| 摘 要： | 在张量理论的基础上．针对构造运动活跃地层或山前构造．分析了在真实主应力空间与人为假设空间(常规工程主应力)不一致的条件下。地应力测量和解析的不合理性．提出了通过特定的Kaisir效应实验确定山前构造地层地应力的可行方法．推导出的直井井壁稳定力学模型为山前构造的安全泥浆密度确定方法提供了理论依据。

| Abstract: | Based on tensor theory, in consideration of active tectonic movement formation or foothill structure, unrationality of in-situ stress measurement and analysis are analyzed under the conditions of real principal stress space not consistent with that of artificial space (conventional engineering main stress). A feasible method for determining in-situ stress in foothill structure is proposed under a special Kaisir effect experiment, the derived model for vertical wellbore stability mechanics provides a theoretical basis for determining safety mud density in foothill structure. |
