Oilfield water injection is a measure to inject water into the oil layer through the injection well, maintain the pressure of the oil layer, and improve the oil recovery rate and recovery factor. The water produced by oilfield drilling can be re-injected after filtration to ensure that the raw water does not block pipelines and water injection equipment, so filtration is required.

SP Solution:

The filter adopts multi-stage filtration, and the filtered water can be used for re-injection and discharge.

The first-stage filtration adopts an automatic backwash filter to reduce the 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 particles in the liquid.

The three-stage filtration uses a biochemical device to separate the dissolved oil in the liquid.

The four-stage filtration adopts an ultrafiltration device, which can recycle the liquid.

SP Advantages:

ØThe control system is responsive and runs accurately.

ØCleaning is efficient and thorough, and the filter screen can be completely restored to its original state.

ØContinuous operation, stable and reliable.
