摘要
为实现高尚堡油田高浅北区的持续稳产和提高采收率,把交联聚合物调驱技术应用到高浅北区。2008年根据高浅北区油藏条件及剩余油情况分析了高浅北区交联聚合物整体调驱可行性,并根据多方面因素确定了交联聚合物整体调驱的目标区,共设计了26口调驱井;设计了交联聚合物调驱体系配方和科学合理的注入方案。交联聚合物调驱技术在高浅北区的应用已经取得了显著效果,注入压力上升,日采油量上升,提高了原油采收率,表明该技术适用于边水油藏。
To stabilize oil production and enhance oil recovery continuously in Gaoqianbei block, the profile control and displacement technology of cross-link polymer is put into use. According to the reservoir characteristics and residual oil in Gaoqianbei block, the feasibility of the bulk profile control and displacement using cross-link polymer in Gaoqianbei block is analysed. At the same time, the target area is selected and 26 wells are designed for profile control and displacement. The system of profile control and displacement is also optimized. Furthermore., numerical simulation is used and economical factor is considered, and the scientific and reasonable plan is designed. The results indicate that the technology is suitable for edge-water reservoir and oil production is enhanced.
