Product Introduction
Infiltration and absorption extraction agents have good stability and interfacial activity, which can change the wettability of rock surfaces, reduce displacement resistance, and effectively improve the water injection development effect of low-permeability reservoirs by reducing oil-water interfacial tension, increasing infiltration and absorption contact area, and increasing rock surface charge density. The residual oil in the reservoir matrix can be utilized to achieve the goal of improving crude oil recovery.
