摘　　要：针对复杂断块油藏注水开发后期平面矛盾加剧、剩余油分布特征复杂的问题,提出了一种断块油藏多目标生产优化方法。通过将多目标优化算法应用到断块油藏注采优化过程中,对油藏不同部位设置各自的优化目标,从而实现不同部位各自独特的优化策略并同时达到最优化的效果。将该方法应用于断块油藏模型中进行测试,对不同区域占优结果进行方案选取,对比生产数据变化情况以及剩余油分布特征,发现该方法能够使油藏不同部位均能达到各自的预期目标,有效地改善了油藏的平面矛盾。该研究成果对断块油藏的开发具有一定的借鉴意义。A multi-objective production optimization method was proposed to improve the series lateral contradiction and the complex residual oil distribution in the late waterflooding stage of complex fault-block oil reservoir.The specific optimization objectives of different reservoir parts were set by applying this multi-objective optimization algorithm to the fault-block oil reservoir injection-production optimization.The specific optimization strategies for different oil reservoir parts were gained to synchronously obtain optimization.This method was applied to a fault-block reservoir model for test.The dominant programs for different reservoir parts were taken to compare the differences in production performance and remaining oil distribution.It is found that this method could achieve expected optimization for the different oil reservoir parts,which effectively improves the lateral reservoir contradiction.This research could provide certain reference for the development of fault-block oil reservoir.
