摘　　要：以渤海A油田为例,通过分析无因次采油、采液指数变化规律和已提液油井生产状况,研究了提液的可行性;利用数值模拟手段,采用均匀设计法设计试验方案,开展海上油田早期注聚提液开发技术政策界限研究,确定了合理的提液时机和提液幅度。研究结果表明,对于A油田来说,在聚合物驱整体见效时提液效果最佳,合理的提液幅度为提液前产液量的1.3倍左右,在聚驱的基础上再提液可提高采收率约0.8%。Taking A oilfield in Bohai sea as an example,the feasibility of lifting liquid was researched by analyzing the dimensionless oil production,the changes of fluid productivity index and the production performance in wells with lifted liquids.By using a numerical simulation tool,a uniform design method was adoped to establish a pilot project,by which the technical policy limitation of lifting liquid during early polymer flooding in offshore fields was researched,resulting in the determination of rational time and extent of lifting liquid.For A oilfield,the results have indicated that the best effects of lifting liquid will occur when polymer flooding is overall effective,that the rational extent of lifting liquid is 1.3 times the liquid production before lifting liquid,and that the lifting liquid after polymer flooding may increase oil recovery by 0.8%.
