摘要
针对陆相砂岩油田特高含水期开发阶段剩余油分布零散复杂的状况 ,从沉积学理论入手 ,对萨、葡储层进行精细解剖 ,揭示了储层沉积模式及非均质特点 ,从成因上分析特高含水期萨、葡储层剩余油分布特点。喇嘛甸油田萨、葡储层的剩余油一般富集在点坝砂体顶部、边部 ,主要条件是注采方向与渗流方向不一致 ,而其他类型砂体形成富集剩余油的主要原因是砂体物性变差、注采不完善、滞留区未射孔及井网控制不住等类型 ,措施调整方案实施后 ,取得了良好的挖潜效果。
Because of the scattered and complicated distribution of residual oil in land facies sandstone oilfield during its development of ultra-high water cut period, the paper following sedimentology finely anatomizes Saertu-Putaohua reservoirs, announces its sedimentary pattern and heterogeneous characteristic in the cause of formation, gains good effect on bring the adjustment scheme into effect, and provides advantageous geological evidence for residual oil potential seeking of various reservoirs.
