to the bottom of the inner wall of the storage tank 113. A bevel gear 214 is welded to the outer surface of the fixed rod 213. Two bevel gears 215 are meshed on the outer surface of the bevel gear 214.

[0052] The outer surface of the rotating shaft 212 is rotatably connected to the top of the inside of the storage tank 113, and the rotating shaft 212 passes through the storage tank 113 and extends into the interior.

[0053] The stirring assembly 22 includes a stirring blade 221, a rotating rod 222 welded inside the stirring blade 221, and a limiting frame 223 welded to the bottom of the outer surface of the rotating shaft 212. The bottom of the inner surface of the limiting frame 223 is rotatably connected to the bottom of the outer surface of the fixed rod 213.

[0054] The device includes two stirring blades 221. The outer surfaces of the two rotating rods 222 are rotatably connected to the left and right sides of the limiting frame 223. The first bevel gear 214 and the two second bevel gears 215 are both located inside the limiting frame 223. The starting motor 211 drives the two stirring blades 221 to revolve through the limiting frame 223. At the same time, the movement of the second bevel gear 215, through the action of the first bevel gear 214, drives the stirring blades 221 to rotate. During the rotation of the stirring blades 221, the temporary plugging agent is stirred. The stirring of the temporary plugging agent by the rotation and revolution of the stirring blades 221 ensures that the chemical components in the temporary plugging agent are evenly distributed, avoiding local concentrations that are too high or too low. At the same time, for particulate components that are prone to agglomeration, stirring can break them up, allowing them to mix better with other components, thereby improving the overall quality and performance stability of the temporary plugging agent.

[0055] The cleaning assembly 23 includes a connecting rod 232, the inside of which is welded to the top of the outer surface of the rotating shaft 212, and scrapers 231 are installed on the left and right sides of the bottom of the connecting rod 232.

[0057] The adjustment assembly 31 includes a support frame 312, a handwheel 311 is provided on the top of the support frame 312, a worm gear 313 is rotatably connected inside the support frame 312, a worm wheel 314 is meshed with the outer surface of the worm gear 313, a rotating rod 316 is welded inside the worm wheel 314, a rotating impeller 317 is welded to the outer surface of the rotating rod 316, a fixed impeller 319 is contacted on the side of the rotating impeller 317 away from the worm wheel 314, and a conical block 318 is connected to the inner ring of the fixed impeller 319.

[0058] The worm gear 313 passes through the support frame 312 and extends to the top. The handwheel 311 is welded to the outer surface of the worm gear 313. Rotating the handwheel 311 clockwise drives the worm wheel 314 to rotate through the worm gear 313. During the rotation of the worm wheel 314, the rotating impeller 317 is driven to rotate through the rotating rod 316. During the rotation of the rotating impeller 317, it overlaps and misaligns with the fixed impeller 319, thereby adjusting the flow rate of the temporary plugging agent. By precisely adjusting the flow rate of the temporary plugging agent, the injected temporary plugging agent can be just enough to meet the requirements of sealing the space around the wellhead and preventing gas leakage. If too much temporary plugging agent is used, it may cause difficulties in subsequent valve replacement operations and may even damage the wellhead facilities. If too little is used, it will not achieve the purpose of effective temporary plugging and will cause gas leakage safety hazards. By precisely controlling the amount, these problems can be avoided and the temporary plugging effect can be improved to meet the operation standards.

[0059] The output component 32 includes a pump body 322, a fixed base 323 is installed at the bottom of the pump body 322, the side of the fixed base 323 away from the pump body 322 is welded to the top of the mobile frame 1, the water outlet end of the pump body 322 is connected to an output pipe 321, the water inlet end of the pump body 322 is connected to a connecting pipe 324, and the end of the connecting pipe 324 away from the pump body 322 is connected to the water outlet on the right side of the storage tank 113.

[0060] Among them, the inner wall of the support frame 312 is welded to the outer ring of the connecting pipe 324, and the outer ring of the fixed impeller 319 is welded to the inner wall of the connecting pipe 324.

[0061] A specific application of this embodiment is as follows: In use, the temporary plugging agent is first added into the storage tank 113 through the inlet 114. Then, the motor 211 is started to drive the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it drives the limiting frame 223 to rotate. During the rotation of the limiting frame 223, it drives the two stirring blades 221 to revolve via two rotating rods 222. During the revolve of the stirring blades 221, the temporary plugging agent is stirred. Simultaneously, when the limiting frame 223 rotates, it rotates on the outer surface of the fixed rod 213. When the two rotating rods 222 revolve, they drive the two bevel gears 215 to move. During the movement of the bevel gears 215, they rotate on their own axis through the action of the bevel gears 214. During the rotation of the bevel gears 214, they drive the stirring blades 221 to rotate via the rotating rods 222. Simultaneously, the stirring blades 221... During the rotation of the rotating shaft 212, the temporary plugging agent is stirred. The stirring blade 221 stirs the temporary plugging agent through its rotation and revolution, which is more effective than traditional stirring methods. This ensures that the chemical components in the temporary plugging agent are evenly distributed, avoiding local concentrations that are too high or too low. At the same time, for easily agglomerated particulate components, stirring can break them up, allowing them to mix better with other components, improving the overall quality and performance stability of the temporary plugging agent. Meanwhile, during the rotation of the rotating shaft 212, the connecting rod 232 will rotate, and the two scrapers 231 will move together. During the movement of the scrapers 231, the temporary plugging agent on the inner wall of the storage tank 113 will be scraped off, reducing the adhesion of the temporary plugging agent to the inner wall of the storage tank 113, making it easier to clean the storage tank 113 later, and also greatly reducing the waste of the temporary plugging agent.

[0062] Then, the staff pushes the mobile frame 1 using handle 112 and wheels 11, moving the storage tank 113 to the designated position. Then, the pump body 322 is activated to extract the temporary plugging agent from the storage tank 113 through connecting pipe 324, and then delivers it through output pipe 321. Simultaneously, the fixed base 323, welded to the top of the mobile frame 1, provides support for the pump body 322. During the delivery of the temporary plugging agent, it is filtered through filter screen 315 to reduce impurities and prevent clogging of components. The flow rate of the temporary plugging agent can be adjusted during delivery. Specifically, rotating the handwheel 311 clockwise drives the worm gear 313, which in turn drives the worm wheel 314, which in turn drives the rotating rod 316. The rotating rod 316, during its rotation... The rotating impeller 317 rotates, and simultaneously, the rotating rod 316 rotates within the conical block 318, which provides support for the rotating rod 316. During the rotation of the rotating impeller 317, it overlaps and misaligns with the fixed impeller 319, thereby adjusting the flow rate of the temporary plugging agent. At the same time, the fixed impeller 319 provides support for the conical block 318 through its fixed connection to the inner wall of the connecting pipe 324. By precisely adjusting the flow rate of the temporary plugging agent, it can be ensured that the injected temporary plugging agent just meets the requirements for sealing the space around the wellhead and preventing gas leakage. If too much temporary plugging agent is used, it may cause difficulties in subsequent valve replacement operations or even damage the wellhead facilities. If too little is used, it will not achieve the purpose of effective temporary plugging and will pose a safety hazard of gas leakage. By precisely controlling the amount, these problems can be avoided, and the temporary plugging effect can be improved to meet the operating standards.
