安塞油田坪桥加密区开发效果模糊综合评价

Fuzzy Comprehensive Evaluation of Development Effect in Pingqiao Infilling Area of Ansai Oilfield

摘要: 针对低渗透油藏水驱开发特征，选取产量递减率、剩余可采储量采油速度、含水上升率、存水率、耗水率、水驱体积波及系数等开发参数，运用模糊综合评价方法，对安塞油田坪桥区5种加密井网开发效果进行评价。评价结果表明该方法简单方便、可信度较高，可推广应用到其它低渗透油藏加密区。

Abstract: According to the characteristics of water-driven development in low-permeability reservoir, the development parameters such as production decline rate, recovery rate of remaining recoverable reserves, water cut rise rate, water storage rate, water consumption rate, water drive volume sweep coefficient, etc. are selected to evaluate the development effect of five kinds of infill well patterns in Pingqiao area of Ansai Oilfield by using the fuzzy comprehensive evaluation method. The evaluation results show that the method is simple, convenient and reliable. It is widely used in other low permeability reservoir infilling areas.
