High pressure pump control system

With the continuous development of my country's petroleum industry, the exploitation of oil fields has continued to increase. Technical bottlenecks in the development of oil fields have gradually become apparent. In the past, after many oil fields were put into production, with the extension of production time and changes in related influencing factors, oil wells stopped blowing out in the later stages of oil field production and residual dead oil could not be recovered, which led to an increase in the difficulty and cost of oil field production.

In order to achieve high production and stability of oil fields, oilfield water injection technology emerged as the times require. By injecting water into oil wells, it can make up for the underground deficit caused by the extraction of crude oil, maintain or moderately increase the oil layer pressure, and promote the sustainable exploitation of oil wells. Piston pumps are widely used in the field of oil field water injection.

Piston pump is a type of water pump, which is widely used in energy, electric power and construction. Because the plunger pump can output liquid under high pressure, it has become the best choice for the power system of petroleum water injection technology. The plunger pump complete control system collects various wellhead sensor parameters, including wellhead inlet and outlet pressures, lubricating oil temperature, inlet liquid level and inlet flow rate, etc., to control the motor speed and valve opening, thereby realizing the injection of the plunger pump. The constant pressure at the nozzle and the smooth and safe operation of the equipment are currently being developed from simple manual operations to informatization, digitalization and intelligence by integrating with the mobile Internet, cloud computing, Internet of Things and modern manufacturing.
