摘　　要：根据胜利油田高浅北区边水存在的特点,利用现有实验装置,研究设计了边水油藏交联聚合物物模实验流程,同时设计了实验方案。物理模拟实验结果表明,注入的交联聚合物体系具有成胶良好、强度大。稳定性好、耐冲刷能力强的特点,对边水油藏提高采收率幅度较高,边水油藏进行交联聚合物调剖是可行的。该实验为具有边水的高浅北区进行交联聚合物调驱开发、提高采收率提供了可靠的实验依据。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.
