摘要
本文在分析塔里木盆地塔中地区各种地质、地球物理资料的基础上,根据构造地质剖面图建立了三维有限单元模型,对三维构造应力场进行了模拟计算。结果表明,塔中地区现今仍有活动的几条断裂使局部构造应力场复杂化,控制了油气的再次运移,使油气重新调整成藏。总的来说,该区断裂在新生代的活动有利于油气沿断裂带运聚。
This paper, based on the interpretation to geological and geophysical data in Tazhong area of Tarim basin, sets up a 3D finite element model by virtue of tectono-geological sections, and then simulates the 3D tectonic stress field in that area. The result obtained shows that some presently active faults complicate the local tectonic stress field, which control the hydrocarbon re-migration and re-accumulation there. In summary, hydrocarbon migration and accumulation along the faults is benefited by the action of these faults in the Cenozoic era.
