摘 要:为了解决胜坨油田一区沙二段1-3单元注聚扩大区提液效果差的问题,利用数值模拟手段研究了聚合物驱合理提液时机和提液幅度,同时结合扩大区的地质及开发状况分析。制定了合理提液原则。研究结果表明,聚合物驱提液的最佳时机为整体见效后;最佳提液幅度为10%-20%;提液应以非主流线方向的油井以及剩余储量丰度高的井区为主。应用以上原则采取提液措施后,提液井产液量由530t/d增至I656t/d。产油量由53t/d增至169t/d。含水率下降了0.2%。In order to solve the issue of few increasing liquid production in expending test area of polymer injection, 1-3 units in Es2 of No. 1 area in Shengtuo Oilfield, rational increasing liquid production time and range of the area are studied using numerical simulation. Rational increasing liquid production principle is set up based on the geologic and development situation analysis of the area at the same time. The optimized time is after whole response, and the best increasing liquid production range is 10% to 20%. The oil wells in non - main stream line direction and the well blocks with high residual reserve abundance should be the main objects in liquid production increasing. After application, the liquid production increased from 530t/d to 1 656t/d and the oil production increased from 53t/d to 169t/ d,and water cut decreased 0.2% in the wells with liquid production increasing.
