Description

Technical Field

[0001] This utility model relates to the technical field of water flow regulation structure of water injection device for oilfield development, and in particular to a water injection device for oilfield development that facilitates the regulation of water flow. Background Technology

[0002] In the process of oilfield development, water injection is one of the key links to enhance crude oil recovery. As the core equipment of water injection, the water injection device is used 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.

[0003] In the process of using water injection devices in oil fields, most existing water injection devices adopt manual valves or simple mechanical adjustment mechanisms. These mechanisms often have problems such as complicated operation, limited adjustment range, and low adjustment accuracy during the adjustment process.

[0004] Therefore, in view of the above-mentioned problem of inconvenient water flow control, this utility model discloses a water injection device for oilfield development that can easily adjust water flow. When the water flow adjustment structure of the water injection device for oilfield development is in use, the inner diameter of the adjustment pipe can be adjusted to open or close or be blocked during the opening or closing of the adjustment arc plates on both sides, so as to achieve convenient and precise control of water flow, which greatly improves the flexibility and efficiency of water injection operations in oilfield development. Utility Model Content

[0005] In order to overcome the problems of inconvenient operation and insufficient adjustment accuracy of traditional water injection devices for oilfield development, which are easy to adjust water flow, it is necessary to improve them. These problems not only increase the labor intensity of operators, but may also affect the overall effect of water injection operations due to unstable water flow, thus negatively impacting crude oil recovery.

[0006] The technical solution of this utility model is as follows: a water injection device for oilfield development that facilitates the adjustment of water flow, comprising an adjusting pipe, a fixed box, an adjusting wheel, an adjusting shaft, an adjusting gear, a guide rod, a guide block, a double-sided toothed plate, a rotating shaft, a rotating gear, a sealing ring, and an adjusting arc plate; a fixed box is fixedly installed on the upper surface of the adjusting pipe, an adjusting shaft is installed inside the fixed box, an adjusting wheel is installed at the upper end of the adjusting shaft, an adjusting gear is installed at the lower end of the adjusting shaft, a guide rod is fixedly installed inside the fixed box, a guide block is installed on the side wall of the guide rod, a double-sided toothed plate is fixedly installed on the bottom wall of the guide block, two sets of rotating gears are installed on both sides of the double-sided toothed plate, two sets of rotating shafts are installed inside the adjusting pipe, the rotating gears are installed at the upper ends of the rotating shafts, two sets of adjusting arc plates are installed inside the adjusting pipe, one side of the adjusting arc plate is fixedly connected to the side wall of the rotating shaft, and a sealing ring is fixedly installed inside the adjusting pipe.

[0007] Preferably, during the use of the water flow regulation structure in the oilfield development water injection device, firstly, the operator rotates the regulating wheel, which in turn drives the regulating gear to rotate via the regulating shaft. Since the regulating gear meshes with the double-sided toothed plate, it can drive the double-sided toothed plate to move parallel. During this process, the double-sided toothed plate can drive the guide block to move smoothly via the guide rod. Because the rotating gears on both sides mesh with the sides of the double-sided toothed plate, as the double-sided toothed plate moves, it can drive the rotating gears on both sides to rotate in opposite directions. These rotating gears can then drive the two regulating arc plates on both sides to unfold in opposite directions via the rotating shafts on both sides. As the two adjusting arc plates unfold or close, the inner diameter of the adjusting pipe can be adjusted to open or close, thus allowing for convenient adjustment of the water flow rate. When the two adjusting arc plates are fully unfolded and tightly fitted to the built-in sealing ring, the inner diameter of the adjusting pipe is completely blocked, and the water flow is completely cut off. This design not only ensures the accuracy of adjustment but also greatly enhances the sealing performance of the device. In summary, this utility model, through a precise mechanical linkage design, allows operators to easily and accurately control the water flow rate by simply rotating the adjusting wheel, greatly improving the flexibility and efficiency of water injection operations in oilfield development.

[0008] Preferably, the adjusting shaft is rotatably connected to the fixed box, the guide block is slidably connected to the guide rod, the adjusting gear meshes with one side of the double-sided toothed plate, both sets of rotating gears mesh with both sides of the double-sided toothed plate, and both ends of the rotating shaft are rotatably connected to the inner wall of the adjusting tube.

[0009] Preferably, both ends of the regulating pipe are provided with two sets of mounting flanges, and the side walls of the mounting flanges are provided with mounting holes, and multiple sets of mounting holes are provided.

[0010] Preferably, a water inlet pipe is provided at the right end of the regulating pipe, and a connecting flange is provided at the left end of the water inlet pipe. The left wall of the connecting flange abuts against the right wall of the right end mounting flange, and multiple sets of connecting holes are provided on the side wall of the connecting flange.

[0011] Preferably, a connecting bolt is provided inside the connecting hole, and a connecting nut is provided on the side wall of the connecting bolt, with the connecting nut being threadedly connected to the connecting bolt.

[0012] Preferably, the left end of the regulating pipe is provided with a water outlet pipe, and the right end of the water outlet pipe is provided with a fixed flange. The right wall of the fixed flange is in contact with the left wall of the left end mounting flange, and multiple sets of fixing holes are opened on the side wall of the fixed flange.

[0013] Preferably, a fixing bolt is provided inside the fixing hole, and a fixing nut is provided on the side wall of the fixing bolt, with the fixing nut being threadedly connected to the fixing bolt.

[0014] The beneficial effects of this utility model are: When the water flow regulation structure of the oilfield development water injection device is in use, firstly, the operator rotates the regulating wheel, which drives the regulating gear to rotate via the regulating shaft. Since the regulating gear meshes with the double-sided toothed plate, it can drive the double-sided toothed plate to move parallel. During this process, the double-sided toothed plate can drive the guide block to move smoothly via the guide rod. Because the rotating gears on both sides mesh with the two sides of the double-sided toothed plate, as the double-sided toothed plate moves, it can drive the rotating gears on both sides to rotate in opposite directions. These rotating gears can then drive the two regulating arc plates on both sides to unfold in opposite directions via the rotating shafts on both sides. During the opening or closing of the side adjustment arc plates, the inner diameter of the adjustment pipe can be adjusted to open or close, thereby facilitating the adjustment of the water flow rate. When both adjustment arc plates are fully opened and tightly fitted to the built-in sealing ring, the inner diameter of the adjustment pipe is completely blocked, and the water flow is completely cut off. This design not only ensures the accuracy of adjustment but also greatly enhances the sealing performance of the device. In summary, this utility model, through a precise mechanical linkage design, allows operators to easily and accurately control the water flow rate by simply rotating the adjustment wheel, greatly improving the flexibility and efficiency of water injection operations in oilfield development.

[0023] Please see Figure 1 and Figure 2A connecting bolt 19 is provided inside the connecting hole 18, and a connecting nut 20 is provided on the side wall of the connecting bolt 19. The connecting nut 20 is threadedly connected to the connecting bolt 19. Multiple sets of connecting bolts 19 are passed through the interiors of multiple sets of connecting holes 18 and mounting holes 15, and then the connecting nut 20 is rotated and tightened to one end of the connecting bolt 19, thereby securing the right end of the regulating pipe 1 to the left end of the inlet pipe 16. A water outlet pipe 21 is provided at the left end of the regulating pipe 1, and a fixing flange 22 is provided at the right end of the water outlet pipe 21.

[0024] When the water flow regulating structure of the oilfield development water injection device is in use, firstly, align the right end of the regulating pipe 1 with the left end of the inlet pipe 16, and tightly fit the right wall of the right end mounting flange 14 with the left wall of the connecting flange 17.

During this process, the double-sided toothed plate 8 can drive the guide block 7 to move smoothly through the guide rod 6. Since the rotating gears 10 on both sides mesh with the two sides of the double-sided toothed plate 8, as the double-sided toothed plate 8 moves, the double-sided toothed plate 8 can drive the rotating gears 10 on both sides to rotate in opposite directions.

When the two adjusting arc plates 12 are fully unfolded and tightly fitted to the built-in sealing ring 11, the inner diameter of the adjusting pipe 1 is completely blocked and the water flow is completely cut off. This design not only ensures the accuracy of adjustment, but also greatly enhances the sealing performance of the device. In summary, this utility model, through its precise mechanical linkage design, allows operators to easily and accurately control the water flow rate simply by rotating the adjusting wheel 3, greatly improving the flexibility and efficiency of water injection operations in oilfield development.

[0025] Through the above steps, when the water flow regulation structure of the oilfield development water injection device is in use, firstly, the operator rotates the regulating wheel 3, which in turn drives the regulating gear 5 to rotate via the regulating shaft 4. Since the regulating gear 5 meshes with the double-sided toothed plate 8, it can drive the double-sided toothed plate 8 to move parallel. During this process, the double-sided toothed plate 8 can drive the guide block 7 to move smoothly via the guide rod 6. Because the rotating gears 10 on both sides mesh with the two sides of the double-sided toothed plate 8, as the double-sided toothed plate 8 moves, it can drive the rotating gears 10 on both sides to rotate in opposite directions. The rotating gears 10 on both sides can then drive the regulating arc plates 12 on both sides via the rotating shafts 9 on both sides. Now unfolding in the opposite direction, as the two adjusting arc plates 12 unfold or close, the inner diameter of the adjusting pipe 1 can be adjusted to open or close, thereby allowing for convenient adjustment of the water flow rate. When the two adjusting arc plates 12 are fully unfolded and tightly fitted to the built-in sealing ring 11, the inner diameter of the adjusting pipe 1 is completely blocked, and the water flow is completely cut off. This design not only ensures the accuracy of adjustment but also greatly enhances the sealing performance of the device. In summary, this utility model, through a precise mechanical linkage design, allows operators to easily and accurately control the water flow rate by simply rotating the adjusting wheel 3, greatly improving the flexibility and efficiency of water injection operations in oilfield development.
