Technical Field

[0001] This utility model relates to the field of oilfield injection and production technology, and in particular to a novel oilfield injection and production device. Background Technology

[0002] An oilfield is an area with abundant underground petroleum resources. It is the core resource base of the petroleum industry. Petroleum, as an important fossil energy source, is widely used in many fields such as fuel and chemical raw materials, and plays a vital role in modern industrial and economic development. Oilfield water injection uses water injection equipment to inject water of the required quality from the injection well into the oil layer to maintain the oil layer pressure. This process is called oilfield water injection. Oilfield water injection is one of the important means to replenish the formation with energy and improve the oilfield recovery rate during the oilfield development process.

[0003] In existing technologies, existing oilfield injection and production devices inject water into the oilfield through pipelines using water pumps. However, these devices cannot shut down the pipelines or regulate the flow rate in case of emergencies, leading to high-pressure liquid leaks, environmental pollution, or equipment damage, which affects the overall development of the oilfield. Therefore, it is necessary to develop a new type of oilfield injection and production device to solve the above problems. Utility Model Content

[0004] To overcome the problem that existing oilfield injection and production devices inject water into the oilfield through pipelines using pumps, but cannot shut down the pipelines or adjust the flow rate in case of emergencies, thus affecting the overall development effect of the oilfield.

[0005] The technical solution of this utility model is as follows: A novel oilfield injection and production device includes a top plate, a water injection rigid pipe, and a stabilizing component. A stabilizing component to improve the stability of the top plate is provided at its bottom. A support plate is fixedly connected to the bottom of the top plate, and a bottom plate is fixedly connected to the bottom of the support plate. A water injection rigid pipe is fixedly connected inside the top plate and the bottom plate. A water pump is fixedly connected to the top of the top plate, and an external pipe is fixedly connected to the rear end of the water pump. A connecting pipe is fixedly connected between the water pump and the water injection rigid pipe. A PLC controller is fixedly connected to the water pump and electrically connected to the PLC controller. The water injection rigid pipe... A pressure sensor is fixedly connected and electrically connected to the PLC controller. A second fixed frame is fixedly connected to the water injection pipe.

A first fixed frame is fixedly connected to the water injection pipe, and the rotating rod is rotatably connected inside the first fixed frame. An adjusting plate is fixedly connected to the rotating rod by bolts, and a sealing ring is fixedly connected to the outside of the adjusting plate. A mounting bracket is fixedly connected to the rear end of the second fixed frame, and a motor is fixedly connected to the rear end of the mounting bracket. The motor is electrically connected to the PLC controller.

[0006] Preferably, two support plates are provided, which are symmetrically distributed between the top plate and the bottom plate.

[0007] Preferably, a worm is fixedly connected to the output end of the motor, a semicircular block is fixedly connected to the rear end of the mounting bracket, the worm is rotatably connected inside the semicircular block, a worm wheel is fixedly connected to the rotating rod, and the worm meshes with the outside of the worm wheel.

[0008] Preferably, two sets of semicircular blocks are provided, and the two sets of semicircular blocks are symmetrically distributed at the rear end of the mounting frame.

[0009] Preferably, the worm gear is provided with two stops, which are symmetrically and fixedly connected to the worm gear.

[0011] Preferably, the support plate has a matching groove at the corresponding position of the pressing plate, and the pressing plate slides within the groove of the support plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to existing oilfield injection and production equipment that uses pumps to inject water into the oilfield through pipelines and a PLC controller to start a motor that drives a rotating rod to rotate an adjusting plate, this new equipment improves the efficiency of injection and production. It also enhances the ease of adjusting the flow rate within the injection pipe by adjusting the angle of the adjusting plate, thereby improving the overall development effect of the oilfield and enhancing the practicality of the equipment. This avoids the problem of being unable to close or adjust the flow rate in the pipeline in case of emergencies, which could negatively impact the overall development of the oilfield.

[0014] 2. Insert the water injection hard pipe into the water injection well by moving the placement frame. Then, rotate the rotating disc to drive the threaded rod to rotate, which in turn drives the pressing plate to move downward. The moving pressing plate drives the rubber ring to squeeze the air bag. Then, the compressed air bag deforms and causes the rubber ring to extend outward, making it easier to contact the external fixing parts. This improves the stability of the top plate and prevents the device from shaking during injection and extraction, thus improving the stability of the injection and extraction process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment: a novel oilfield injection and production device, including a top plate 1, a water injection rigid pipe 21, and a stabilizing component. A stabilizing component to improve the stability of the top plate 1 is provided at the bottom of the top plate 1. A support plate 4 is fixedly connected to the bottom of the top plate 1, and a bottom plate 5 is fixedly connected to the bottom of the support plate 4. The water injection rigid pipe 21 is fixedly connected inside the top plate 1 and the bottom plate 5. A water pump 22 is fixedly connected to the top of the top plate 1. An external pipe 23 is fixedly connected to the rear end of the water pump 22. A connecting pipe 24 is fixedly connected between the water pump 22 and the water injection rigid pipe 21. A PLC controller 25 is fixedly connected to the water pump 22 and electrically connected to the PLC controller 25. A pressure sensor 26 is fixedly connected to the water injection rigid pipe 21. The pressure sensor 26 and PLC controller 25 are common technical means in this field, so they will not be described in detail. The pressure sensor 26 is electrically connected to the PLC controller 25. A second fixed frame 216 is fixedly connected to the water injection pipe 21. A rotating rod 29 is rotatably connected inside the second fixed frame 216. The rotating rod 29 is rotatably connected inside the water injection pipe 21. A first fixed frame 28 is fixedly connected to the water injection pipe 21. The rotating rod 29 is rotatably connected inside the first fixed frame 28. An adjusting plate 214 is fixedly connected to the rotating rod 29 by bolts. A sealing ring 215 is fixedly connected to the outside of the adjusting plate 214. A mounting bracket 27 is fixedly connected to the rear end of the second fixed frame 216. A motor 213 is fixedly connected to the rear end of the mounting bracket 27. 13 is electrically connected to PLC controller 25. PLC controller 25 controls motor 213 to start, which drives rotating rod 29 to rotate adjusting plate 214. By adjusting the angle of adjusting plate 214, the flow rate inside water injection hard pipe 21 is adjusted and closed. Sealing ring 215 improves the sealing performance of adjusting plate 214 when closing water injection hard pipe 21, increasing injection efficiency and improving the convenience of adjusting the flow rate inside water injection hard pipe 21 during injection. The stability component inserts water injection hard pipe 21 into water injection well through moving placement frame 31, and then rotates rotating disk 36 to drive threaded rod 35 to rotate, which drives pressing plate 34 to move downward. The moving pressing plate 34 drives rubber ring. 32 compresses the airbag 33, causing the compressed airbag 33 to deform and extend the rubber ring 32 outward, facilitating contact with external fixing components and improving the stability of the top plate 1. This prevents the device from shaking during injection and improves stability during injection. Two support plates 4 are symmetrically distributed between the top plate 1 and the bottom plate 5, enhancing the support stability and practicality of the device. A worm gear 212 is fixedly connected to the output end of the motor 213. A semi-circular block 211 is fixedly connected to the rear end of the mounting bracket 27. The worm gear 212 is rotatably connected inside the semi-circular block 211. A worm wheel 210 is fixedly connected to the rotating rod 29, with the worm gear 212 meshing with the outside of the worm wheel 210.When it is necessary to close or adjust the flow rate inside the water injection pipe 21, the PLC controller 25 controls the motor 213 to start, which drives the rotating rod 29 to rotate the adjusting plate 214. By adjusting the angle of the adjusting plate 214, the flow rate inside the water injection pipe 21 is regulated and closed. The sealing ring 215 improves the sealing performance of the adjusting plate 214 when closing the water injection pipe 21, increasing the efficiency of injection and production, improving the convenience of adjusting the flow rate inside the water injection pipe 21 during injection and production, and enhancing the overall oilfield performance. To improve the practicality of the device, two sets of semicircular blocks 211 are symmetrically distributed at the rear end of the mounting frame 27, enhancing the stability of the worm gear 212's rotation. The self-locking function of the worm gear 212 and worm wheel 210 improves the closure and regulation of the internal flow velocity in the water injection pipe 21, further enhancing the device's practicality. Two stops are symmetrically fixed to the worm wheel 210, limiting the rotational stroke of the adjusting plate 214 to only 180 degrees, thus improving the device's stability.

[0024] Please see Figure 2 , Figure 6 In this embodiment, the stabilizing component includes a placement frame 31, which is fixedly connected to the top of the base plate 5. A rubber ring 32 is disposed inside the placement frame 31, and an airbag 33 is disposed inside the rubber ring 32. A pressing plate 34 is slidably connected inside the support plate 4. A threaded rod 35 is threadedly connected inside the top plate 1, and the threaded rod 35 is rotatably connected to the inside of the pressing plate 34. A rotating disk 36 is fixedly connected to the top of the threaded rod 35. The stabilizing component inserts the water injection pipe 21 into the water injection well by moving the placement frame 31, and then rotates the rotating disk 36 to drive the threaded rod 35 to rotate, thereby driving the pressing plate 34. The plate 34 moves downward, and the moving pressing plate 34 drives the rubber ring 32 to squeeze the airbag 33. Then, the compressed airbag 33 deforms, causing the rubber ring 32 to extend outward, making it easier to contact the external fixing parts, thereby improving the stability of the top plate 1 and preventing the device from shaking during injection. The support plate 4 has a matching groove at the corresponding position of the pressing plate 34. The pressing plate 34 slides in the groove of the support plate 4, which limits the movement of the pressing plate 34 and improves the working stability of the device.

[0025] During operation, the water injection pipe 21 is inserted into the water injection well by moving the placement frame 31. Then, the rotating disc 36 drives the threaded rod 35 to rotate, causing the pressing plate 34 to move downwards. The moving pressing plate 34 causes the rubber ring 32 to compress the air bladder 33. The compressed air bladder 33 deforms, causing the rubber ring 32 to extend outwards, facilitating contact with external fasteners and improving the stability of the top plate 1. Then, the pressure sensor 26 is activated, and the working pressure sensor 26 detects the pressure data inside the water injection pipe 21. The PLC controller 25 receives the data from the pressure sensor 26. When the pressure data detected by the pressure sensor 26 is lower than the threshold, the PLC controller 25 controls the water pump 22 to start. The started water pump 22 is connected to the external pipe 2. 3. Water from the outside is drawn in and then discharged into the interior of the water injection hard pipe 21 through the connecting pipe 24 to pressurize the interior of the water injection hard pipe 21. When it is necessary to close the interior of the water injection hard pipe 21 or adjust the flow rate inside the water injection hard pipe 21, the motor 213 is started by the PLC controller 25. The motor 213 drives the worm gear 212 to rotate inside the two semi-circular blocks 211, so that it meshes with the worm gear 210, which drives the rotating rod 29 to rotate inside the second fixed frame 216, the water injection hard pipe 21, and the first fixed frame 28, which controls the adjustment plate 214 to rotate. By adjusting the angle of the adjustment plate 214, the flow rate inside the water injection hard pipe 21 is adjusted and closed. The sealing ring 215 improves the sealing performance of the adjustment plate 214 when the interior of the water injection hard pipe 21 is closed.

[0026] Through the above steps, the PLC controller 25 controls the motor 213 to start, which drives the rotating rod 29 to rotate the adjusting plate 214. By adjusting the angle of the adjusting plate 214, the flow rate inside the water injection hard pipe 21 can be adjusted and closed, thereby solving the problem that the pipeline cannot be closed and the flow rate inside the pipeline can not be adjusted according to the emergency, which affects the overall development effect of the oilfield.
