An Experimental Study on Adaptability of a Novel Living Polymer Used in Low Permeability Fractured Reservoir

Article Preview

Abstract:

In this paper, the produced water in Daqing oilfield was detected, includes the viscosity and concentration ratio of living polymer (LH-1), interfacial tension and swelling rate of particle polymer (LHP-1). And its adaptability in low permeable fracture core was also tested. The results show that the injection property is good if the living polymer (LH-1) and the particle polymer (LHP-1) are used together, the volume-expansion particle polymer can effectively plugging the high permeable layer in bottom of the reservoir and improve water injection profile. The best injection volume of LH-1is 0.32 PV, and enhances oil recovery rate is 18.4%.
