Description

Technical Field

[0001] The present invention relates to the technical field of fracturing manifolds, in particular to a dual-channel high-pressure fracturing manifold. Background Art

[0002] During the production of oil and gas, fracturing manifolds are used to transport oil and gas, so formation gravel and fracturing gravel will reach the surface along with the oil and gas. Sand production in oil and gas wells will cause serious abrasion of surface and downhole equipment, and even cause well sticking. The maintenance workload such as sand flushing, pump inspection and ground tank cleaning will increase dramatically. Sand will bury the oil layer or cause sand blockage in the wellbore, causing production suspension. Severe sand production may even cause well wall collapse and damage to oil casing, increasing the cost of oil and gas extraction.

[0039] The working principle and beneficial effects of the above scheme are as follows:

[0040] The present application sets up two groups of pipelines, a first main pipeline 1 and a second main pipeline 2 are set in parallel, and a switch 3 is used to realize the selective connection of the first main pipeline 1 and the second main pipeline 2. When the filter screen of one of the pipelines is dirty or blocked, the rotating block 5 is rotated to make the connecting part 6 connect to the other pipeline. At this time, the dirt and the filter screen of the blocked pipeline can be cleaned and replaced without affecting the transportation of the pipeline.

[0041] Example 2

[0042] Please refer to Figure 2 On the basis of Example 1, the first main line 1, the second main line 2 and the switch 3 are connected through a connecting component, and the connecting component includes a first interface 7 connected to the main line and a second interface 8 connected to the connecting part 6. The first interface 7 is provided on the first connecting shell 9, and the second interface 8 is provided on the second connecting shell 15. The other end of the second connecting shell 15 is provided with a connecting port 14, and the first connecting shell 9 can be connected to the connecting port 14.

[0043] A limiting shaft 11 is fixedly connected to the first connecting shell 9, and a plugging head 12 is slidably connected to the limiting shaft 11. The plugging head 12 can seal the lower port of the first connecting shell 9. A first spring 13 is provided between the plugging head 12 and the upper end of the first connecting shell 9. The first spring 13 is sleeved on the limiting shaft 11.

[0044] A protrusion 10 is provided on the outer side of the first connecting shell 9 .

[0045] An abutment rod 16 is fixedly connected to the second connection shell 15. A sealing sleeve 17 is provided on the outer periphery of the abutment rod 16. The sealing sleeve 17 is slidably connected to the second connection shell 15. An opening is provided at the upper end of the sealing sleeve 17. The upper end of the abutment rod 16 can seal the opening at the upper end of the sealing sleeve 17.

[0046] A second spring 18 is provided between the sealing sleeve 17 and the lower end of the second connecting shell 15 , and the second spring 18 is sleeved on the abutting rod 16 ;

[0047] A locking buckle 20 is provided on the outside of the sealing sleeve 17 , and the locking buckle 20 is slidably connected to the inner wall of the second connecting shell 15 . The locking buckle 20 is tilted, and the lower end of the locking buckle 20 is connected to the third spring 19 .

[0048] The working principle and beneficial effects of the above scheme:

[0049] When connecting the first main line 1, the second main line 2 and the switch 3, it is done through the connection component, which is convenient and quick;

[0050] Insert the first connecting shell 9 connecting the first main line 1 and the second main line 2 into the connecting port 14. The end face of the first connecting shell 9 contacts the sealing sleeve 17, squeezing the sealing sleeve 17. After overcoming the elastic force of the second spring 18, the sealing sleeve 17 moves to separate from the upper end of the abutting rod 16. At this time, the sealing state between the abutting rod 16 and the sealing sleeve 17 is released, and conduction is achieved.

[0051] During this process, the abutting rod 16 squeezes the plugging head 12, and the plugging head 12 overcomes the elastic force of the first spring 13 and slides toward the inside of the first connecting shell 9. The plugging head 12 is separated from the end surface of the first connecting shell 9, and the sealing state between the plugging head 12 and the first connecting shell 9 is released, thereby achieving conduction.

[0052] During the insertion process, the protrusion 10 on the outer side of the first connecting shell 9 passes through the locking buckle 20 and squeezes the locking buckle 20, causing the locking buckle 20 to retract against the elastic force of the third spring 19. When the protrusion 10 has completely passed the locking buckle 20, the locking buckle 20 is reset under the elastic force of the third spring 19 and is locked onto the protrusion 10, completing the fixation of the first connecting shell 9 and the second connecting shell 15, that is, completing the connection between the first main line 1, the second main line 2 and the switch 3;

[0053] When the connection assembly of the present application is used to connect the first main line 1, the second main line 2 and the switch 3, the pipeline will be connected only after the first main line 1, the second main line 2 and the switch 3 are connected. During the connection, the ports of the first main line 1 and the second main line 2 will remain sealed, and the connecting part 6 of the switch 3 will also remain sealed, effectively preventing leakage of substances in the pipeline.

The inlet 33 is connected to the first main line 1, and the outlet 37 is connected to the second main line 2.

[0056] A trigger rod 38 is provided in the outlet 37. The trigger rod 38 passes through the side wall of the outlet 37 and is slidably connected to the side wall of the outlet 37. One end of the trigger rod 38 located in the outlet 37 is rotatably connected to a crushing plate. The crushing plate is tilted in the outlet 37 and is slidably connected to the inner wall of the outlet 37.

[0057] The trigger rod 38 is inserted into the pressure box 39. A fourth spring 40 is provided between the trigger rod 38 and the pressure box 39. The pressure box 39 is fixedly connected to the regulating chamber 35.

[0058] The trigger lever 38 is fixedly connected to a linkage rod 49, which is fixedly connected to a rack 41. The rack 41 meshes with a gear 48. The rotation axis of the gear 48 passes through the side wall of the outlet 37 and is fixedly connected to an adjustment ball 42. The gear 48 is fixedly connected to the adjustment ball 42.

[0059] A through hole is provided at the center of the adjusting ball 42 , and the adjusting ball 42 is rotatably connected to the outlet 37 .

[0060] An adjusting impeller 34 is provided in the adjusting chamber 35 , and the adjusting impeller 34 is fixedly connected to an adjusting shaft 36 , and the adjusting shaft 36 is rotatably connected to the adjusting chamber 35 ;

[0061] The outer periphery of the regulating impeller 34 is provided with a filter screen, and the filter screen is located between the inlet 33 and the outlet 37;

[0062] A rotary disk is provided on the outer periphery of the adjustment shaft 36, and the adjustment shaft 36 is rotatably connected to the cavity inside the side wall of the adjustment chamber 35. The rotary disk is provided with a slide groove for accommodating the trigger slide 46. An electromagnet 44 is fixedly connected to the slide groove of the rotary disk. A fifth spring 47 is provided between the electromagnet 44 and the trigger slide 46. A protrusion is provided on the rotary disk;

[0063] An extrusion head 50 is provided on one side of the turntable, and the extrusion head 50 abuts against the turntable. The extrusion head 50 is fixedly connected to a striking rod 54, and the striking rod 54 passes through the side wall of the adjustment chamber 35. The striking rod 54 is fixedly connected to a striking head 45, and the striking head 45 is located on one side of the filter screen;

[0064] A sixth spring 51 is provided between the extrusion head 50 and the side wall of the regulating chamber 35 .

[0065] A pressure plate 52 is fixedly connected to the striking rod 54, and a liquid infusion pipeline 53 is provided in the cavity between the pressure plate 52 and the side wall of the regulating chamber 35, which is connected to the cleaning liquid chamber 43. The cleaning liquid chamber 43 is fixedly connected to the regulating chamber 35, and a hole leading to the filter plate is provided in the cavity between the pressure plate 52 and the side wall of the regulating chamber 35.

[0066] An electric trigger is provided between the trigger rod 38 and the pressure box 39 , and the electric trigger is connected to the electromagnet 44 .

[0067] The working principle and beneficial effects of the above scheme are as follows:

[0068] When the material in the pipeline flows through the bend or diameter-changing section at an excessively fast flow rate during use, it will cause impact on the pipeline, and in severe cases, damage the pipeline and cause leakage. By adjusting the flow rate of the material in the pipeline, the occurrence of such situations can be effectively suppressed.

[0069] After the material enters the regulating chamber 35 through the inlet 33, it flows out through the outlet 37. If the flow rate is too high through the outlet 37, it will squeeze the crushing plate. The crushing plate drives the trigger rod 38 to move outward, overcoming the pressure of the fourth spring 40. The rack 41 fixed to the trigger rod 38 drives the gear 48 to rotate, thereby rotating the regulating ball 42 in the outlet 37. The through hole in the center of the regulating ball 42 is partially blocked by the inner wall of the outlet 37, which changes the size of the through hole, reducing the amount of material flowing through the outlet 37, lowering the pressure, and slowing the flow rate.

[0070] When the flow rate at the outlet 37 slows down to a certain level, the fourth spring 40 is in a relaxed state, the trigger rod 38 contacts the electric trigger, and the electromagnet 44 is de-energized. The trigger slide 46 is inserted between the turntable and the adjustment shaft 36 under the action of the fifth spring 47, and the adjustment impeller 34 is rotated by the adjustment shaft 36. That is, the turntable is rotated by the adjustment shaft 36, and the raised block on the turntable reciprocates through the extrusion head 50 and squeezes the extrusion head 50. The striking rod 54 causes the striking head 45 to strike the filter screen, ensuring the cleanliness of the filter screen and avoiding the flow rate reduction caused by the filter screen being clogged.

[0071] During the striking process of the striking head 45 , the pressing plate 52 moves accordingly, and the cavity between the pressing plate 52 and the side wall of the regulating chamber 35 is repeatedly transformed, so that the cleaning liquid in the cleaning liquid chamber 43 acts on the filter screen to clean the filter screen.
