Description

Technical Field

[0001] The invention relates to the technical field of skid-mounted oil and gas processing equipment, and in particular to an intelligent skid-mounted high-pressure sediment separation device for an oil and gas wellhead. Background Art

[0002] Skid-mounted equipment is an integrated way of integrating functional components on an integral base, which can be installed and moved as a whole. The so-called skid-mounted equipment can be easily moved and moved using a crowbar. It is easy to install and move. The production and assembly of skid-mounted equipment are completed in the factory, and the on-site installation workload is small. It can work after completing the connection of interface pipes and external electrical connections. Since the functional components are integrated on an integral base, they can be easily moved as a whole.

[0003] Before the gas well is officially used, the parameters of the gas well must be tested and the safety performance of its equipment must be checked. Therefore, there must be a device for separating high-pressure oil, gas, and sediment to cooperate with the equipment used for ground testing. It is mainly used for gas-liquid separation and safe removal of solid particles in the wellbore return fluid, effectively reducing damage to downstream ground equipment.

[0004] CN209129592U discloses a skid-mounted wellhead oil-gas-sand automatic separation device, comprising a mobile skid-mounted base, a separator cylinder, a gas-liquid control component, a gas-liquid-sand separation component and a hydraulic lifter, wherein the separator cylinder is fixed on the mobile skid-mounted base through a fixing frame at the bottom, a hydraulic lifter is connected to one side of the separator cylinder, and the other end of the hydraulic lifter is fixed to the mobile skid-mounted base, and a gas-liquid control component is arranged at the upper part of the separator cylinder, and a gas-liquid-sand separation component is arranged at the lower part.

[0005] The above solution does not have the function of enhancing stable parking. Although it facilitates overall movement, its stability when parked is low and it is easy to be displaced due to accidental collision and tear off the connected pipelines; the rollers are in a supporting and stress-bearing state for a long time, which is also easy to reduce their service life and cannot meet the use requirements.

[0006] In response to the above problems, a Chinese invention patent with authorization announcement number CN113108163B discloses a skid-mounted high-pressure mud and sand separation device for oil and gas wellhead testing. It achieves the effect of rooting and fixing through a series of relatively complex structures, further enhances parking stability, reduces the risk of displacement, and also ensures that the walking wheels are no longer under stress for a long time, thereby increasing their service life.

[0007] Although the above solution improves the overall stability of the separation device to a certain extent during the sediment separation process and reduces the damage to the wheel body, its structure is complex, the cost is high, it seriously damages the ground during use, and it cannot be used once the ground is a hard ground. Its applicability is poor and its flexibility is poor (once fixed to the ground, the stability will be seriously affected when fixed at the same position or a similar position for the second time, so it cannot be fixed at the same or a similar position multiple times, resulting in poor flexibility), which is not conducive to practical application. Summary of the Invention

The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to claim 1, characterized in that: The combined teeth (320) are arranged in two rows on the side wall of the load-bearing column (310), and the number of insertion holes (352) on the mating plate (351) is also two.

5. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to claim 1, characterized in that: The ground contact belt body (340) is equipped with a solidifying body (360), and the solidifying body (360) is used to further improve the parking stability of the device; The hard sheet (350) is provided with a through hole coaxial with the insertion hole (352); the reinforcing body (360) is in the shape of a nail as a whole. After the contact ground body (340) is arranged, if the ground is a soft ground, the reinforcing body (360) is passed through the insertion hole (352) and the hard sheet (350) to fix the contact ground body (340) on the ground.

6. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to any one of claims 1 to 5, characterized in that: It also includes a fixing body (130) and a reinforcing rope (400); The fixing body (130) is a through hole or a hard ring body, and is used to fix the reinforcement rope (400); The reinforcement ropes (400) are steel wire ropes, the number of which is twice that of the contact zone bodies (340), which are fixed on the fixed body (130) and respectively bind the two ends of the contact zone bodies (340) to the two ends of the bearing base plate (100), so that the deployed contact zone bodies (340) are in a stretched state and suspended in the air, thereby limiting the movement of the entire device.

7. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to claim 1, characterized in that: An annular cavity (311) is provided inside the bearing column (310); The annular cavity (311) is a circular annular cavity arranged close to the side wall of the bearing column (310); The combined teeth (320) are all rod bodies; The bearing column (310) is provided with a through hole (312) corresponding to the combined teeth (320) one by one, and the through hole (312) is a through hole; the combined teeth (320) are slidably positioned on the through hole (312) and penetrate into the annular cavity (311); An annular capsule (313) is placed inside the annular cavity (311); The annular bag (313) is an elastic bag made of rubber material and is filled with air; One end of the combined tooth (320) is fixed on the annular bag (313); the annular bag (313) plays a buffering role.

8. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads as claimed in claim 7, characterized in that: The annular bag (313) is provided with an air inlet and outlet, and the amount of gas inside is controllable; when the device is in a driving state, the annular bag (313) is controlled to be emptied so that the combined teeth (320) are shortened; before fixing, the annular bag (313) is expanded by pumping air with a manual air pump, an electric air pump, or blowing with a mouth.

9. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to claim 1, characterized in that: Also includes a winding drum (500); The reeling roller (500) is a manual reel, which is arranged near the end of the bearing base plate (100) and is provided with a rotating handle (510) for reeling up the contact zone body (340). After use, the reeling roller (500) is used to roll up and store the contact zone body (340). When in use, the reeling roller (500) is rotated to gradually release the contact zone body (340).

10. The intelligent skid-mounted high-pressure sediment separation device for oil and gas wellheads according to claim 9, characterized in that: Before its deployment, a film wider than the contact zone body (340) is laid on the target ground; after use, it is directly peeled off.
