| 中文摘要:通过对稳定沉降地区与山前挤压构造区的地球物理测井信息的深度域特征进行理论分析和对比，提出了一种基于测井信息计算最大主地应力的统计模型法。应用该方法对塔里木盆地库车地区地应力进行了实际计算，其结果与实验结果相符，同时利用椭圆井眼法确定最大主应力方向。最后，对山前挤压构造区的地应力分布与油气藏分布关系进行了探索。 |

| A New Method for Studying Ground Stress in the Structural Compressive Area of a Foreland |

| Abstract:Through a comparison between distribution characteristics of logging data in the structural stable field and those in the structural compressive field, the authors put forward a new method for determining maximum horizontal in situ stress based on statistical analysis of resistivity and acoustic slowness time. The method and the model were used to calculate in situ stress in the Kuche oil field of Tarim basin. The calculated stress coincides with the result of the acoustic emission experiment. The azimuth of the maximum compressive horizontal principal stress was also obtained by using enlarged well bore breakouts in the area. The research shows an intimate relationship between the stress distribution and the distribution of petroleum pools in the area. |
