江汉盆地陈沱口地区结构构造及演化特征

On Characteristics of Chentuokou Tectonic Evolution in Jianghan Basin

通过对陈沱口地区重新处理二维地震资料及新采集处理三维地震资料的精细解释,明确了陈沱口地区结构构造演化特征及其与周缘构造带的关系。研究区总体表现"三洼两隆两斜坡"的构造格局,先后经历多期主要构造演化,形成三组断裂和多种组合样式,局部圈闭较发育,主要以断块类型为主,具有一定的勘探潜力。

Detailed interpretation of rehandled 2D seismic data and newly collected and handled 3 Dseismic data in Chentuokou Area makes clear the relationship between its tectonic evolution characteristics and its margin tectonic belt.The research area displays generally structural framework of three hollows,two bulges and two slopes.Gone through multi-phase major tectonic evolution,it forms three groups of faults and multiple combination patterns with well-developed local trap which consists mainly of fault block type and has certain exploration potential.
