Description

Technical Field

[0001] This utility model relates to the field of oilfield development technology, specifically to a multi-well control energy-saving device. Background Technology

[0002] In the oilfield development sector, multi-well gathering and transportation is a core model for improving production efficiency. It uses a unified pump and pipeline system to centrally transport crude oil produced from multiple wells to a processing station. However, due to differences in geological conditions and development stages, the oil production and pipeline pressure of different wells can fluctuate significantly.

[0003] Existing multi-well control systems typically use a single pump to drive multiple well pipelines. The pump power needs to be set according to the demand of the highest-producing well. However, the actual oil production of most wells is lower than the design value. In this case, the pump is in a "powered but underpowered" state, with a high power redundancy rate and higher daily power consumption than ideal. This leads to increased oilfield extraction costs and can easily cause pipeline overload and reduced transportation efficiency, thus restricting the economic efficiency and stability of oilfield extraction. Utility Model Content

[0004] In view of the problems existing in the above-mentioned well control energy-saving devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a multi-well control energy-saving device, which solves the problem that multi-well control devices lack a targeted flow and pressure adaptive adjustment mechanism, resulting in a mismatch between pump operating power and actual demand, serious energy waste, and problems such as pipeline overload and reduced transportation efficiency, thus restricting the economic efficiency and stability of oilfield development.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-well control energy-saving device includes multiple first fixing blocks, each of which has an internal cavity. Circular holes are formed on the upper and lower surfaces of two cavities. A four-way pipe is fixedly connected to the internal cavity of the upper circular hole of each cavity, with a pump body fixedly connected to one end of the four-way pipe. An oil well pipe is fixedly connected to the internal cavity of the lower circular hole of each cavity. A baffle is slidably disposed inside each cavity. An adjustment mechanism is provided inside each cavity, and each baffle moves through a corresponding adjustment mechanism. A second fixing block is fixedly connected to one side of each first fixing block. A sliding groove is formed inside each second fixing block, and a driving mechanism is provided inside each sliding groove. The adjustment mechanism matches the driving mechanism.

[0007] Preferably, the adjusting mechanism includes multiple lead screws and multiple gears. Each lead screw is rotatably connected to the interior of a corresponding cavity. One end of each baffle is provided with an internal thread groove. Each baffle is threaded onto the wall of the corresponding lead screw through a corresponding internal thread hole. One end of each lead screw passes through one side of the corresponding cavity and extends into the interior of the corresponding slide groove. Each gear is fixedly sleeved onto the wall of one end of the corresponding lead screw.

[0008] Preferably, the driving mechanism includes multiple L-shaped blocks, multiple pistons, multiple connecting rods, and multiple racks. Two L-shaped blocks are respectively fixedly connected to one side of the corresponding oil well pipeline. Each L-shaped block has an L-shaped groove inside. Each piston is respectively sealed and slidably disposed inside the corresponding L-shaped groove. Each connecting rod is respectively fixedly connected to the upper surface of the corresponding piston. The upper end of each connecting rod passes through the upper surface of the corresponding L-shaped groove. Each rack is respectively slidably disposed inside the corresponding groove and is respectively fixedly connected to the upper end of the corresponding connecting rod. Each rack meshes with a corresponding gear.

[0009] Preferably, each cavity has a first limiting groove symmetrically formed inside, and each first limiting groove has a limiting block slidably arranged inside, with each limiting block being fixedly connected to the upper and lower surfaces of the corresponding baffle.

[0010] Preferably, a second limiting groove is provided on one side of each of the slide grooves, and a limiting strip is slidably provided inside each of the second limiting grooves. Each limiting strip is fixedly connected to one side of the corresponding rack.

[0011] Preferably, each of the oil well pipes has an oil outlet hole on one side, and each oil outlet hole is matched with a corresponding L-shaped groove.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model automatically adjusts the opening of a baffle based on the actual pressure of a single oil well to achieve dynamic flow distribution. When the pressure of a certain oil well increases, the baffle automatically opens wider to increase the cross-section through which crude oil passes; when the pressure decreases, the baffle automatically closes smaller, avoiding the waste of power by using a large horse to pull a small cart, thereby achieving energy saving. 2. This utility model enables individual control of the flow rate of multiple wells by using an independent adjustment mechanism and drive mechanism for each oil well pipeline, without interference between them, thus preventing the situation where damage to the control device of a single oil well pipeline affects other oil well pipelines.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a multi-well control energy-saving device.

[0020] This utility model provides, for example Figure 1-3 The multi-well control energy-saving device shown includes multiple first fixing blocks 1. Each first fixing block 1 has a cavity inside. The upper and lower surfaces of the two cavities have circular holes. A four-way pipe 2 is fixedly connected to the interior of the circular hole above each cavity. A pump body 3 is fixedly connected to one end of the four-way pipe 2. An oil well pipe 4 is fixedly connected to the interior of the circular hole below each cavity. A baffle 5 is slidably installed inside each cavity. An adjustment mechanism is installed inside each cavity. Each baffle 5 moves through a corresponding adjustment mechanism. A second fixing block 6 is fixedly connected to one side of each first fixing block 1. A groove is opened inside each second fixing block 6. A drive mechanism is installed inside each groove. The adjustment mechanism matches the drive mechanism.

[0021] Existing multi-well pipelines typically have the same diameter, so each well pipeline 4 receives the same amount of power. This device adjusts the pressure inside the well pipeline by regulating the cross-section through which oil passes in each well pipeline 4, allowing the well pipeline with higher internal pressure to receive more power, thereby improving the efficiency of oil well extraction and achieving energy conservation.

[0022] like Figure 1-3 As shown, the adjusting mechanism includes multiple lead screws 7 and multiple gears 8. Each lead screw 7 is rotatably connected to the interior of a corresponding cavity. One end of each baffle 5 has an internal threaded groove. Each baffle 5 is threaded onto the wall of the corresponding lead screw 7 through a corresponding internal threaded hole. One end of each lead screw 7 passes through one side of the corresponding cavity and extends into the interior of the corresponding slide groove. Each gear 8 is fixedly sleeved onto the wall of one end of the corresponding lead screw 7. The driving mechanism includes multiple L-shaped blocks 9, multiple pistons 10, multiple connecting rods 11, and multiple racks 12. Two L-shaped blocks 9 are fixedly connected to the corresponding... On one side of the oil well pipe 4, each L-shaped block 9 has an L-shaped groove inside. Each piston 10 is sealed and slidably disposed inside the corresponding L-shaped groove. Each connecting rod 11 is fixedly connected to the upper surface of the corresponding piston 10. The upper end of each connecting rod 11 passes through the upper surface of the corresponding L-shaped groove. Each rack 12 is slidably disposed inside the corresponding groove and fixedly connected to the upper end of the corresponding connecting rod 11. Each rack 12 meshes with the corresponding gear 8. Each side of the oil well pipe 4 has an oil outlet hole, and each oil outlet hole matches the corresponding L-shaped groove.

[0023] The crude oil pressure in each well pipeline 4 is transmitted to the L-shaped groove of the L-shaped block 9 through the oil outlet on one side of the pipeline. When the oil production of the well changes, causing the pipeline pressure to fluctuate, the pressure in the L-shaped groove changes accordingly, pushing the piston 10 to slide in the L-shaped groove. When the oil well pipeline pressure increases, the crude oil pushes the piston 10 to move upward along the L-shaped groove, and drives the rack 12 to rise synchronously in the sliding groove of the second fixed block 6 through the connecting rod 11. When the oil well pipeline pressure decreases, the pressure in the L-shaped groove decreases, and the piston moves downward under the action of gravity or crude oil backflow pressure, driving the rack to fall synchronously. When the rack 12 moves, its tooth surface meshes with the gear 8 on the lead screw 7, driving the lead screw to rotate in the cavity of the first fixed block 1. The lead screw 7 cooperates with the internal thread groove of the baffle 5. When the lead screw rotates, it drives the baffle to slide along the cavity, thereby regulating the flow rate inside the oil well pipeline and avoiding the situation where the flow rate of a single oil well is too small and occupies too much power of the pump body.

[0024] like Figure 1-2 As shown, each cavity has a first limiting groove symmetrically provided inside, and each first limiting groove has a limiting block 13 slidably provided inside, and each limiting block 13 is fixedly connected to the upper and lower surfaces of the corresponding baffle 5.

[0025] Each limit block 12 can be used to make each baffle 5 move stably.

[0026] In order for the rack to mesh stably with the corresponding gear, such as Figure 2As shown, a second limiting groove is provided on one side of each slide groove, and a limiting strip 14 is slidably provided inside each second limiting groove. Each limiting strip 14 is fixedly connected to one side of the corresponding rack 12.

[0027] The limiting strip 14 ensures that each rack 12 can only move up and down, preventing it from separating from the corresponding gear.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
