摘要： 针对注聚中后期含水率急速上升、 各油层动用程度差异大的现象, 提出了一种改善油层动用程度的 新方法, 分阶段合理调整压力系统确定阶段产液水平, 并已在矿场试验中取得了较好的效果。以大庆喇嘛甸油田为 例, 应用数值模拟技术研究了调整流压后产液量、 压力、 含水率等多项开发指标的变化规律, 对比开发效果表明, 聚 合物驱保持6MP a ( 较高) - 2MP a ( 较低) - 6MP a ( 较高) 流压时, 注聚1. 0P V后含水率降低1. 4 6%, 聚驱采出程度提高 约2. 4 3%, 各层开发动用程度最好。

Abstract: For the phenomenon that the rapid rise of water cut and a big difference in using degree between various layer types in the late stage of polymer injection, a new method that has achieved good results in field test is proposed. The flow pressure can be reasonably adjusted by stage andproduction levels can also be determined. For example, Lamadian Daqing Oilfield, variation of development indicators(such as production, pressure profile, etc) is studied after adjusting flow pressure through numerical simulation techniques. Compared to development effect, it is showed that when flow pressure is kept 6 MPa(higher)2 MPa(lower)6 MPa(higher), water cut is reduced by 1.46 percentage points, and degree of polymer flooding cumulative recovery is reduced by about 2.43 percentage points after 1.0 PV is injected, of which producing degree is best
