Description

Technical Field

[0001] This invention relates to the field of deep-sea oil drilling equipment manufacturing technology, specifically to an environmentally friendly gas wellhead device. Background Technology

[0002] Wellhead equipment is a commonly used subsea oil and gas production device, also known as a tree. It is the core environmental protection equipment used at the wellhead for natural gas extraction, mainly responsible for controlling the opening, closing, and regulation of the gas production process. By optimizing the sealing structure, it reduces methane leakage and oily wastewater discharge. This device is suitable for conventional and unconventional gas fields such as shale gas, meets stringent environmental standards, and reduces the risk of soil and air pollution from extraction. It is a key piece of equipment for green gas production.

[0003] In the actual operation of traditional gas wellhead equipment, the extracted natural gas flow often carries sand and other solid particles from the formation. Driven by high-speed airflow, these sand and gravel particles continuously impact the internal structure of the wellhead equipment and the downstream pipeline system. Long-term erosion by sand and gravel particles can easily lead to damage to the wellhead equipment's seals and structural components, which in turn can cause local thinning or perforation of the pipe wall, seriously affecting the sealing performance and service life of the equipment, thereby reducing the effectiveness of the gas wellhead equipment.

[0015] Beneficial effects

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0017] I. This invention, through the setting of a separation and collection mechanism and a vibrating feeding assembly, etc., through the cooperation between the components, causes the airflow to generate centrifugal force in the spiral tube, effectively separating the sand and gravel and sliding it down the inner wall of the spiral tube into the collection column. The sealing ring and inclined ring can enhance the sealing of the collected sand. The vibrating feeding assembly causes the sand and gravel attached to the surface of the filter tube to fall off through vibration, preventing blockage. Thus, this device can efficiently and continuously separate and collect sand and gravel, reduce the erosion of the gas wellhead device body and downstream pipelines by sand and gravel, and extend the service life of the device.

[0018] Second, this invention sets up components such as a transmission energy storage component and a discharge collection component. Through the cooperation between these components, the kinetic energy of the airflow is converted into air pressure energy and stored. When the air pressure reaches a threshold, the discharge collection component is automatically driven to move the sliding ring and the tilting block, opening the discharge slot to discharge sand and gravel. Thus, this device can clean the collected sand and gravel at regular intervals without the need for additional external energy, improving energy utilization efficiency and environmental protection, while reducing manual maintenance costs.

[0019] Third, this invention, by incorporating components such as an electromagnetic block, a plug-in ring, a moving ring, and a vibrating ring, controls the movement of the tilting ring through the magnetic connection between the electromagnetic block and the moving ring. The plug-in connection between the plug-in ring and the moving block ensures the sealing of the discharge trough in the non-discharge state. The collision between the vibrating ring and the connecting block generates vibration, causing residual sand and gravel to fall off. This achieves the goal of maintaining good sealing during sand and gravel discharge, preventing gas leakage, and simultaneously enhancing cleaning efficiency through vibration, ensuring complete sand and gravel discharge, and improving the stability and reliability of the device's operation. Ultimately, this achieves the objective of low-carbon natural gas extraction. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to embodiments.

[0030] See attached document Figure 1-6 An environmentally friendly gas production wellhead device includes: a gas production wellhead device body 1, a gas production pipe 2 installed at the bottom of the gas production wellhead device body 1, and further includes:

[0031] The separation and collection mechanism 3 for separating sand and gravel includes a spiral tube 31. A filter tube 32 is installed inside the spiral tube 31, with the side of the filter tube 32 near the gas wellhead device body 1 fixedly connected to the spiral tube 31. The end of the filter tube 32 away from the gas wellhead device body 1 is fixedly connected to the gas collection pipe 2. One end of the spiral tube 31 is connected to a collection column 33, which is fixedly connected to the surface of the gas collection pipe 2. A transmission energy storage component 34 is installed at the top of the spiral tube 31. A sealing ring 35 is fixedly connected inside the collection column 33, and the top of the sealing ring 35 is inclined. The sealing ring 35 is slidably connected to an inclined ring 36 on its outer side, and the inclined ring 36 is slidably connected to the inside of the collecting column 33. The inclined ring 36 is elastically connected to the collecting column 33 via a spring. A vibrating feeding assembly 37 is installed at the top of the collecting column 33. The gas collection pipe 2 can transport the collected gas flow containing sand and gravel. The gas flow first enters the spiral tube 31, which generates centrifugal force during the flow. Simultaneously, the filter tube 32 allows impurities in the gas flow to pass through, and the filter tube 32 generates a certain resistance to the gas flow. When sand and gravel in the gas flow pass through the filter tube 32, the gas flow rate slows down, and... The combined effect of centrifugal force causes the sand and gravel to adhere to the inner wall of the spiral tube 31. The sand and gravel then gradually slide downwards along the inner wall of the spiral tube 31, eventually flowing into the collecting column 33. The collecting column 33 is used to collect the sand and gravel separated from the spiral tube 31. Its internal sealing ring 35 is inclined to prevent sand and gravel from accumulating at its top and to guide the sand and gravel towards the bottom of the collecting column 33. The inclined ring 36 is elastically connected to the collecting column 33 via a spring. When acted upon by the moving ring 4, it can be misaligned with the sealing ring 35, allowing the sand and gravel to pass smoothly through the sealing ring 35 and the inclined ring 36. The inclined ring 36 can then be reset, preventing sand and gravel from accumulating at its top. The sand and gravel stored in the collection column 33 are re-floated by the airflow, which can enhance the sealing of the collection column 33. The vibrating feeding component 37 at the top of the spiral tube 31 can then use vibration to dislodge the sand and gravel attached to the surface of the filter tube 32, avoiding the accumulation of impurities and affecting the separation effect of sand and gravel. This achieves effective separation and preliminary collection of sand and gravel in the airflow, reducing the erosion of sand and gravel on the gas wellhead device body 1 and downstream pipelines. In addition, the transmission energy storage component 34 can use the energy generated during the airflow to store energy and provide power for the subsequent operation of the device without consuming too much external energy.

[0032] See attached document Figure 1-4The transmission energy storage component 34 includes a guide pipe 341, one end of which is connected to the gas outlet end of the spiral pipe 31, and the other end of which is connected to the gas inlet end of the gas wellhead device body 1. A driven fan blade 342 is installed inside the guide pipe 341. Two sets of eccentric wheels 343 are fixedly connected to the outer side of the driven fan blade 342 via a connecting rod. A push rod 344 is hinged to the outer side of the two sets of eccentric wheels 343. A piston ring 345 is fixedly connected to the other end of the push rod 344. A compression column 346 is slidably connected to the surface of 345, and an air inlet valve is connected to one side of the compression column 346. Two sets of air pressure columns 347 are connected to the bottom of the compression column 346 via a hose. The two sets of air pressure columns 347 are connected to an air storage tank 348 via a one-way air pressure valve. A discharge collection assembly 349 is installed inside the collection column 33. The airflow after separating sand and gravel is transported to the gas wellhead device body 1 through the guide pipe 341. When the airflow flows within the guide pipe 341, it drives the driven fan blade 342 to rotate. 2. The connecting rod synchronously drives two sets of eccentric wheels 343 to rotate. During the rotation of the eccentric wheels 343, they continuously push the push rod 344, causing the push rod 344 to drive the piston ring 345 to slide back and forth in the compression column 346. The air inlet valve can control the one-way entry of external gas. The reciprocating motion of the piston ring 345 can compress the gas in the compression column 346. The compressed gas is transported to the air pressure column 347 through the hose. When the air pressure in the air pressure column 347 reaches a certain level, it enters the air storage tank 348 through the air pressure one-way valve for storage, realizing the recovery and storage of gas kinetic energy. The stored gas energy can be used to drive the discharge collection component 349 and other components without consuming a large amount of external energy, improving the energy utilization efficiency and environmental protection effect of the device. It also provides power support for the realization of other functions of the device. The air storage tank 348 is existing technology. It can supply gas to the support column 3495 when the internal air pressure reaches a certain threshold, and can automatically close when the internal air pressure drops to a certain threshold, no longer supplying gas to the support column 3495.

[0033] See attached document Figure 3-5The discharge collection assembly 349 includes a sliding ring 3491, which is slidably connected to the interior of the collection column 33. An inclined protruding ring 3492 is fixedly connected to the interior of the collection column 33, and the inclined protruding ring 3492 is located at the top of the sliding ring 3491. Several sets of movable columns 3493 are fixedly connected to the bottom of the sliding ring 3491. A moving rod 3494 is elastically connected to the bottom of each movable column 3493 via a spring. The top of the moving rod 3494 penetrates the interior of the sliding ring 3491 and extends to the top of the sliding ring 3491. A support column 3495 is slidably connected to the surface of the moving rod 3494, and the support column 3495 is connected to the collection column. The internal structure of the collection column 33 is fixedly connected, and the support column 3495 is connected to the gas storage tank 348 via a hose. Several sets of inclined blocks 3496 are slidably connected inside the collection column 33, and the outer sides of the inclined blocks 3496 are elastically connected to the collection column 33 via springs. Movable blocks 3497 are fixedly connected to the outer sides of the several sets of inclined blocks 3496, and the movable blocks 3497 are slidably connected to the collection column 33. Several sets of discharge slots are opened at the bottom of the collection column 33, and the interior of the discharge slots is slidably connected to the movable blocks 3497. The moving rod 3494 is fixedly connected to the interior of the support column 3495 via a spring. When the gas stored in the gas storage tank 348 reaches a threshold, the storage... Gas canister 348 delivers gas to support column 3495 via hose. Gas pressure pushes moving rod 3494 upwards. The movement of moving rod 3494, via spring, pushes movable column 3493 upwards. The movement of movable column 3493 pushes sliding ring 3491 at its top to slide upwards inside collection column 33. When sliding ring 3491 moves to the bottom of inclined convex ring 3492 and comes into contact with it, sliding ring 3491 is stopped and no longer moves, thus stopping movable column 3493. Meanwhile, moving rod 3494 continues to move, contacting the bottom of inclined block 3496 and pushing it to move. Inclined block 3496, under force, moves outwards, causing... The movable block 3497 on the outer side slides, which opens the discharge trough, allowing the sand and gravel in the collection column 33 to be discharged downwards through the discharge trough. Subsequently, the collection column 33 can discharge gas by pushing the column 10. When the gas pressure in the gas storage tank 348 drops to a certain level, gas is no longer supplied to the collection column 33. When the gas pressure in the support column 3495 decreases, the spring at the bottom of the moving rod 3494 will pull it to reset, thereby driving the movable column 3493 to reset, causing the sliding ring 3491 to descend. The tilting block 3496 and the movable block 3497 reset under the action of the spring, and the movable block 3497 re-seals the discharge trough to prevent gas or impurities from leaking.

[0034] The air pressure column 347 has a sliding connection to a movable ring 4. The top of the movable ring 4 is fixedly connected to the bottom of the inclined ring 36 via a movable rod. The movable ring 4 is also elastically connected to the interior of the air pressure column 347 via a spring. An electromagnetic block 5 is magnetically connected to the bottom of the movable ring 4 and is fixedly connected to the interior of the gas collection pipe 2. The electromagnetic block 5 is also electrically connected to the gas storage tank 348 via a controller. When the compression column 346 delivers gas into the air pressure column 347, the air pressure inside the air pressure column 347 increases, thereby pushing the movable ring 4 to move. When the movable ring 4 moves, it causes the inclined ring 36 to slide upward within the collection column 33, causing it to misalign with the sealing ring 35, thus opening the sand and gravel flow channel for easier collection. The sand and gravel temporarily stored in the collection column 33 flows downwards; then, the moving ring 4, under the action of its connected spring, pushes the compressed gas, causing the gas to move into the interior of the gas storage tank 348 through the air pressure check valve. When the air pressure in the gas storage tank 348 reaches the set value, the gas storage tank 348 will energize the electromagnetic block 5 through the controller. After the electromagnetic block 5 generates magnetism, it will exert a downward attraction on the moving ring 4, fixing the moving ring 4 so that it will no longer move due to the influence of the gas delivered by the compression column 346; the gas in the compression column 346 will pass through the threshold of the air pressure check valve and be directly delivered into the interior of the gas storage tank 348, avoiding leakage of collected gas due to the movement of the tilting ring 36 during the sand and gravel cleaning process. It is worth noting that the electromagnetic block 5 is existing technology.

[0035] The bottom of the electromagnetic block 5 is magnetically connected to a plug ring 6, which is plugged into the top of the movable block 3497. The plug ring 6 is also slidably connected to the inner wall of the collecting column 33. The plug ring 6 is elastically connected to the inside of the collecting column 33 via a spring. When the electromagnetic block 5 is energized and generates magnetism, it will exert an upward pulling force on the plug ring 6 at the bottom. The plug ring 6 slides upward along the inner wall of the collecting column 33 and disengages from the plugging with the top of the movable block 3497. After the movable block 3497 loses its limit, it can slide freely under the action of the spring on the outside of the inclined block 3496, creating conditions for opening the discharge slot. When the electromagnetic block 5 is de-energized and the magnetism disappears, the plug ring 6 slides downward and re-plugs into the top of the movable block 3497, limiting and fixing the movable block 3497 to prevent it from sliding due to airflow impact or vibration in the non-discharge state, ensuring that the discharge slot is always sealed and maintaining the airtightness of the collecting column 33.

[0036] The bottom of the collecting column 33 is detachably connected to a collecting ring 7, and the top of the collecting column 33 is equipped with a filter plate 8, which is fixedly connected to the gas sampling pipe 2. Several sets of positioning blocks 9 are fixedly connected inside the collecting column 33, and the positioning blocks 9 are located on top of the sliding ring 3491. The detachable collecting ring 7 at the bottom of the collecting column 33 can receive the sand and gravel discharged from the discharge trough. When the sand and gravel accumulate to a certain amount, the staff can remove the collecting ring 7 for cleaning or recycling to prevent the sand and gravel from scattering and polluting the site. The filter plate 8 at the top of the collecting column 33 is fixed to the gas sampling pipe 2 and can intercept the sand and gravel that separates and slides down from the spiral pipe 31 to prevent the sand and gravel from sliding back into the gas sampling pipe 2, thereby improving the separation effect. The positioning blocks 9 inside the collecting column 33 are located on top of the sliding ring 3491 and can limit the rising distance of the sliding ring 3491 to prevent the sliding ring 3491 from rising excessively.

[0037] See attached document Figure 2-6 The vibrating feeding assembly 37 includes a cam 371, which is fixedly connected to a connecting rod. A movable block 372 is provided at the bottom of the cam 371. A sealing box 373 is elastically connected to the bottom of the movable block 372 via a spring, and the sealing box 373 is fixedly connected to a guide tube 341. A vibrating block 374 is fixedly connected to the bottom of the movable block 372 and is located at the top of the filter tube 32. A guide plate 375 is fixedly connected to the bottom of the sealing box 373. When the connecting rod drives the driven fan blade 342 and the eccentric wheel 343 to rotate, it synchronously drives the cam 371 to rotate. The protruding part of the cam 371 periodically squeezes... The movable block 372 slides downward against the spring force, and the vibrating block 374 at the bottom contacts the top of the filter tube 32 and transmits vibration, causing impurities such as sand and gravel attached to the surface of the filter tube 32 to fall off, thus preventing the filter holes of the filter tube 32 from becoming clogged. When the protruding part of the cam 371 rotates away, the movable block 372 returns to its original position under the action of the spring, and the vibrating block 374 separates from the filter tube 32, waiting for the next compression. The sealing box 373 can protect the movable block 372 and the spring, preventing the movement of the parts from being affected by the airflow. The guide plate 375 at the bottom of the sealing box 373 can guide the flow direction of the airflow, preventing the sealing box 373 from affecting the stable flow of the airflow.

[0038] One side of the support column 3495 is connected to the push column 10 via a pressure valve and a hose. The push column 10 is fixedly connected to the inside of the collection column 33. A vibration ring 11 is slidably connected inside the push column 10, and the vibration ring 11 is fixedly connected to the inside of the push column 10 via a spring. A connecting block 12 is provided on the top of the vibration ring 11, and the connecting block 12 is fixedly connected to the inside of the collection column 33. When the air pressure inside the support column 3495 reaches a preset threshold, the pressure valve will open, and the gas inside the support column 3495 can be transported to the inside of the push column 10 through the hose in the prior art. After the gas enters the push column 10, it will drive the vibration inside. The ring 11 slides along the inner wall of the push column 10. During the sliding process, the vibrating ring 11 will contact and collide with the connecting block 12 at the top, thereby generating vibration. Subsequently, the vibrating ring 11 will be pulled back by the spring at its bottom, squeezing and expelling the gas inside the push column 10. Then, the pressure valve reaches the preset threshold again. As the gas storage tank 348 delivers gas to the support column 3495, the support column 3495 will continuously and intermittently deliver gas to the inside of the push column 10. This vibration will be further transmitted to the inside of the collection column 33, which can cause the residual sand and gravel attached to the collection column 33 and its connecting parts to fall off, thereby enhancing the efficiency of sand and gravel discharge and cleaning.

[0039] Working principle: During use, the gas sampling pipe 2 first delivers a gas flow containing sand and gravel. The gas flow first enters the spiral tube 31 of the separation and collection mechanism 3. The spiral tube 31 generates centrifugal force in the flow of the gas flow, while the internal filter tube 32 creates a certain resistance to the gas flow. After the sand and gravel in the gas flow passes through the filter tube 32, they adhere to the inner wall of the spiral tube 31 due to the combined effect of the slowed flow velocity and centrifugal force, and then gradually slide down the inner wall into the collection column 33. The sealing ring 35 inside the collection column 33 is set at an angle, which can prevent sand and gravel from accumulating at the top and guide the sand and gravel to gather at the bottom. The inclined ring 36 is elastically connected to the collection column 33 by a spring, and will subsequently cooperate with the moving ring 4 to implement the action. The sand and gravel collection channel is opened and closed. At the same time, the vibrating feeding component 37 at the top of the spiral tube 31 works synchronously. The rotation of the connecting rod in the transmission energy storage component 34 will drive the cam 371 to rotate. The cam 371 will periodically squeeze the moving block 372. When the moving block 372 slides down against the spring force, the vibrating block 374 at its bottom will contact the filter tube 32 and transmit vibration, causing the sand and gravel attached to the surface of the filter tube 32 to fall off, preventing the filter holes of the filter tube 32 from being blocked. The sealing box 373 can protect the moving block 372 and the spring from the airflow. The guide plate 375 at its bottom can also guide the airflow to flow stably, thereby completing the initial separation and anti-blocking treatment of sand and gravel in the airflow.

[0040] The clean gas flow after sand and gravel separation is delivered to the gas wellhead device body 1 through the guide pipe 341 of the transmission energy storage component 34. As the gas flow within the guide pipe 341, it drives the driven fan blade 342 to rotate. The driven fan blade 342 synchronously drives two sets of eccentric wheels 343 and the cam 371 to rotate via a connecting rod. During the rotation of the eccentric wheels 343, they continuously push the push rod 344, causing the push rod 344 to drive the piston ring 345 to slide back and forth within the compression column 346. The intake valve controls the unidirectional entry of external gas into the compression column 346. The reciprocating motion of the piston ring 345 compresses the gas within the compression column 346. The compressed gas is then delivered to the pressure column 347 via a hose. The increased pressure within the pressure column 347 pushes the moving ring 4 to move. The moving ring 4, via a movable rod, drives the tilting ring 36 to slide upwards within the collection column 33, causing the tilting ring 36 to contact the sealing ring 347. 5. The misalignment opens the sand and gravel flow channel, facilitating the downward flow of sand and gravel temporarily stored in the collection column 33. Then, the moving ring 4, under the action of the spring, pushes the compressed gas, allowing the gas to enter the storage tank 348 for storage through the air pressure check valve. When the air pressure in the storage tank 348 reaches the set value, the storage tank 348 energizes the electromagnetic block 5 through the controller. The electromagnetic block 5 generates magnetism, which exerts a downward attraction on the moving ring 4, fixing the moving ring 4 so that it is no longer affected by the gas transported by the compression column 346. At this time, the gas in the compression column 346 can directly enter the storage tank 348 through the air pressure check valve, realizing the energy storage of gas kinetic energy recovery. At the same time, when the electromagnetic block 5 is energized, it will generate an upward pulling force on the bottom insertion ring 6, causing the insertion ring 6 to slide upward along the inner wall of the collection column 33 and disengage from the insertion of the movable block 3497, releasing the limitation on the movable block 3497 and preparing for the subsequent opening of the discharge trough.

[0041] When the gas level in the gas storage tank 348 reaches a threshold, the gas storage tank 348 delivers the gas through a hose to the support column 3495 of the discharge collection assembly 349. The gas pressure pushes the moving rod 3494 upward, and the moving rod 3494 pushes the movable column 3493 upward via a spring. The movable column 3493 causes the sliding ring 3491 to slide upward within the collection column 33 until the sliding ring 3491 is pressed tightly against the inclined convex ring 3492 and is limited. The positioning block 9 further prevents the sliding ring 3491 from rising excessively. The moving rod 3494 continues to move upward and pushes the tilting block 3496 to move outward. The tilting block 3496 drives the movable block 3497 to slide, causing the discharge groove at the bottom of the collecting column 33 to open. The sand and gravel in the collecting column 33 fall into the collecting ring 7 at the bottom through the discharge groove. The collecting ring 7 is detachable, making it convenient for subsequent cleaning or recycling of the sand and gravel by the staff. The filter plate 8 at the top of the collecting column 33 can intercept the sand and gravel that slides off the spiral tube 31, preventing it from re-entering the gas sampling pipe 2. When the gas pressure in the support column 3495 reaches the preset threshold, When the pressure valve opens, the gas inside the support column 3495 is delivered to the push column 10 through the hose, pushing the vibrating ring 11 to slide along the inner wall of the push column 10. The vibration generated by the collision between the vibrating ring 11 and the connecting block 12 is transmitted to the collection column 33, causing residual sand and gravel to fall off to improve cleaning efficiency. Afterwards, the vibrating ring 11 returns to its original position under the action of the spring, and the above operation is repeated to achieve the vibration of the collection column 33. When the gas pressure in the gas storage tank 348 drops to a certain level, the gas storage tank 348 stops supplying gas to the support column 3495, and the moving rod 34... 94 resets under the action of the spring, driving the movable column 3493 and sliding ring 3491 to reset. The tilting block 3496 and movable block 3497 also reset under the action of the spring and seal the discharge groove. At the same time, the electromagnetic block 5 is de-energized, and the plug ring 6 slides down and re-plugs into the movable block 3497 to ensure the discharge groove is sealed. This completes a complete cycle of sand and gravel separation, energy storage, discharge and reset. The continuous operation of the device can reduce the erosion of sand and gravel on the gas wellhead device body 1 and downstream pipelines, and improve the service life and environmental protection of the device.
