摘 要：
对海上油田岩心聚合物驱试验的油藏数值模拟反演与应用进行了探索,针对水驱、聚合物驱阶段特点,分析了不同因素对于含水率指标的影响,确定了反演工作的步骤和策略。一方面核实了岩心试验数据,校正了油藏条件下的聚合物驱工作参数;另一方面利用反演模型对类似试验进行模拟预测,分析聚合物驱规律,减少了重复试验工作量和成本,提高了聚合物驱研究工作的质量和效率。反演模型中采用在注入端加密网格、添加注入井的方法,改善了注入压力的拟合效果。通过岩心聚合物驱试验与数值模拟反演工作表明早期注聚可以在海上油田有限的开发周期内提高采收率和开发效率。

摘 要：
Reservoir simulation inversion in core polymer flooding experiments of offshore oilfield and its application were studied.According to the characteristics of waterflooding and polymer flooding,the effect of different factors on watercut indication was analyzed,the simulation steps and strategies were determined.On the one hand core experimental data and polymer flooding parameters were verified;and on the other hand the inversion simulation model was used to predict other similar experiments and analyze the law of polymer flooding to reduce the working load and the cost of repeated tests,by which the operation quality and efficiency of polymer flooding were enhanced.Local grid refinement and multiinjector method were used in the simulation model,which improved the injection pressure simulation obviously.Both the core experiments and inversion simulation results show that early polymer flooding can improve the offshore oilfield development efficiency and recovery in the limited platform life.
