讨论了分层应力的计算的多种模型,单轴应变模型、构造应力/应变边界模型、平面应变模型等,优选了在实际应用中具有较好的预测效果的平面应变模型。对济阳坳陷基山砂岩体的商×井的分层地应力与岩力学石参数进行了计算,研究结果表明,通过优化分层地应力模型优选及岩石力学参数,可以控制裂缝在油层内延伸。 Several models of stratified stress calculation, uniaxial strain model, tectonic stress / strain boundary model and plane strain model are discussed. The plane strain model with good prediction effect in practical application is preferred. The stratigraphic geostress and rock mechanics parameters of X × Well in Jishan sag body in Jiyang Depression are calculated. The results show that by optimizing stratified stress model optimization and rock mechanics parameters, it is possible to control the fracture extension in the reservoir .
