摘　　要：水平段的长度和避水高度是底水油藏水平井设计的关键技术参数,合理的取值可以使产量和成本实现最优、可以有效提高开发效益。依据模糊理论建立水平段长度优化模型,并结合水平井无因次产量和临界产量与避水高度的变化分析,实现了X构造Es31油藏水平井优化设计。Horizontal interval length and standoff were the key parameters of horizontal well design for a reservoir with bottom water.The reasonable values could optimize oil production rate and cost of horizontal well.It can improve development benefit effectively.According to fuzzy theory,an optimized model of horizontal interval length is built up in combination with dimensionless production rate and critical oil production rate versus standoff of horizontal wells,the optimized horizontal well design of E31 Reservoir with bottom water in X oilfield.
