介绍了杏树岗油田杏四—六面积西块油藏模拟研究。为了达到研究的目的，建立了规模较大（总节点３８４００个）、能反映多油层油藏分层开采动态的油藏模型。研究中进行了动态数据评价，拟定了合理的历史拟合策略。并对注水量的修正和储量潜力进行了敏感性分析。最后对该区块的表外储层储量潜力，调整加密后的稳产趋势和压力恢复速度进行了研究 This paper introduces the simulation study of Xing 4 - 6 area west reservoir in Xingshugang Oilfield. In order to achieve the purpose of the study, a large reservoir model (38400 nodes in total) was established to reflect the stratified mining dynamics of multi-reservoir. In the study, the dynamic data was evaluated and a reasonable historical matching strategy was drawn up. The water quality correction and reserve potential sensitivity were analyzed. Finally, the potential reserves of off-surface reservoirs in this block, the steady-state trend after adjustment of encryption and the pressure recovery rate are studied
