Based on the theoretic model, formation stress may be derived from constraint inversion method with use of imaging data of borehole collapse and hydaulic fractures, in such away that not only the maximum horizontal stress profile but also the minimum one can be obtained, and further the formation breaking pressure, which is helpful to borehole stability analysis and fracturing design.
新方法基于成像测井资料对井壁破坏形式的准确判别来约束反演地层应力大小,不仅可以得到最小水平应力剖面而且可以得到最大水平应力剖面,由此计算出地层破裂压力和坍塌压力剖面,有助于井眼稳定性分析和压裂设计。

Through analyzing frecuring data of many wells in the Ordovician formation in central Tarim basin,it is found that formation stress information in pressure-time curves obtained from the fracturing data may reflect the true formation stress.
分析塔中工区奥陶系地层多口井的压裂施工资料,发现其压裂施工时记录的压力-时间曲线包含的地层应力信息能够真实地反映实际地层的地层应力大小,将该地层应力信息提取和分析后,较为准确地计算地层最小水平主应力;将该计算结果用于标定摩尔-库仑准则的地层应力测井计算结果,可确定摩尔-库仑准则的地层应力测井计算模型中内摩擦角参数,求得了塔中奥陶系地层岩石平均内摩擦角为21。
