Description

Technical Field

[0001] The invention relates to the technical field of oilfield exploitation, and in particular to a device for processing sediments in oilfield produced materials. Background Art

[0002] As the development of oil fields progresses, especially in the middle and late stages, a significant challenge encountered in the oil production process is that the composition of the produced material becomes extremely complex. In addition to the traditional three-phase medium of crude oil, water and gas, it also contains wax, asphaltene, sand, scale layers (such as carbonates and sulfates) and microbial metabolites and other sediments. These complex components not only affect the quality of oil, but also put forward higher requirements for subsequent processing technology.

[0003] At present, one of the main methods for processing these oilfield products is to use a mud pump to extract the products containing various impurities and transport them to the filter press through a pipeline for solid-liquid separation. Specifically, plate and frame filter presses and diaphragm filter presses are widely used in such occasions to press solid particles into filter cakes. However, this type of equipment has an obvious defect in the actual operation process: when a batch of produced materials is being processed in the filter press, the mud pump must be suspended during this period because it is necessary to wait for the batch to be completely processed before receiving the next batch of materials. Due to this intermittent working mode, the continuous operation capacity and efficiency of the entire system will be seriously affected. Although belt filter presses and mud vibrating screens can solve the problem of continuous operation to a certain extent, they perform poorly in terms of solid-liquid separation, especially the high water content of the filtered solid particles, which not only increases the subsequent processing costs, but also may have adverse effects on the environment. In addition, no matter what type of filter press, like the mud pump, it is usually large in size, which not only increases the difficulty of transporting the equipment, but also means that more preparation work is required during on-site installation and commissioning, including complex pipeline connections. Summary of the invention

[0013] Compared with the prior art, the present invention has the following advantages: 1.

When the first piston moves left and right, the liquid can be effectively discharged through the filter cloth, and the solid particles are compressed into filter cakes, thereby avoiding the problem that the traditional filter press must wait for completion before receiving new materials during batch processing, which can greatly improve the continuity and work efficiency of the system.

[0014] 2. The present invention ensures that solid particles are effectively compressed under high pressure conditions and reduces the moisture content in the filter cake through the coordinated work of the first piston, the second piston and the blocking assembly. In addition, when the predetermined pressure is reached, the control system will trigger the cylinder to separate the mounting cylinder from the connecting cylinder.

[0015] 3. The present invention adopts the design of casing, brushless motor and stirring frame, so that the pumping pipe can enter through the water inlet hole when extracting oil field produced materials. At the same time, the brushless motor drives the stirring frame to rotate, which can prevent the produced materials from accumulating and clogging the pipeline, thereby ensuring the smooth flow of the fluid. In addition, through the cooperation of the air pump, connecting pipe, arc plate, arc pipe and nozzle, each time the pressure plate pushes out the filter cake, compressed air can be used to clean the surface of the pressure plate to ensure that the filter cake falls smoothly, thereby improving the operational flexibility and maintenance convenience of the entire equipment.

[0035] like Figure 4-Figure 6As shown, the driving assembly includes a driving motor 13, a rotating plate 14, a connecting plate 15, a worm 16, a worm wheel 17 and a short rod 18. The driving motor 13 is symmetrically installed in the middle of the upper part of the frame 1, and the rotating plate 14 is symmetrically connected to the upper right side of the frame 1 for rotation. The right part of the sliding tube 7 is connected to the connecting plate 15, and vertical grooves 1501 are opened on the front and rear sides of the connecting plate 15.

The two rotating plates 14 are connected to the side close to the connecting plate 15 with short rods 18, and the two short rods 18 are respectively embedded in and slide along the vertical grooves 1501 on both sides of the connecting plate 15.

[0036] like Figure 7-Figure 9 As shown, the blocking assembly includes a cylinder 19, a mounting cylinder 20, a fixing plate 21, a sliding rod 22, a pressing plate 23, a connecting spring 24, a control switch 25 and a limiting mechanism. The cylinder 19 is connected to both the front and rear sides of the connecting cylinder 3. The mounting cylinder 20 is connected between the telescopic rods of the two cylinders 19. The mounting cylinder 20 is located on the left side of the connecting cylinder 3, and the inner and outer diameters of the mounting cylinder 20 are consistent with the inner and outer diameters of the connecting cylinder 3. The right side of the mounting cylinder 20 is in close contact with the left side of the connecting cylinder 3 and ensures sealing. The fixing plate 21 is connected to the left side of the inner wall of the mounting cylinder 20, and the sliding rod 22 is slidably connected to the middle part of the fixing plate 21. The pressing plate 23 is connected to the right end of the sliding rod 22, and the pressing plate 23 is close to the inner wall of the mounting cylinder 20. A connecting spring 24 is wound around the outside of the sliding rod 22, and the two ends of the connecting spring 24 are respectively connected A control switch 25 is installed on the upper right side of the connecting tube 3, connecting the right side of the fixed plate 21 and the left side of the pressure plate 23. The limiting mechanism is used to limit the sliding rod 22; the limiting mechanism includes a circular plate 27, a return spring 28 and a limiting rod 29. Four limiting grooves 26 are symmetrically opened on the sliding rod 22. The front, back, upper and lower sides of the fixed plate 21 are connected with circular plates 27. The four circular plates 27 are connected to the sides close to the sliding rod 22. The front, back, upper and lower sides of the fixed plate 21 are slidably connected with the limiting rod 29. The limiting rod 29 corresponds to the return spring 28 one by one. The end of the limiting rod 29 away from the sliding rod 22 is connected to the end of the return spring 28 corresponding to it. The end of the limiting rod 29 close to the sliding rod 22 is an arc surface and can be stuck in the corresponding limiting groove 26.

[0037] Initially, the first one-way valve 5 and the second one-way valve 11 are both in a closed state, and the first piston 9 is in contact with the pressure plate 23; first, the equipment is transported to the designated position, and then the right end of the water pumping pipe 6 and the right end of the hose 8 are placed at the designated positions respectively, and then the driving motor 13 is controlled by the controller 2 to start working, the driving motor 13 can drive the worm 16 to rotate, the worm 16 can drive the worm gear 17 to rotate, and the worm gear 17 can drive the rotating plate 14 to rotate, and the rotating plate 14 can drive the connecting plate 15 to reciprocate left and right through the cooperation of the short rod 18 and the vertical groove 1501, and the connecting plate 15 can drive the sliding tube 7 and the first piston 9 to reciprocate left and right. When the first piston 9 moves to the right, the first piston 9 will separate from the pressure plate 23, and the first piston 9 will squeeze the air between the first piston 9 and the baffle 4. At this time, the air between the first piston 9 and the baffle 4 will push the valve disc of the second one-way valve 11 to open, so that the air between the first piston 9 and the baffle 4 can pass through the first one-way valve 11. The second one-way valve 11 flows to between the first piston 9 and the pressure plate 23, while the first one-way valve 5 remains in a closed state until the right side of the first piston 9 contacts the left side of the baffle 4. At this time, all the air between the first piston 9 and the baffle 4 is discharged, and the second one-way valve 11 will resume the closed state. Then the first piston 9 will move to the left, and the first piston 9 will squeeze the air between the first piston 9 and the pressure plate 23, so that the air is discharged through the filter cloth 12, the sliding tube 7 and the hose 8. At the same time, a negative pressure will be formed between the first piston 9 and the baffle 4, and the valve disc of the first one-way valve 5 will open due to the pressure. The second one-way valve 11 remains in a closed state, so that the oilfield produced material can be extracted through the pumping pipe 6. The oilfield produced material will enter between the first piston 9 and the baffle 4 through the first one-way valve 5. When the first piston 9 contacts the pressure plate 23 again, the oilfield produced material no longer enters between the first piston 9 and the baffle 4, and the first one-way valve 5 will resume the closed state.Similarly, when the first piston 9 moves to the right again, the oilfield produced material between the first piston 9 and the baffle 4 will enter between the first piston 9 and the pressure plate 23 through the second one-way valve 11. When the first piston 9 moves to the left again, a new batch of oilfield produced material will enter between the first piston 9 and the baffle 4. At the same time, the first piston 9 cooperates with the pressure plate 23 to squeeze the oilfield produced material between the first piston 9 and the pressure plate 23. The filter cloth 12 plays a filtering role, so that the liquid in the oilfield produced material can be filtered out. The solid particles in the oilfield produced material are discharged through the filter cloth 12, the sliding pipe 7 and the hose 8, and the solid particles in the oilfield produced material are pressed into filter cakes by the first piston 9 and the pressure plate 23. When the solid particles in the oilfield produced material can no longer be compressed, the first piston 9 can push the pressure plate 23 to move to the left and retract into the inside of the installation cylinder 20 through the filter cake, and the pressure plate 23 can drive the sliding rod 22 to move to the left, the connecting spring 24 is compressed, and the sliding rod 22 can squeeze the limiting rod 29 through the limiting groove 26 to move away from the sliding rod 22. The return spring 28 is compressed, so that the limit rod 29 is disengaged from the limit groove 26, and then the connecting plate 15 will contact the control switch 25, and the control switch 25 sends a signal. The controller 2 receives the signal and controls the cylinder 19 to drive the installation tube 20 to move to the left and disengage from the connecting tube 3. At this time, the connecting spring 24 will return to its original state, driving the pressure plate 23 and the sliding rod 22 to move to the right and reset. The pressure plate 23 can push the filter cake to the right, so that the filter cake falls down to the inclined surface on the left side of the frame 1 for discharging, and the return spring 28 will return to its original state, driving the limit rod 29 to move and reset in the direction close to the sliding rod 22 and re-stuck in the limit groove 26 to limit the sliding rod 22, and then the connecting plate 15 will move to the right and separate from the control switch 25. The control switch 25 sends a signal. The controller 2 receives the signal and controls the cylinder 19 to drive the installation tube 20 to move to the right and reset, so that the installation tube 20 contacts the connecting tube 3 again. In this way, the oil field produced material can be extracted and the solid-liquid separation can be carried out at the same time, with high continuity and work efficiency. ;

[0038] like Figure 3 and Fig.10 As shown, a filter block 30 is also included. The inner wall of the through hole 10 is connected to the filter block 30. The left side of the filter block 30 contacts the right side of the filter cloth 12, and the filter hole diameter of the filter block 30 is larger than the filter hole diameter of the filter cloth 12. The filter block 30 is used to support the filter cloth 12 to prevent the filter cloth 12 from being damaged due to excessive pressure.

[0039] When the connecting plate 15 moves to the right and separates from the control switch 25, the oilfield produced in the connecting cylinder 3 will immediately squeeze the valve flap of the second one-way valve 11 open. Since it takes a certain amount of time for the cylinder 19 to control the installation cylinder 20 to move and close, the oilfield produced may directly fall down through the gap between the first piston 9 and the pressure plate 23. Therefore, a buffer component is designed; Figure 3 , Fig.11 and Fig.12 As shown, it also includes a magnet 31, a second piston 32 and a telescopic tube 33. Four magnets 31 are connected to the left side of the baffle 4 at circumferential intervals. The second piston 32 is slidably connected to the inner wall of the connecting tube 3. The second piston 32 is located between the baffle 4 and the first piston 9, and the sliding tube 7 slides through the middle of the second piston 32. The telescopic tube 33 is symmetrically connected between the second piston 32 and the first piston 9. The left ends of the two telescopic tubes 33 are respectively aligned with the two second one-way valves 11. Circular holes 34 are opened on the upper and lower sides of the second piston 32. The right ends of the two telescopic tubes 33 are respectively aligned with the two circular holes 34. An air flow channel 35 is opened on the upper side of the sliding tube 7. A notch 36 is opened on the upper right side of the first piston 9, and the notch 36 is connected to the air flow channel 35, so that the space between the second piston 32 and the first piston 9 can be connected to the outside through the notch 36 and the air flow channel 35.

[0040] When the connecting plate 15 moves to the right and separates from the control switch 25, the first piston 9 will move to the right synchronously with the connecting plate 15. At this time, the second piston 32 remains stationary, the telescopic tube 33 will be shortened, and the air between the first piston 9 and the second piston 32 will be squeezed and discharged outward through the gap 36 and the air flow channel 35. Since the second piston 32 remains stationary, the oilfield produced material in the connecting cylinder 3 is not subjected to pressure, and the oilfield produced material will not temporarily squeeze the valve disc of the second one-way valve 11 open, thereby ensuring that the installation cylinder 20 has enough time to close. When the first piston 9 contacts the second piston 32, the first piston 9 will push the second piston 32 to move to the right synchronously, so that the connecting cylinder 3 The oilfield produced material inside can be pressurized to enter the circular hole 34 and the telescopic tube 33, and squeeze the valve disc of the second one-way valve 11 to open, completing the transfer of the oilfield produced material. When the second piston 32 contacts the magnet 31, the magnet 31 can attract the second piston 32 through magnetic force. When the first piston 9 moves to the left, the second piston 32 remains stationary, and the telescopic tube 33 will stretch and recover. The outside air can enter between the first piston 9 and the second piston 32 through the air flow channel 35 and the gap 36, providing time for the next closing of the installation cylinder 20. When the telescopic tube 33 can no longer be extended, the first piston 9 will pull the second piston 32 to move synchronously to the left through the telescopic tube 33, so that the second piston 32 is separated from the magnet 31.

[0041] like Fig.13 and Fig.14As shown, it also includes an air pump 37, a connecting pipe 3701, an arc plate 38, an arc pipe 39 and a nozzle 40. The air pump 37 is installed on the right rear side of the top of the frame 1, and the air outlet of the air pump 37 is connected to the connecting pipe 3701 and maintained in communication. The arc plate 38 is connected to the right side of the top of the installation cylinder 20, and the arc pipe 39 is connected to the right side of the arc plate 38. The left end of the connecting pipe 3701 is connected to the arc pipe 39 and maintained in communication, and a plurality of nozzles 40 are evenly spaced and installed at the bottom of the arc pipe 39; the air pump 37 is controlled by the controller 2 to start working, and the air pump 37 can deliver compressed air to the nozzle 40 through the connecting pipe 3701 and the arc pipe 39. Whenever the pressing plate 23 pushes the filter cake to the right, the nozzle 40 can spray the compressed air downward to ensure that the filter cake can fall down quickly for discharge, and prevent the filter cake from sticking to the side of the pressing plate 23.

[0042] like Fig.15 and Fig.16 As shown, it also includes a casing 41, a brushless motor 42 and a stirring frame 43. The right end of the water pumping pipe 6 is connected to the casing 41, and the casing 41 is circumferentially spaced with water inlet holes 4101. The brushless motor 42 is installed inside the casing 41, and the stirring frame 43 is installed on the brushless motor 42. When the water pumping pipe 6 extracts oilfield produced materials, the oilfield produced materials can enter the water pumping pipe 6 through the water inlet hole 4101 and the casing 41, and at the same time, the brushless motor 42 can be controlled by the controller 2 to drive the stirring frame 43 to rotate. The stirring frame 43 can stir the oilfield produced materials to make the oilfield produced materials flow, thereby preventing the oilfield produced materials from being deposited.

[0043] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
