本文运用板块构造理论对盆地演化历史进行了初步分析,认为盆地早期属弧后盆地,新生代转化为碰撞山前盆地。结合地质和物探资料将盆地划分为七大构造单元,即库车坳陷、北塔里木隆起、塔东坳陷、巴楚隆起、西南坳陷、塘古巴斯坳陷和东南断块隆起。其中除西南及库车坳陷已发现油气田外,塔东坳陷面积大,上第三系厚度较薄,构造类型多,又属地慢隆起区,可能有较高的热流值,有利于油气的生成和演化,是油气资源勘探有利地区。 In this paper, the tectonic evolution of the basin was used to make a preliminary analysis of the evolution history of the basin. It is believed that the basin was originally a backarc basin and a Cenozoic into a collision piedmont basin. According to the geologic and geophysical data, the basin is divided into seven structural units, that is, the Kuqa Depression, the North Tarim Uplift, the Tadong Depression, the Bachu Uplift, the Southwest Depression, the Tonggoubas Depression and the Southeast Uplift. In addition to the discovery of oil and gas fields in southwestern and Kuqa Depression, the Tadong Depression is large in area and thin in the Upper Tertiary, with many tectonic types and moderate uplift areas, which may have higher heat flow values, which are favorable for oil and gas Generation and evolution, is a favorable area for oil and gas exploration.
