姬塬油田姬37井区采收率评价

Recovery factor evaluation of Ji 37 area inJiyuan oilfield

针对以往采收率评价中存在的问题,结合姬塬油田姬37井区低孔低渗油藏开发实际,采用水驱曲线特征法、产量递减法、改进的童式曲线法以及经验公式法对该区块的采收率进行定量评价,为进一步提高开发效果,挖掘剩余油,编制及调整开发方案提供理论指导。

According to The past the problems existing in the recovery evaluation,Combining with the development practice of the low permeability and low porosity reservoirs of Ji 37 Area in Jiyuan oilfield,many kinds of methods,such as the actual curve,production decline method and Tongshi plate contrast method,water-drive curve method as well as empirical formula method,were used to carry out quantitative evaluation of the recovery efficiency of this oil group,and to discover the main problems and the contradiction.Then the theoretical guidance will be provided for further enhancing the effect development,digging into the remaining oil,and the preparation of development programs.
