Polyacrylamide Oil Field Chemical Oil Displacing Agent For Tertiary Oil Recovery

Polymer Oil-displacing Agent Polyacrylamide For Oil Field Chemicals

Polymer flooding is achieved by adding a certain amount of high molecular weight polyacrylamide to the injected water to increase the viscosity of the injected water, improve the oil-water current ratio,adjυst the water injection profile, expand the swept volume. Since the viscoelasticity of the polymer molecule has a stretching and carrying effect. on the oil film oil droplets, the oil displacement efficiency is improved and the oil recovery efficiency is improved.

Oil displacing agent of oil field tertiary oil recovery:It can adjust the rheology of filled water, increase the

viscosity of driving liquid, improve water drive wave and efficiency, lower water phase permeability in ground

layer, and enable water and oil to flow forward at even speed. Its effect is that it is mainly used in tertiary oil

recovery of oil fields in the aspect oil production, and raw oil of about 100 to 150ton more can be produced

through filling the macromolecule polyacrylamide product one ton.

Well drilling mud raw materials:in oil field exploration and development and exploration of geology, water and

coal, it is used as adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve

the drill speed and drilling footage, and reduce plug in replacing drill, and has prominent well slough

preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
