1、 Application field
polyacrylamide is used as an oil displacement agent in the petroleum exploitation industry to increase the viscosity of injected water, improve the oil-water mobility ratio, expand the swept volume and improve the crude oil recovery. Polyacrylamide can be used alone or in combination with alkali and surfactant to form binary or ternary composite flooding. Polymer flooding, binary and ternary composite flooding are the main measures to further control oil production cost and enhance oil recovery in the later stage of oilfield water flooding. 2、 Product characteristics this product is a tertiary oil recovery product developed through special molecular design according to oil displacement mechanism and reservoir characteristics. The product has remarkable viscosity increasing effect, good high temperature and high salt resistance, shear resistance and good thermal stability. It can effectively increase the viscosity of displacement fluid, improve sweep coefficient, increase sweep volume and improve crude oil recovery. 3、 Product index 1.
