摘要
五里湾一区长6油藏是长庆目前年产油量最大的一个区块，其多年的稳产经验值得总结、推广。将理论研究和矿场数理统计方法相结合，系统总结了五里湾一区的见效规律、见水规律、含水变化规律、产量递减规律、采液采油指数变化规律等开发规律，对类似特低渗透油藏的开发具有很好的借鉴意义．并提出利用相渗曲线评价开发效果的新方法。
The Chang6 oil reservoir in Wuliwan No.1 area is the block which has the highest oil capacity at present, and its experience of multi-year stable capacity should be summarized and popularized. This article combines the theoretical research and the mathematical and physical statistic method in the mine field, systematically summarizes the effective rule, water rule, water-content change rule, diminishing rule of capacity, index change rate of liquid and oil collection and other development rules in No.1 area of Wuliwan, which can provide experience for developing the similar oil reservoir （s） of super-low permeability, and provides a new method for evaluating the development effect by relative permeability curve.
