摘要: 根据沉积层序、构造变形样式及地层接触关系,将黔南拗陷沉积盖层划分为3大构造层,并重新划分黔南拗陷的构造区划。通过野外地质调查并结合地球物理资料,按黔南拗陷断裂特征及其不同部位构造变形强度的差异,将黔南拗陷划分为叠瓦冲断变形区和褶皱冲断变形区。黔南拗陷具有东西分带、上下分层的特点。依据各构造单元变形强度等相关要素的评价,优选出长顺凹陷为相对稳定的油气保存区,结合该区的石油地质条件,指出长顺凹陷为下步油气勘探的有利区带。

Abstract: Southern Guizhou Depression has experienced three basin ages,which are Proto-Tethys,Pateo-Tethys and Neo-Tethys.According to the lithologic sequence,structure style and stratigraphic contact,the sediment cover is divided into three structural layers and the building units are redistributed.According to the feature of the faults and divergences of the tectonization in different part of the depression,it is divided into imbricate thrusting distorted area and fold thrust distorted area.Based on field geologic survey,earth physical data and the evaluation of the intensity of ectonization in the building units,the Changshun sag is optimized as the beneficial structure petroleum preservation area.Considering the geologic condition,it can be concluded that the Changshun sag is the exploration prospect area of the Southern Guizhou Depression.

Key words: Southern Guizhou Depression, tectonic sequence, fracture characteristics, tectonic deformation, hydrocarbon conservation
