摘要
建立了苏里格气田的地质构造模型,利用有限元分析方法,对苏里格气田进行了地应力场有限元反演和三维构造应力场的数值模拟,模拟出区域最大主应力、最小主应力、最大剪应力和岩石应变能的分布规律,进而预测区域天然裂缝的分布规律,同时分析了构造应力场在水平井压裂中对水力裂缝启裂方位、裂缝规模的控制作用等,为气田水平井整体开发井网部署及压裂设计提供借鉴。
Structural geologic model of Sulige gas field has been established.By using the finite element analysis method,the paper makes a study on the stress field inversion and threedimensional finite element numerical simulation of tectonic stress field,and gains the maximum principal stress,the minimum principal stress,the maximum shear stress and strain energy distribution of simulation region,and then to predict the regional natural fracture distribution.After the analysis of the structure stress field effect in horizontal well fracturing to hydraulic fracture initiation azimuth,fracture scale has been made.Finally through the micro-fracture four-dimensional vector scanning fracture monitoring data for inspection,the guidance of the gas field horizontal wellintegrated development well pattern deployment and fracturing design has been provided.
