晚三叠世是四川盆地形成演化的起点，其地层是油气勘探的一个重要目标层。通过对四川盆地晚三叠世动力学特征的分析，建立其动力学模型（构造应力（叠加）场模型），采用有限单元法进行模拟，其结果显示，四川盆地晚三叠世构造应力条件以ＮＷ—ＳＥ方向的挤压占主导。构造动力是油气运聚的驱动力，驱使油气运移的动力来自构造应力场，通过模拟认为，四川盆地晚三叠世构造应力场形成的圈闭为模拟计算的最大应力值２．０～４．０ＭＰａ之间的区域。
Late Triassic is the starting point for the evolution of the Sichuan Basin. Its formation is an important target for hydrocarbon exploration. Through the analysis of the dynamics of the Late Triassic in the Sichuan Basin, a dynamic model (tectonic stress (superposition) field model) was established and simulated by the finite element method. The results show that the Late Triassic tectonic stress in the Sichuan Basin The squeeze in the NW-SE direction dominates. The tectonic motive force is the driving force of hydrocarbon migration and accumulation, and the driving force for the hydrocarbon migration comes from the tectonic stress field. According to the simulation, the traps formed in the tectonic stress field of the Late Triassic in the Sichuan Basin are calculated as the maximum stress 2.0 ~ 4 .0MPa between the area.
