摘要
江陵凹陷储层类型多,油砂体面积小,平面变化快,且厚度小,地层水矿化度高,黏土矿物差异大,存在一定的储层敏感性,属于中低渗复杂断块油藏。在分析其油藏开发特点的基础上,通过对江陵凹陷低渗油藏历年压裂、酸化、调剖的效果分析,总结了适应于不同物性、不同阶段的措施工艺,为相似油藏降低无效措施、提高开发效果提供了一定的借鉴。
The reservoir in Jiangling Sag belongs to low permeability and complex fault block reservoir,through the research,it attempts to evaluate the effectiveness of fracturing,acidizing,profile control in low permeability reservoir over years,it summarizes the measures of technology used at different stages,it can reduce the effective measures,improve the reservoir development effect and provides certain reference.
