摘要
There are favorable conditions to petroleum generation in the Guizhong Depression and its margin. The paper comprehensively and dynamically studied caprocks, tectonic actions, conditions of hydrocarbon preservation, and characteristics of groundwater chemical-kinetic behaviors responding to alterations of the hydrocarbon preservation condition during tectonic evolution of the basin. As a whole,the present condition of hydrocarbon preservation in the Guizhong Depression and its margin has been destroyed to some extent, while that in the central and western depression is comparatively good.
