Physical simulation experiments on profile control and flooding of crosslinked polymer in edge-water reservoir

According to the characteristics of edge water within Gaoqianbei block in Shengli oilfield,the procedure and the program of physical simulation experiments is designed for the study on the profile control and flooding of crosslinked polymer in edge-water reservoir by available equipments. The experimental results show that the crosslinked polymers injected into the core are characterized by rapid cementation, high intension,high anti-washing capacity,thus enhancing the recovery rate of edge-water reservoir.The experiments prove that the crosslinked polymer profile control and flooding in edge-water reservoir is feasible,and provide reliable proofs for the profile control and flooding exploration and to enhance oil recovery of the edge-water reservoir in Gaoqianbei block.
