| 摘 要： | 根据前人对东海西湖凹陷的地质研究成果和实际资料,运用地质动力学的基本观点,从西湖凹陷构造形变特征分析入手,探讨了西湖凹陷古构造应力场的边界条件和古应力的作用方式,用古构造图和岩石力学参数描述其地质模型,采用弹性力学模型,运用平面应力有限元数学方法选取适当的力学参数,对中新世的古构造应力场进行了数值模拟,并据其结果对西湖凹陷的油气有利聚集区作出了预测。

| Abstract: | According to predecessors geological research results and actual data,using geomechanics opinion,combined with its structrual deformation character,the boundary condition and stress acting behaviors of the Xihu depression were analyzed in the Miocene epoch.Its geological model was described by paleostructure map and rock mechanics parameters,and the tectonic stress field in the Miocene was modelled by elastic mechanics model and finite-element method for plane stress.The favorable positions for hydrocarbon accumulation were predicted in accordance with the modelling results. |

| Keywords: | paleotectonic stress field plane stress finite-element method numerical simulation Miocene the Xihu Depression |
