| 摘 要： | 构造应力演化研究是盆地模拟的重要环节,各期次构造应力分布情况决定了油气的运移方向.本文以溱潼凹陷地质演化的运动学研究为基础,合理地建立构造应力演化研究的初始模型和边界条件,运用非线性理论和塑性流动理论,以中部剖面ST365为例,模拟了各期次应力σx、σy和τxy的演化特征和图解,并对其油气地质意义进行了初步探讨.

| Abstract: | Studying stress evolution is a key link of basin simulation. The distribution of stress at each stage decided the migratory direction of petroleum and natural gas. Based on the researches of kinematic analogue in the Qintong depression，initial model and boundary condidons of simulation of structural stress evolution have been constructed appropriately. Taken ST365 profile as an example，the characteristics of evolution and the figures of stress σx，σy and τxy at all stages have been given by applying nonlinear theory and plastic flow theory to the study in this region，their geological significance of petroleum and natural gas has been explored. |
