Description

Technical Field

[0001] This utility model is an oil well surface equipment for oil extraction using oil pumping units in oil fields, and is a pumping unit power injection device. Background Technology

[0002] Currently, most wells in oilfields use pumping units for oil production. To ensure the normal production of these wells, wellhead booster equipment is needed for maintenance of the pumping units and wells, such as adding lubricating oil to the pumping units and injecting chemical agents into the wells. Existing wellhead booster equipment requires a power unit, such as an electric motor, which necessitates a power supply. However, some well sites do not allow power connections, making such equipment unusable. Furthermore, the equipment is complex and expensive to manufacture. While some wells currently use solar power to supply electricity to their equipment, this method is only suitable for intermittent operation, as there is no electricity on cloudy days, making it unsuitable for the maintenance needs of pumping units and wells. Summary of the Invention

[0003] The purpose of this invention is to design a pumping unit kinetic energy injection device that can operate without external power supply, utilizing the kinetic energy of the pumping unit during operation to provide an injection device for the maintenance of the pumping unit and oil well.

[0004] The purpose of this utility model is achieved as follows: It includes a driven pulley, a friction wheel, a booster pump, a belt, a driving pulley, a pumping unit base, and a support. A beam pumping unit is installed on the wellhead. The bottom of the beam pumping unit has a pumping unit base. The beam pumping unit has a motor, and the motor has a driving pulley. The beam pumping unit has a gearbox, and the gearbox has a driven pulley. The driving pulley and the driven pulley are connected by a belt. The lower part of the support is installed on the pumping unit base, and the friction wheel is installed on the upper part of the support. The friction wheel is located below and abuts against the belt, so that the belt can drive the friction wheel to rotate when it moves. The input end of the booster pump is connected to the friction wheel, so that the rotation of the friction wheel can drive the booster pump to work.

[0005] As an optimized solution, the friction wheel and the booster pump are connected by a coupling.

[0006] As an optimized solution, a speed reducer is installed between the friction wheel and the booster pump.

[0007] As an optimized solution, a storage box is installed on the wellhead, and a booster pump is installed on the storage box, with the suction end of the booster pump inserted into the storage box.

[0008] The beneficial effects of this invention are as follows: When the pumping unit is running, it drives the booster pump to pressurize the lubricating oil or chemical agents in the storage tank and deliver them to the operating parts of the pumping unit or the oil well through the pipeline network. Therefore, this invention utilizes the motor power of the pumping unit to automatically inject lubricating oil into the rotating parts of the pumping unit; it can also inject chemical agents into the well, thus enabling production maintenance of the oil well. This invention can operate without external power supply, meeting the requirement that no additional electrical equipment can be connected at the well site, providing a safe and reliable booster device for pumping unit and oil well maintenance, and has significant economic benefits.

[0011] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0012] like Figure 1 As shown, the embodiment of this utility model includes a driven pulley 1, a friction wheel 2, a booster pump 4, a belt 6, a driving pulley 7, a pumping unit base 8, and a bracket 9. A beam pumping unit is installed on the wellhead. The bottom of the beam pumping unit is equipped with the pumping unit base 8. The beam pumping unit has a motor, and the motor has a driving pulley 7. The beam pumping unit has a gearbox, and the gearbox has a driven pulley 1. The driving pulley 7 and the driven pulley 1 are connected by the belt 6. The lower part of the bracket 9 is mounted on the pumping unit base 8. The friction wheel 2 is mounted on the upper part of the bracket 9, positioned below and abutting against the belt 6, so that the belt 6 can drive the friction wheel 2 to rotate when it moves. The input end of the booster pump 4 is connected to the friction wheel 2, so that the rotation of the friction wheel 2 can drive the booster pump 4 to work. The booster pump 4 is generally a plunger pump, gear pump, or other pump type.

[0013] Friction wheel 2 and booster pump 4 are connected by coupling 3. Coupling 3 is a universal joint coupling.

[0014] A speed reducer 10 is installed between the friction wheel 2 and the booster pump 4.

[0015] A storage box 5 is installed on the wellhead, and a booster pump 4 is installed on the storage box 5, with the suction end of the booster pump 4 inserted into the storage box 5. If the reducer 10 requires support, the reducer 10 is also installed on the storage box 5.

[0016] When the beam pumping unit is running, it drives the booster pump 4 to work. The output end of the booster pump 4 is equipped with an oil injection pipe and an oil outlet (oil nozzle on the grease gun). After the pipe is connected to the rotating part of the oil pump, the lubricating oil in the storage tank can automatically inject lubricating oil into the rotating part of the pumping unit. Chemical agents are placed in the storage tank and connected to the well casing, so that chemical agents can be injected into the well, thereby enabling production maintenance of the oil well.

[0017] The height of bracket 9 is adjustable to accommodate different models of beam pumping units and to adjust the contact force between the friction wheel and the belt.

[0018] The attached drawings do not show the complete structure of the beam pumping unit. Beam pumping units are commonly used pumping units, and those skilled in the art can know the positions of the motor pulley and gearbox pulley. Therefore, it is not necessary to show the complete structure of the beam pumping unit to understand the content of this utility model.

[0019] If cleaning agent is placed in storage box 5, the wellhead and pumping unit of the oil well can be cleaned.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
