Reservoir adaptability analysis of different oil displacement agents in polymer flooding

Shuling Gao

Abstract

s:Some oilfields in China have entered the stage of subsequent water flooding after polymer flooding,and it is in urgent need to develop EOR technology after polymer flooding. Therefore physical simulation has been performed to study the percolation capacity of different oil displacement agents and the oil displacement efficiency of polymer flooding. The experiment results show that foam complex system has the highest resistance coefficient and residual resistance factor,the strongest control on fluid mobility,expands swept volume,and further improves oil displacement efficiency by adding surfactant. The recovery factor is improved by 10.6% after polymer flooding.
