针对特低渗透油藏特点,以某实际油藏为基础,进行了合理压裂水平井直井联合井网形式研究;运用典型地质模型和数值模拟方法,采用局部网格非均匀加密和等连通系数法对裂缝网格进行了处理;综合对比分析了压裂直井注水-压裂水平井采油、压裂水平井注水-压裂直井采油、水平井注水-压裂水平井采油、直井注水-水平井采油、直井注水-直井采油、压裂直井注水-压裂直井采油等6种井网在不同井距排距的开发效果,优选合理井网形式。研究结果表明,该特低渗透油藏开发合理井距排距为200 m ×160 m ,应用压裂直井注水-压裂水平井采油井网可以取得较好的开发效果。

The rational well pattern for fracture horizontal and vertical wells in ultra-low per-meability reservoir has been studied by using typical geologic model and numerical simulation methods for a certain oilfield .Using non-uniform encryption local grid and the same connec-tivity method for fracture grid processing .Compare and analyze the development effect of six well patterns ,fractured vertical injector and fractured horizontal producer pattern ,fractured horizontal injector and fractured vertical producer pattern ,horizontal injector and fractured horizontal producer pattern ,vertical injector and horizontal producer pattern ,vertical injector and vertical producer pattern ,fractured vertical injector and fractured vertical producer pat-tern ,at different well interval and array spacing ,to choose the rational well pattern .The re-sults show that the rational well interval and array spacing is 200 m × 160 m and the rational well pattern which could receive a anticipated development effect is fractured vertical injector and fractured horizontal producer pattern .
