Model of fracture initiation of the refracturing deep wells
深井重复压裂裂缝起裂模型
The fracture initiation of fractured ERW differ from those of the vertical and the conventional directional wells, the initiation mode is not only relative to the well trajectory (deviation and azimuth angle) but also the in-situ stress azimuth.
大位移井水力压裂裂缝起裂与直井、普通定向井有显著差别 ,其起裂模式不仅与井眼轨迹 (井斜角、方位角等 )有关 ,而且还与地应力方位密切相关。
The mathematical model of the fracture initiation pressure is established,and according to the solution of the model,the conclusions can be drawn that if wellbore azimuth angle is different,the effects of vertical principal stress and minimum horizont.
