摘要
低渗透油藏整体压裂的开发效果是油、水井裂缝参数和井网井距等综合作用的结果。针对整体压裂多参数交互影响,以初期产量、采油速度等指标表征各生产时期影响,选用正交实验表设计以井距和油、水井裂缝参数为实验因素的正交实验方案,通过极差分析得到最优方案。基于优化结果设计施工井的产量明显优于邻近产量,表明正交实验法适用于整体压裂参数优选。
The Development effect of integral fracturing in low permeability reservoir not only depends on each single factor,but also relates to comprehensive effect of well spacing and fracture parameters of production and injection well.In the light of actual situation of interaction effect between integral fracturing parameters,the cross experimental method is used to optimize integral fracturing parameters,and initial production,oil recovery rate and other two index factors are elected.Based on the result,the initial production of an implemented experimental well is much better than the other two production wells.Therefore the cross experimental method is confirmed to be fit for optimization of integral fracturing.
