Oilfield reinjection water filtration system

      The oilfield reinjection water filtration system is a measure to inject water into the oil layer through the injection well, maintain the oil layer pressure, and increase the oil recovery rate and recovery rate.

  Description of working conditions:

  The oilfield reinjection water filtration system is a measure to inject water into the oil layer through the injection well, maintain the oil layer pressure, and increase the oil recovery rate and recovery rate.

  Device Description:

  Zhengyuan has successfully reduced the suspended solids, oil and particles in the reinjected water to the 1:1:1 standard in Daqing Oilfield, which is the highest standard not achieved by ultrafiltration in China. The biggest advantage of this solution is the high-efficiency automatic filtration system.

  Filtration process description:

  The filter uses multi-stage filtration and the filtered water can be used for reinjection and discharge.

  The primary filtration uses an automatic backwash filter to reduce suspended solids and solid particles in the liquid to within 1 micron.

  The secondary filtration uses an air flotation device to separate the large oil in the liquid.

  The tertiary filtration uses a biochemical device to separate the dissolved oil in the liquid.

  The four-stage filtration uses an ultrafiltration unit to recycle the liquid.
