【摘要】 为了满足油气勘探的需要,利用二维地震资料对汤原断陷进行了详细的构造研究,选取典型地震剖面进行了构造发育史分析.综合研究认为汤原断陷发育的断裂主要有北东和北西2个方向,北东向断层控制着断陷的走向和次级构造带的走向,使汤原断陷呈东西分带的特点;北西向断层与北东向断层相互切割,使汤原断陷呈现南北分块的特点.汤原断陷现今构造特征总体为西高东低、南高北低,断陷经历了3个演化时期和6个演化阶段.更多还原

【Abstract】 Using the two dimension seism survey,this paper deals with the tectonic characteristics and analysis the history of tectonic evolvement to the chosen classic seism surveys to meet the need of hydrocarbon exploration.The result of research shows that Tangyuan rift developed NW and NE two dimension rifts and the NE dimension rift controlled the dimension of Tangyuan rift and its sub-tectonic belts.The NW and NE dimension rifts cut each other and caused Tangyuan rift to exist in several blocks from north to south.The characteristics of tectonic in Tangyuan rift is that the west part is higher than the east part and the south higher than the north today.This rift had undergone three periods of development and six phases of evolvement.更多还原
