Oil Washing and Increasing Production Technology

1、Brief Introduction of Technical

（1）Surfactant changed the wettability of rock surface and gradually began to absorb water.

（2）Water absorption increases - water drives oil from the rock.

（3）The displaced crude oil flows through the fractures to the wellbore until produced.

2、Technical Features

（1）The surface wettability can be optimized to increase the oil recovery. The self-priming can promote the oil and gas into the oil and gas accumulation area, which is helpful to reduce the formation blockage.

（2）It has good water solubility, stability, good compatibility, good compatibility with produced water and other chemical agents.It can be directly added to other production fluids for easy use. It can quick increased oil and decreased cost (high oil and gas yield returns).

（3）Because of its high economic benefit and low concentration, custom-made products can be provided according to the actual conditions of the oil field, and the performance and environmental acceptability of DSZC can be improved by combining with advanced nanotechnology and biotechnology.

（4）No pollution, friendly to the environment, no damage to the formation.

3、Application Mode

（1）Production Well Single Well Huff and Puff Operation

（2）Work together with other single well measures (acidification, fracturing, scale control, etc.)

（3）Applied to injected water, applied to the whole well pattern to enhance oil recovery

（4）It is compatible with all known production-increasing fluids and production water systems.
