摘　　要：针对57复杂断块油田目前暴露的产量递减快等一系列问题,从水驱采收率、油层动用程度、水驱动用程度和阶段存水率四个方面对该油田进行了油藏工程评价;建立模拟区的地质模型并利用数值模拟技术对该油田的剩余油分布规律进行了研究,并在此基础上提出了挖潜措施;对其挖潜措施进行效果预测,结果表明在评价期15年内累积增油量达11多万吨,降水效果显著,该挖潜措施可行。Oil production depletes seriously in Zhao 57 fault block at present,in view of this difficult problem,this paper study reservoir engineering evaluation in four aspects of water drive recovery ratio,producing degree of oil layers,producing degree of water drive and stage water storage percentage.In this thesis, a geology model is established,and numerical simulation is carried on residual oil distribution of Zhao 57 fault block.Based on this result,a top potential measure is proposed,and its effect is predicted.The results indicate that incremental oil is more than 11×104 ton and effect is significant,so a top potential measure is feasible.
