摘要(Abstract)：

受断层遮挡和断砂配置关系影响,断块区岩性油藏剩余油分布十分复杂.分析葡北油田葡萄花油层正向构造识别、沉积微相解剖、断层侧向封闭性和‘断—砂’匹配样式,认为断块区岩性油藏剩余油主要受"势—断—相"及其匹配关系控制,即断块边部正向断圈和内部微幅度构造高点控制剩余油富集部位;断层侧向封闭性影响剩余油富集程度;浅水三角洲水下分流河道及主体席状砂构成剩余油富集优质储层;断层与砂体匹配样式决定剩余油富集层位.建立4种剩余油类型,提出断块边部遮挡型剩余油钻大斜井,微幅度构造型剩余油钻高效加密直井,河道注采不完善型剩余油钻水平井,席状砂非均质性型剩余油采用油井压裂等挖潜方法.该研究结果对高含水期断块油田高效开发具有指导意义.
