Description

Technical Field

[0001] The invention relates to the technical field of wellhead sand removal, in particular to a continuously operating high-pressure wellhead cyclone sand removal device. Background Art

[0002] During the oil and gas testing, fracturing and flowback production of high-pressure oil and gas wells, solid particles in the formation flow out of the wellbore with the oil and gas flow. The sand carried by the high-pressure oil and gas flow poses a great threat to the safe and stable operation of surface equipment and pipelines, and has an immeasurable negative impact on the normal production of oil and gas fields. In order to clean the sediment in the oil and gas, the oil and gas are generally cleaned through a cyclone decontaminant.

[0003] At present, when the cyclone decontaminator is in normal working condition, the sand and impurities remaining in the oil and gas after being treated by the cyclone decontaminator will still enter the sewage pipe and enter the next process. At this time, a filter plate will be set at the outlet of the sewage pipe. However, as the impurities accumulated on the filter plate increase, the filter plate must be cleaned, otherwise it will cause the filter plate to be blocked, which will affect the oil and gas passing efficiency. For this reason, we propose a continuously operating high-pressure wellhead cyclone desanding device. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-13The present invention provides a technical solution: a continuously operated high-pressure wellhead cyclone sand removal device, comprising a base frame 1 and a plurality of decontaminants 2 arranged on the base frame 1, the decontaminants 2 are provided with a sewage inlet pipe 14 and a sewage discharge pipe 13, a cyclone sheet 24 is provided in the decontaminant 2, and a mud discharge trough 15 is provided on the base frame 1; it also includes: a driving motor 3 arranged on the base frame 1, and a cleaning member 11 arranged on the decontaminant 2, the cleaning member 11 is spirally descended by the driving motor 3, and then the surface of the cyclone sheet 24 is scraped, and a decontaminant 24 is provided on the base frame. 1, the cleaning pipe 5 is connected to the sewage pipe 13, and there is also a filter plate 12 arranged in the cleaning pipe 5, the cleaning pipe 5 intercepts sand and impurities in the oil and gas, and a partition 6 is arranged in the cleaning pipe 5, the cleaning pipe 5 is divided into two areas by the partition 6, the two areas of the cleaning pipe 5 are staggeredly fed by the partition 6 and the partition 6 cooperates with the driving motor 3, and there is also a drainage pipe 8 arranged in the partition 6, the oil and gas on one side of the partition 6 is guided to the other side thereof through the drainage pipe 8 and the filter plate 12 is reversely flushed.

[0040] See also Figure 1-Figure 4 The partition 6 includes a partition block 66, which is arranged in the cleaning pipe 5, and the filter plates 12 are arranged on both sides of the partition block 66. The partition block 66 evenly divides the cleaning pipe 5 into two areas. A accommodating chamber 63 is provided in the partition block 66, and a mounting frame 64 is provided in the accommodating chamber 63. A water inlet 61 and a water outlet 62 are provided on both sides of the partition block 66. The water outlet 62 and the water inlet 61 are both connected to the accommodating chamber 63. A guide plate 65 is provided on the partition block 66, and a supporting mechanism 9 is provided in the accommodating chamber 63. The oil and gas flow alternately through the two sides of the partition block 66 through the rotation of the guide plate 65. Therefore, when some filter plates 12 of the partition block 66 are cleaned, the filter plates 12 on the other side of the partition block 66 can still filter the oil and gas, thereby realizing continuous operation.

[0041] See also Figure 8 The guide plate 65 is provided with a fan-shaped hole, and a collar 651 is provided on the guide plate 65. The collar 651 is sleeved on the partition block 66. The guide plate 65 is rotatably connected to the partition block 66 through the collar 651. A cross bar 10 is provided in the accommodating chamber 63. The guide plate 65 is provided on the cross bar 10. A notch 652 is provided on the collar 651. Drain ports 51 are provided on both sides of the cleaning pipe 5. The collar 651 covers the connection between the drain port 51 and the cleaning pipe 5. Through the fan-shaped hole provided on the guide plate 65, when the guide plate 65 rotates at a certain angle, the other side of the partition block 66 will not pass through the oil and gas. The notch 652 provided on the collar 651 enables the drain port 51 to be in a state of communication with the cleaning pipe 5 only when the collar 651 is at a specified angle.

[0042] See also Figure 5 and Figure 7The supporting mechanism 9 includes a missing gear 91, which is arranged on the cross bar 10. A rack 92 is slidably arranged in the accommodating chamber 63. The rack 92 penetrates the side wall of the partition block 66. The rack 92 is arranged on both sides of the missing gear 91. Flip plates 7 are rotatably arranged on both sides of the partition block 66. The rack 92 penetrates the side wall of the partition block 66 and is slidably connected with the flip plate 7. A slide groove 93 is provided on the flip plate 7. The rack 92 is slidably connected with the flip plate 7 through the slide groove 93. During the rotation of the missing gear 91, the missing gear 91 engages with the rack 92, so that the rack 92 moves and lifts the flip plate 7 on one side of the partition block 66, thereby increasing the pressure in the cleaning pipe 5 so that the oil and gas can better enter the drainage pipe 8.

[0043] See also Figure 3 and Figure 5 A mounting rod 71 is provided on the flip plate 7, and the flip plate 7 is rotatably connected to the partition block 66 through the mounting rod 71. Torsion springs 72 are sleeved at both ends of the mounting rod 71, and both ends of the torsion spring 72 are respectively connected to the partition block 66 and the flip plate 7. The torsion spring 72 is set so that the flip plate 7 can be reset immediately when the supporting force of the rack 92 is lost, thereby avoiding the situation where the flip plate 7 causes the pressure in the cleaning pipe 5 to increase when the oil and gas flow normally.

[0044] See also Figure 6-7 The drainage pipe 8 is rotatably connected to the accommodating chamber 63 through the mounting frame 64, and the drainage pipe 8 is arranged on the cross bar 10. A water inlet channel 81 is opened on one side of the drainage pipe 8, and a water outlet channel 82 is opened on the other side of the drainage pipe 8. The water inlet channel 81 can be connected to the water inlet 61, and the water outlet channel 82 can be connected to the water outlet 62. When the drainage plate 65 rotates a certain angle and the oil and gas on the other side of the partition block 66 do not pass through, the water inlet channel 81 is already connected to the water inlet 61. In this way, when the oil and gas on the other side of the partition block 66 do not flow through, the oil and gas on one side of the partition block 66 can reach the other side of the partition block 66 through the water inlet channel 81 and the water outlet channel 82, thereby reversely flushing the filter plate 12.

[0045] See also Fig.11 A partition plate 22 is provided in the dirt separator 2, and a water outlet pipe 21 is provided at the upper end of the dirt separator 2. The water outlet pipe 21 passes through the upper end of the dirt separator 2 and extends into the dirt separator 2. The water outlet pipe 21 passes through the partition plate 22. A swirl sheet 24 is provided in the dirt separator 2. The swirl sheet 24 is arranged below the partition plate 22. A connecting pipe 23 is provided on the side wall of the dirt separator 2. The dirt separator 2 is connected to the sewage inlet pipe 14 through the connecting pipe 23, and the dirt separator 2 is connected to the sewage discharge pipe 13 through the water outlet pipe 21.

[0046] See also Figure 9-10A vertical rod 4 is rotatably arranged on the partition plate 22, and the vertical rod 4 passes through the upper surface of the dirt remover 2 and extends into the dirt inlet pipe 14. A worm 41 is arranged on one of the vertical rods 4, and a worm wheel 101 is arranged on the cross bar 10. The worm 41 is engaged with the worm wheel 101. A pulley 32 is arranged on the drive motor 3 and the cross bar 10, and a belt 31 is arranged between the pulley 32. A pulley 2 43 is arranged on the cross bar 10, and a belt 2 42 is arranged between the pulleys 43. Through the deceleration effect between the worm 41 and the worm wheel 101, the cross bar 10 rotates slower than the vertical rod 4, so that when the ring 112 moves a sufficient distance, the guide plate 65 can just rotate 180°.

[0047] See also Figure 12-13 A cleaning member 11 is slidably provided on the partition plate 22, and the cleaning member 11 is sleeved on the surface of the water outlet pipe 21. A spiral cleaning piece 111 is provided on the cleaning member 11, and the spiral cleaning piece 111 is located below the partition plate 22. The spiral cleaning piece 111 has the same structure as the swirl piece 24. A rotating ring 112 is rotatably provided on the cleaning member 11, and the rotating ring 112 is threadedly connected to the cross bar 10. The cross bar 10 enables the sleeve 112 threadedly connected thereto to drive the cleaning member 11 to descend. Since the spiral cleaning piece 111 has the same structure as the swirl piece 24, as the spiral cleaning piece 111 contacts the swirl piece 24, the spiral cleaning piece 111 is closely attached to the surface of the swirl piece 24. As the cleaning member 11 descends, the spiral cleaning piece 111 scrapes the surface of the swirl piece 24, scrapes off the mud and sand attached to the surface of the swirl piece 24, cleans the surface of the swirl piece 24, and there is no need for the decontaminator 2 to stop inletting oil and gas.

[0048] In use, the oil and gas that need to be desanded enter the desanding device 2 through the inlet pipe 14 via the connecting pipe 23 in the tangential direction of the desanding device 2, and generate a swirl in the desanding device 2. At the same time, the oil and gas further enhance the swirl effect through the swirl sheet 24, and the heavier sediment sinks, while the oil and gas enter the cleaning pipe 5 through the outlet pipe 21 via the drain pipe 13. Since the space in the cleaning pipe 5 is divided into two areas by the partition block 66, and the guide plate 65 blocks one area, the cleaning pipe 5 is The sand and impurities of oil and gas enter the unblocked space in the cleaning pipe 5 through the fan-shaped holes on the drainage plate 65, and the sand and impurities are filtered through the filter plate 12. As the sand and impurities accumulate on the filter plate 12, the vertical rod 4 is rotated by starting the drive motor 3, and then the cross bar 10 is rotated through the worm gear 101 and the worm 41, and the drainage plate 65, the drainage pipe 8 and the missing gear 91 rotate synchronously with the cross bar 10. When the water inlet channel 81 is connected to the water inlet 61, The drainage plate 65 does not open the area on the other side of the partition block 66. At this time, the oil and gas containing sand and impurities have flowed through the drainage pipe 8 and entered the other side of the partition block 66 through the water outlet channel 82. In the process of the water inlet channel 81 on the drainage pipe 8 gradually overlapping with the water inlet 61, the missing gear 91 meshes with the rack 92, so that the rack 92 moves and lifts the flip plate 7 on one side of the partition block 66, thereby increasing the pressure in the cleaning pipe 5 so that the oil and gas can better enter the drainage pipe 8. As the oil and gas on the other side of the partition block 66 increases, part of the oil and gas passes through the other side of the filter plate 12, washes down the sand and impurities accumulated on one side of the filter plate 12, and is discharged from the sewage outlet 51 after passing through the gap 652. As the cross bar 10 continues to rotate, the drainage plate 65 completely opens the other side of the partition block 66, and the collar 651 blocks the sewage outlet 51. In this way, the sand and impurities in the oil and gas flowing through can be better cleaned by the cleaned filter plate 12.

[0049] During the rotation of the cross bar 10, the cross bar 10 causes the collar 112 connected thereto by a thread to drive the cleaning member 11 to descend. Since the spiral cleaning sheet 111 has the same structure as the swirl sheet 24, as the spiral cleaning sheet 111 contacts the swirl sheet 24, the spiral cleaning sheet 111 is close to the surface of the swirl sheet 24. As the cleaning member 11 descends, the spiral cleaning sheet 111 scrapes the surface of the swirl sheet 24, scrapes off the mud and sand attached to the surface of the swirl sheet 24, and cleans the surface of the swirl sheet 24. There is no need for the dirt remover 2 to stop taking in oil and gas. When the spiral cleaning sheet 111 completely covers the swirl sheet 24, the drive motor 3 rotates in the opposite direction to lift the cleaning member 11, and at this time the guide plate 65 flips over again.
