摘要
四川盆地东北部由于力学环境复杂且不稳定,因而形成了较为特殊的构造形迹组合,特别是其在平面上构造形迹变化更加特殊。构造形迹是古地应力场综合作用的结果,本文从现有的构造形迹出发,结合构造演化史,进行构造几何学特征分析,进而探讨构造形迹在平面上变化的原因,并在地质分析的基础上,对其正确性进行了验证。同时指出在该区进行天然气勘探的主要方向。
Because the geomechanical environment in the northeastern area of Sichuan basin is complicated and unstable,the combination of structural features is special,especially the planar structural feature.Structural feature is the outcome of the comprehensive action of paleo-terrestrial stress fields.Combining present structural features with tectonic evolutionary history,this paper analyzes the geometrical characteristics of structural features,approaches the reason of planimetric change of the structural features,and verifies the structural genesis on the basis of geologic analysis.At the same time,the paper points out the main explorative directions of natural gas in this area.
