HCL地区碳酸盐岩地层现今构造应力场研究

Study on the Present Tectonic Stress Field of HCL Regional Carbonate Formation

研究区域构造应力场的宏观分布特征,及其与油气运聚、裂缝发育程度和地层压力的关系,在油气勘探领域有着不可或缺的意义。本文通过有限元法数值模拟HCL地区的三维现今构造应力场,并与相干体数据、异常地层压力对比分析,认为构造应力是该区异常地层压力的主要因素之一。

It is meaningful to study the macro - distribution of the regional tectonic stress field, the relationship with carbohydrates migration, cracks development and formation pressure. In this paper,based on the finite element simulation of the current three-dimen- sional tectonic stress field of the HCL area, the comparative analysis of the coherence data and the formation pressure have been done, where it＇s concluded that tectonic stress is one of the main factors causing formation pressure in the area.
