塔里木盆地中央隆起区寒武纪构造特征及主要油气领域
|
摘要
基于塔里木盆地中央隆起区的地震剖面以及钻井等资料,研究了中央隆起区寒武纪的构造特征及演化。从震旦纪开始,塔里木盆地进入了区域伸展的构造背景,早-中寒武世继承震旦纪的构造格局,发育一系列的箕状断陷,控制了中央隆起区小范围内地层的发育与沉积相带的展布。半地堑的分布范围与塔里木盆地的磁异常区相一致,说明半地堑的形成受基底隐伏断裂影响。早-中寒武世之后以挤压—挠曲作用为主,对箕状断洼起到重塑的作用。结合中央隆起区寒武系的基本成藏条件,指出了中央隆起区有利的油气领域,主要包括:构造圈闭领域、隆起高部位、古城墟隆起的上寒武统以及断洼沉积的岩性地层圈闭。
Based on seismic sections,the drilling and other data of central uplift area,the structural characteristics and evolution of central uplift area in Cambrian has been studied.Tarim Basin entered the environment of regional extension from Sinian,in the Early and Middle Cambrian, the basin inherited the tectonic framework of Sinian and developed a series of half graben rifts, which controlled the development of strata and the distribution of sedimentary facies of central uplift area in a small range.The distribution range of half grabens was consistent with magnetic abnormal area of Tarim Basin,which showed that the formation of half grabens was controlled by the buried basement faults.After the Early and Middle Cambrian,the basin was in the environment of compressive bending,half graben rifts were builded.Combined with Cambrian basic reservoir formation conditions of central uplift area,The favorable hydrocarbon domains were pointed out,which mainly included domain of structural traps,high part of uplift,the Upper Cambrian of Guchengxu uplift and lithologic-stratigraphic trap in the half graben.
