Abstract

Abstract: The 3-D geological model is set up based on the structure and the strata of the Tarim basin. The contemporary tectonic stress field is calculated by using the 3-D finite element method. The different tectonic stress field features at different depths which are caused by both tectonic force and gravity force and the relation between the stress field and hydrocarbon accumulation are analyzed.

Key words: Stress field, Numerical modeling, Basin, Tarim

摘要： 据塔里木盆地结构和盆地地层资料建立了盆地三维地质模型,用三维有限单元方法计算模拟了塔里木盆地现代构造应力场。分析了在构造力和重力共同作用下,盆地由浅至深各构造层应力变化特征,并研究了盆地内油气藏聚集与地应力场的关系。
