Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil well technology, and in particular to a power self-circulation control system for oil wells. Background Technology
[0002] Oil well production refers to the process of extracting underground oil to the surface through wells located in oil reservoirs using various methods. Oil well production equipment includes an oil production system, a power system, and a gas-liquid separation system. The oil production process requires electricity as a power source. The extracted crude oil needs to be heated to reduce its viscosity and to separate oil, water, and gas before being collected and transported.
[0003] The entire production process of oil well extraction requires electricity, which is a significant energy consumption. Moreover, these processes are often carried out in remote areas with limited resources, making power supply difficult and costly. Therefore, those skilled in the art have developed a power self-circulation control system for oil wells to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a power self-circulation control system for oil wells. This system achieves power self-circulation in oil wells through continuous circulation, thus solving the problems of power supply and crude oil heating in oil wells.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a power self-circulation control system for an oil well, comprising a generator, a gas-liquid separator, a burner, a multi-functional tank, an oil production machine, and a motor body, wherein the generator is connected to the motor body, the gas-liquid separator is connected to the generator, and the gas-liquid separator is connected to the multi-functional tank;
[0006] The burner is connected to the upper end of the gas-liquid separator. The burner is installed inside the multi-functional tank. The multi-functional tank is connected to the oil extraction machine. The oil extraction machine is connected to the main body of the motor.
[0007] This utility model has the following beneficial effects:
[0008] The self-circulating power control system for oil wells proposed in this utility model uses gas separated from crude oil to generate electricity through combustion. The generated electricity can be used as power for the oil extraction system and processing. The heat from combustion can be used to heat the crude oil in a multi-functional tank to reduce its viscosity. The heated crude oil is then transported to a gas-liquid separator for the separation of oil, water, and gas. The separator has a liquid level control valve. When the crude oil reaches a certain liquid level, the control valve opens, and the separated crude oil is pumped to a storage tank for storage. The separated water is discharged and treated, and the separated gas is used for combustion to generate electricity and heat the crude oil. This cycle repeats continuously to achieve self-circulating power for the oil well, solving the problems of power supply and crude oil heating in oil wells. Attached Figure Description
