Working Principle of Oil Field Injection Pump


After the oil field is put into development, with the increase of mining time, the energy of the reservoir itself will be consumed continuously, resulting in the continuous decrease of reservoir pressure, the large degassing of underground crude oil, the increase of viscosity, the greatly reduced production of oil wells, and even the stoppage. In order to make up for the underground deficit caused by crude oil extraction, to maintain or increase the reservoir pressure, to realize high and stable oil yield and to obtain higher recovery rate, it is necessary to inject water into the oil field.


The measures to replenish and maintain the reservoir pressure are called water injection by injecting water into the reservoir through the water injection well.


The selection of water injection pump type should be considered according to the specific conditions of oil field, reservoir structure, area size and comprehensive benefit of technology and economy. The treated water is pressurized by the water injection pump, then divided into each injection well through the water distribution room, and the flow rate of the injected water is measured in the water distribution room.

Working Mode of High Pressure Injection Pump in Oil Field


The water injection mode is the injection and production system, which refers to the position of the injection well in the reservoir and the arrangement relationship between the injection well and the production well. The following can be selected according to the characteristics of the oil field


Water injection mode:

Edge water injection is divided into three types: outer edge water injection, upper edge water injection and inner edge water injection.

Cut water.

  Area water injection can be divided into five points, seven points, crooked seven points, four points and nine points.
