摘　　要：530井区J1b4+5层油藏属断层遮挡-岩性复合圈闭砾岩油藏,已进入高含水递减阶段,地质模型与剩余油分布认识不够,常规动态管理存在不定量、结果不可预测性等问题,近年通过开展高含水期精细油藏描述及数模动态预测研究,精细地质建模,定量描述剩余油,突破了原有认识。2002-2006年应用油藏描述成果及数模预测技术,实施油藏由定性向精细油藏定量化管理转变,2002-2006年平均绝对年油量油量递减仅为1.6%,采收率提高4个百分点,增加水驱可采储量55.5×104t,实现了油藏持续稳产。530 well block J1b4+5Layer reservior has come into the stage of high water-bearing degression which causes a lot of problems in dynamic management.From 2002 to 206,Reservior description and digital model prediction technologies have been applied so that reservior management truns from qualitative one to quantitative on.Oil recovery rate increases by 4% and persistene oil production is realized.
