A large-diameter high-low pressure distribution fracturing remote control adjustable straight-line manifold device

Abstract

The present invention relates to the technical field of oil well mining, and discloses a large-diameter high-low pressure distribution fracturing remotely controlled adjustable one-line manifold device, comprising a bracket, two flow blocks fixedly connected to the top of the bracket, and a flow pipe connected through the two flow blocks. The present invention aims to solve the problem that fine particles in the liquid will precipitate when the liquid is in a static state. A pressure mechanism and a dispersion mechanism are arranged inside the device. As the flow rate of the liquid increases, the rotating plate will be forced to continue to rotate upward. At this time, the rotating plate will press the receiving plate to continue to rotate upward and increase the angle between the receiving plate and the rotating plate. The rotating plate drives the fixed plate and the arc-shaped slide plate to slide along the outer wall of the receiving plate through the rotating rod three. The through hole one and the through hole two are in an overlapping state. The accumulated small particles will fall downward through the above overlapping gap, effectively ensuring that the liquid flows again after sedimentation and that sufficient fine particles are still retained in the liquid.

Description

Technical Field

[0001] The invention relates to the technical field of oil well mining, in particular to a large-diameter high-low pressure distribution fracturing remotely controlled adjustable straight-line manifold device. Background Art

[0002] With advancements in the oil and gas industry, natural gas extraction is moving toward high pressure, high temperature, high gas production, and deep burial depths. Currently, many natural gas wellheads typically achieve production pressures exceeding 50 MPa, with daily gas production reaching hundreds of thousands or even millions of cubic meters. During fracturing operations, the fluid within the fracturing tubing typically consists of liquid and particulate matter (i.e., proppant), which together constitute the fracturing fluid system. The fracturing fluid is the core medium of the fracturing operation, primarily transmitting pressure, creating fractures, and carrying proppant into the fractures. Proppants are essential solid particles within the fracturing tubing, their primary function being to support the fractures formed by fracturing, preventing them from closing and ensuring the flow of oil and gas. Proppants are typically high-strength, fine particles such as quartz sand and ceramsite sand.

[0003] When the equipment enters high-pressure shock, the hydraulic pressure of the liquid inside the pipeline increases, but the flow rate of the liquid decreases. At this time, the particles in the liquid will precipitate, causing some proppant to remain inside the pipe. Even if the internal liquid flows again later, the proppant is closer to the inner wall of the pipe, which makes the flow rate of the proppant differ from the flow rate of the liquid, resulting in a particle-free state in the liquid inside the pipeline, affecting the subsequent prevention of crack closure. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a large-diameter high-low pressure distribution fracturing remotely controlled adjustable straight-line manifold device, comprising a bracket, two flow blocks are fixedly connected to the top of the bracket, and a flow pipe is connected between the two flow blocks;

[0005] The pressure mechanism includes a rotatable connection to the inner wall of the flow tube. When fine particles in the flow tube are precipitated, the pressure mechanism will block the space inside the flow tube.

[0006] The dispersion mechanism includes a device fixedly connected to the outer wall of the pressure mechanism and rotatably connected to collect deposited fine particles;

[0007] The regulating mechanism includes a regulating mechanism fixedly connected to the top of the bracket, which is used to control the flow diameter of the circulation block and adjust the flow pressure passing through the circulation block;

[0008] Among them, before use, ensure that the external high-pressure water can enter the circulation pipe to complete the basic transmission process.

[0009] Preferably, an end of the left circulation block away from the circulation pipe is connected to the input pipe, and an end of the right circulation block away from the circulation pipe is connected to the output pipe.

[0010] Preferably, the pressure mechanism comprises:

[0011] The rotating assembly is rotatably connected to the inner wall of the flow pipe. When the liquid in the flow pipe stops flowing or flows slowly, the rotating assembly will block most of the space inside the flow pipe.

[0012] A collecting assembly is rotatably connected to the side wall of the rotating assembly and is used to collect deposited fine particles;

[0013] When the flow speed of the liquid in the flow tube is slow, the liquid in the flow tube will flow through the gap between the rotating plate and the flow tube.

[0014] Preferably, the dispersion mechanism includes:

[0015] The pressure assembly is slidably connected to the outer wall of the collection assembly and is used to cover the through hole of the collection assembly. When fine particles in the flow tube are precipitated, the particles will be deposited on the top of the pressure assembly and the collection assembly;

[0016] An auxiliary component, which is fixedly connected to the inner wall of the pressure component and is used to drive the pressure component to reset;

[0017] When the pressure component moves upward, the end of the pressure component will contact the inner wall of the flow tube and force the pressure component to deform. At this time, the auxiliary component will accumulate mechanical power.

[0018] Preferably, the adjustment mechanism comprises:

[0019] A blocking component is fixedly connected to the outer wall of the bracket;

[0020] The blocking component is used to control the flow diameter of the circulation block and limit the flow pressure of the circulation block.

[0021] Preferably, the rotating assembly includes a plurality of rotating rods rotatably connected to the inner wall of the flow tube, a rotating plate fixedly connected to the outer wall of the plurality of rotating rods, and a fixed block fixedly connected to the side wall of the rotating plate;

[0022] Therein, a certain gap is left between the outer wall of the rotating plate and the inner wall of the flow tube, and the rotating rod is located at a position slightly above the center of the rotating plate.

[0023] Preferably, the collecting assembly includes a second rotating rod rotatably connected to the inner wall of the fixed block, a receiving plate is fixedly connected to the side wall of the second rotating rod, and a plurality of first through holes are opened on the outer wall of the receiving plate;

[0024] Among them, when the rotating plate is in a stationary state, the rotating plate will drive the receiving plate to completely fit on the bottom of the inner wall of the circulation pipe.

[0025] Preferably, the pressure assembly includes a curved slide slidably connected to the outer wall of the receiving plate, a fixed plate is fixedly connected to the side wall of the curved slide, a rotating rod three is rotatably connected to the side wall of the fixed plate, an end of the rotating rod three away from the fixed plate is rotatably connected to a support block, and a side wall of the support block is fixedly connected to the outer wall of the rotating plate;

[0026] Among them, when the rotating plate rotates upward, the rotating plate will drive the receiving plate to rotate upward. When the end of the receiving plate contacts the inside of the flow tube, as the angle between the rotating plate and the receiving plate increases, the rotating rod three will pull the arc-shaped slide, forcing the arc-shaped slide to slide along the outer wall of the receiving plate.

[0027] Preferably, the auxiliary component includes a torsion spring fixedly connected to the outer wall of the second rotating rod, the other end of the torsion spring is fixedly connected to the outer wall of the fixed block, and a plurality of second through holes are opened on the side wall of the arc-shaped slide;

[0028] When the rotating plate rotates upward, due to the influence of the torsion spring, the receiving plate will rotate upward synchronously.

[0029] Preferably, the blocking assembly includes a driving motor fixedly connected to the top of the bracket, a blocking piece fixedly connected to the side wall of the driving motor, and an end of the blocking piece away from the driving motor is fixedly connected to the inner wall of the circulation block;

[0030] When the pressure of the liquid inside the circulation pipe needs to be adjusted, the sealing member can be driven by the driving motor to seal the liquid inside the circulation block, thereby completing the basic pressure adjustment process.

[0031] The present invention has the following beneficial effects:

[0032] (1) The present invention addresses the problem that when the liquid is in a static state, small particles in the liquid will precipitate. A pressure mechanism and a dispersion mechanism are set up inside the device. As the flow rate of the liquid increases, the rotating plate will be forced to continue to rotate upward. At this time, the rotating plate will press the receiving plate to continue to rotate upward and increase the angle between the receiving plate and the rotating plate, so that the rotating plate drives the fixed plate and the arc-shaped slide plate to slide along the outer wall of the receiving plate through the rotating rod three, so that the through hole 1 and the through hole 2 are in an overlapping state. The accumulated small particles will fall down through the above overlapping gap and mix with the internal liquid again. Through the application of the above components, it is effectively guaranteed that the liquid will flow again after sedimentation, and there will still be enough small particles in the liquid.

[0033] (2) When the present invention utilizes the above-mentioned complete plate, the top of the through hole 1 will be blocked by the arc-shaped slide, so that the through hole 1 forms a concave shape with the upper part blocked and the lower part buckled. When the rotating plate drives the receiving plate to rotate upward, the receiving plate is affected by the rotation angle at the end away from the rotating plate, and the upward movement speed will be faster than the end of the receiving plate close to the fixed block. In addition, the through hole 1 and the arc-shaped slide form a downward groove. When the end of the receiving plate moves upward quickly, the liquid at the bottom of the receiving plate will be disturbed by the movement of the receiving plate, forcing the fine particles originally accumulated at the bottom of the flow tube to be dispersed due to the disturbance, and finally flow again with the water flow;

[0034] (3) The present invention utilizes the characteristic that the end of the receiving plate moves upward rapidly. When the end of the receiving plate moves upward rapidly, the contact area between the concave surface of the receiving plate and the liquid is too large, which will force the receiving plate to bear excessive pressure and form a turbulent flow at the bottom of the rotating plate. This pressure will force the angle between the rotating plate and the receiving plate to expand first, so that some of the accumulated particles are first mixed in the liquid through the gap, and the remaining part is spread out again after the subsequent receiving plate is completely rotated upward. Through the application of the above components, a small spreading range is guaranteed.

[0035] (4) The present invention utilizes the above-mentioned rotating rod to be located at a position slightly above the center of the rotating plate. When the liquid flows downstream, the rotating plate will rotate so that the rotating plate is parallel to the direction of the water flow. When underground natural gas leaks, the high-pressure natural gas will push the liquid to flow backward. At this time, the reverse-flowing liquid will push the rotating plate to rotate, forcing the rotating plate to move from the Figure 4 The status of X changes to Figure 3 state, increasing the resistance of liquid backflow inside the circulation pipe, reducing the impact force caused by liquid backflow, and effectively protecting the water pump at the input pipe end.

[0053] Before use, ensure that external high-pressure water can enter the flow tube 16 to complete the basic transmission process.

[0054] An input pipe 18 is connected through one end of the left circulation block 14 away from the circulation pipe 16 , and an output pipe 17 is connected through one end of the right circulation block 14 away from the circulation pipe 16 ;

[0055] Before use, the external pipeline is connected to the input pipe 18 to ensure that the external mixed liquid can be transmitted to the inside of the circulation pipe 16 through the input pipe 18 and finally discharged from the input pipe 18 to the outside.

[0056] The pressure mechanism 1 comprises:

[0057] The rotating assembly 11 is rotatably connected to the inner wall of the flow tube 16. When the liquid in the flow tube 16 stops flowing or flows slowly, the rotating assembly 11 will block most of the space inside the flow tube 16.

[0058] A collecting assembly 12 is rotatably connected to a side wall of the rotating assembly 11 and is used to collect deposited fine particles;

[0059] When the flow speed of the liquid in the flow tube 16 is slow, the liquid in the flow tube 16 will flow through the gap between the rotating plate 112 and the flow tube 16 .

[0060] The decentralized mechanism 2 includes:

[0061] The pressure assembly 21 is slidably connected to the outer wall of the collection assembly 12 and is used to cover the through hole of the collection assembly 12. When fine particles are precipitated inside the flow tube 16, the particles will be deposited on the top of the pressure assembly 21 and the collection assembly 12;

[0062] Auxiliary component 22, the auxiliary component 22 is fixedly connected to the inner wall of the pressure component 21, and is used to drive the pressure component 21 to reset;

[0063] When the pressure component 21 moves upward, the end of the pressure component 21 will contact the inner wall of the flow tube 16 and force the pressure component 21 to deform. At this time, the auxiliary component 22 will accumulate mechanical power.

[0064] The regulating mechanism 3 comprises:

[0065] A blocking component 31 is fixedly connected to the outer wall of the bracket 13;

[0066] The blocking component 31 is used to control the flow diameter of the circulation block 14 and limit the flow pressure of the circulation block 14 .

[0067] For example 2, please refer to Figure 2-Figure 9 The present invention is a large-diameter high-low pressure distribution fracturing remotely controlled adjustable straight-line manifold device. Based on Example 1, the rotating assembly 11 includes a plurality of rotating rods 111 rotatably connected to the inner wall of the flow tube 16, a rotating plate 112 is fixedly connected to the outer wall of the plurality of rotating rods 111, and a fixed block 113 is fixedly connected to the side wall of the rotating plate 112;

[0068] There is a certain gap between the outer wall of the rotating plate 112 and the inner wall of the flow tube 16, and the rotating rod 111 is located at a position slightly above the center of the rotating plate 112;

[0069] In order to solve the problem that small particles in the liquid will precipitate when the liquid is in a static state, a pressure mechanism 1 and a dispersion mechanism 2 are set inside the device. When the liquid is in a static state, since the rotating rod 111 is located at the upper center of the rotating plate 112, the rotating plate 112 will appear as follows: Figure 3 If the flow rate of the liquid in the circulation tube 16 is slow at this time, the liquid will flow through the gap between the rotating plate 112 and the circulation tube 16.

[0070] The collecting assembly 12 includes a second rotating rod 121 rotatably connected to the inner wall of the fixed block 113. A receiving plate 122 is fixedly connected to the side wall of the second rotating rod 121. A plurality of first through holes 123 are formed on the outer wall of the receiving plate 122.

[0071] Among them, when the rotating plate 112 is in a stationary state, the rotating plate 112 will drive the receiving plate 122 to completely fit on the bottom of the inner wall of the flow tube 16;

[0072] Taking advantage of the characteristic that the end of the receiving plate 122 moves upward quickly, when the end of the receiving plate 122 moves upward quickly, the contact area between the concave surface of the receiving plate 122 and the liquid is too large, which will force the receiving plate 122 to withstand excessive pressure and form a turbulence at the bottom of the rotating plate 112. The pressure will force the angle between the rotating plate 112 and the receiving plate 122 to expand first, so that some of the accumulated particles are first mixed in the liquid through the gap, and the remaining part is spread out again after the subsequent receiving plate 122 is completely rotated upward. Through the application of the above components, a small spreading range is guaranteed.

[0073] The pressure assembly 21 includes a curved slide 211 slidably connected to the outer wall of the receiving plate 122. A fixed plate 212 is fixedly connected to the side wall of the curved slide 211. A rotating rod 213 is rotatably connected to the side wall of the fixed plate 212. The end of the rotating rod 213 away from the fixed plate 212 is rotatably connected to a support block 214. The side wall of the support block 214 is fixedly connected to the outer wall of the rotating plate 112.

[0074] When the rotating plate 112 rotates upward, the rotating plate 112 drives the receiving plate 122 to rotate upward. When the end of the receiving plate 122 contacts the inside of the flow tube 16, as the angle between the rotating plate 112 and the receiving plate 122 increases, the rotating rod 3 213 pulls the curved slide 211, forcing the curved slide 211 to slide along the outer wall of the receiving plate 122.

[0075] When the above-mentioned complete plate is used, the top of the through hole 123 will be blocked by the curved slide 211, so that the through hole 123 forms a concave shape with the upper part blocked and the lower part locked. When the rotating plate 112 drives the receiving plate 122 to rotate upward, the receiving plate 122 is affected by the rotation angle at this time. The upward movement speed will be faster than the end of the receiving plate 122 close to the fixed block 113. In addition, the through hole 123 and the curved slide 211 form a downward groove. When the end of the receiving plate 122 moves upward quickly, the liquid at the bottom of the receiving plate 122 will be disturbed by the movement of the receiving plate 122, forcing the fine particles that have accumulated at the bottom of the circulation tube 16 to disperse due to the disturbance, and finally flow again with the water flow.

[0076] The auxiliary component 22 includes a torsion spring 221 fixedly connected to the outer wall of the second rotating rod 121. The other end of the torsion spring 221 is fixedly connected to the outer wall of the fixed block 113. A plurality of second through holes 222 are opened on the side wall of the arc-shaped slide 211.

[0077] When the rotating plate 112 rotates upward, due to the influence of the torsion spring 221, the receiving plate 122 will rotate upward synchronously.

[0078] After a long period of slow flow, the fine particles in the liquid will precipitate, and some of the precipitated particles will accumulate on the top of the complete plate. When the flow speed of the liquid in the circulation tube 16 is accelerated, the liquid will impact the rotating plate 112, forcing the rotating plate 112 to rotate around the rotating rod 111, so that the rotating plate 112 appears Figure 3 The state of G, at this time, the rotating plate 112 will drive the receiving plate 122 to rotate upward synchronously through the rotating rod 121, and during the rotation process, the side wall of the receiving plate 122 will contact the inner wall of the flow tube 16, showing as Figure 4The rotating plate 112 is in the Z state, and as the flow rate of the liquid increases, the rotating plate 112 will be forced to continue to rotate upward. At this time, the rotating plate 112 will press the receiving plate 122 to continue to rotate upward, and increase the angle between the receiving plate 122 and the rotating plate 112, so that the rotating plate 112 drives the fixed plate 212 and the arc-shaped slide plate 211 to slide along the outer wall of the receiving plate 122 through the rotating rod three 213, so that the through hole 123 and the through hole 222 are in an overlapping state, and the accumulated small particles will fall downward through the above overlapping gap and mix with the internal liquid again. Through the application of the above components, it is effectively guaranteed that the liquid will flow again after being deposited, and there are still enough fine particles in the liquid.

[0079] The blocking assembly 31 includes a drive motor 311 fixedly connected to the top of the bracket 13. A blocking member 312 is fixedly connected to the side wall of the drive motor 311. The end of the blocking member 312 away from the drive motor 311 is fixedly connected to the inner wall of the circulation block 14.

[0080] When the pressure of the liquid inside the circulation tube 16 needs to be adjusted, the blocking member 312 can be driven by the driving motor 311 to block the liquid inside the circulation block 14, thereby completing the basic pressure adjustment process.

[0081] By using the rotating rod 111 at a position slightly above the center of the rotating plate 112, when the liquid flows downstream, the rotating plate 112 will rotate so that the rotating plate 112 is parallel to the direction of the water flow. When underground natural gas leaks, the high-pressure natural gas will push the liquid to flow backward. At this time, the reverse-flowing liquid will push the rotating plate 112 to rotate, forcing the rotating plate 112 to rotate. Figure 4 The status of X changes to Figure 3 state, increases the resistance of the liquid to backflow inside the circulation pipe 16, reduces the impact force caused by the backflow of the liquid, and effectively protects the water pump at the end of the input pipe 18.

[0082] A specific application of this embodiment is as follows: before use, the present invention is connected to the external pipeline and the input pipe 18 to ensure that the external mixed liquid can be transferred to the interior of the flow pipe 16 through the input pipe 18 and finally discharged from the input pipe 18;

[0083] In order to solve the problem that small particles in the liquid will precipitate when the liquid is in a static state, a pressure mechanism 1 and a dispersion mechanism 2 are set inside the device. When the liquid is in a static state, since the rotating rod 111 is located at the upper center of the rotating plate 112, the rotating plate 112 will appear as follows: Figure 3 If the liquid flow rate in the flow tube 16 is slow at this time, the liquid will flow through the gap between the rotating plate 112 and the flow tube 16;

[0084] At this time, the arc-shaped slide plate 211 blocks the through hole 123, so that the arc-shaped slide plate 211 and the receiving plate 122 form a complete plate;

[0085] After a long period of slow flow, the fine particles in the liquid will precipitate, and some of the precipitated particles will accumulate on the top of the complete plate. When the flow speed of the liquid in the flow tube 16 is accelerated, the liquid will impact the rotating plate 112, forcing the rotating plate 112 to rotate around the rotating rod 111, causing the rotating plate 112 to appear Figure 3 The state of G, at this time, the rotating plate 112 will drive the receiving plate 122 to rotate upward synchronously through the rotating rod 121, and during the rotation process, the side wall of the receiving plate 122 will contact the inner wall of the flow tube 16, showing as Figure 4 The rotating plate 112 is in the Z state, and as the flow rate of the liquid increases, the rotating plate 112 will be forced to continue to rotate upward. At this time, the rotating plate 112 will press the receiving plate 122 to continue to rotate upward, and increase the angle between the receiving plate 122 and the rotating plate 112, so that the rotating plate 112 drives the fixed plate 212 and the arc-shaped slide plate 211 to slide along the outer wall of the receiving plate 122 through the rotating rod three 213, so that the through hole 123 and the through hole 222 are in an overlapping state, and the accumulated small particles will fall downward through the above overlapping gap and mix with the internal liquid again. Through the application of the above components, it is effectively guaranteed that the liquid will flow again after being deposited, and there are still enough fine particles in the liquid.

[0086] When the above-mentioned complete plate is used, the top of the through hole 123 will be blocked by the curved slide plate 211, so that the through hole 123 forms a concave shape with the upper part blocked and the lower part locked. When the rotating plate 112 drives the receiving plate 122 to rotate upward, the receiving plate 122, which is away from the rotating plate 112, is affected by the rotation angle and moves upward faster than the receiving plate 122, which is close to the fixed block 113. In addition, the through hole 123 and the curved slide plate 211 form a downward groove. When the end of the receiving plate 122 moves upward quickly, the liquid at the bottom of the receiving plate 122 will be disturbed by the movement of the receiving plate 122, forcing the fine particles originally accumulated at the bottom of the flow tube 16 to be dispersed due to the disturbance, and finally flow again with the water flow.

[0087] Taking advantage of the characteristic that the end of the receiving plate 122 moves upward quickly, when the end of the receiving plate 122 moves upward quickly, the contact area between the concave surface of the receiving plate 122 and the liquid is too large, which will force the receiving plate 122 to bear excessive pressure and form a turbulence at the bottom of the rotating plate 112. The pressure will force the angle between the rotating plate 112 and the receiving plate 122 to expand first, so that some of the accumulated particles are first mixed in the liquid through the gap, and the remaining part is spread outward again after the subsequent receiving plate 122 is completely rotated upward. Through the application of the above components, a small spreading range is guaranteed.

[0088] By using the rotating rod 111 at a position slightly above the center of the rotating plate 112, when the liquid flows downstream, the rotating plate 112 will rotate so that the rotating plate 112 is parallel to the direction of the water flow. When underground natural gas leaks, the high-pressure natural gas will push the liquid to flow backward. At this time, the reverse-flowing liquid will push the rotating plate 112 to rotate, forcing the rotating plate 112 to rotate. Figure 4 The status of X changes to Figure 3 state, increases the resistance of the liquid to backflow inside the circulation pipe 16, reduces the impact force caused by the backflow of the liquid, and effectively protects the water pump at the end of the input pipe 18.
