TECTONIC CHARACTERISTICS AND HYDROCARBON PROSPECTS OF SOUTHEAST TARIM BASIN
-
摘要: 地层接触关系和区域沉积特征表明,塔里木盆地东南部同塔里木盆地整体一样,经历了古生代地台、中生代断陷、新生代拗陷3个发展阶段。本区自早古生代以来,曾发生过5次明显的区域性构造运动,据基底埋深、深断裂、地层厚度和分布等特征,可将本区分为2个一级构造单元和8个二级构造单元。油气远景区主要分布于且末以西。Abstract: Stratigraphic contact relations and regional depositional characteristics imply that the southeastern part of Tarim Basin, like the whole Tarim Basin, has undergone three evolutional stages——Paleozoic platform, Misozoic fault depression and Cenozoic depression.Since early Paleozoic era, five distinct regional tectonic movements have occurred in this area. According to the characteristics of basement depth, deep faults and Stratigraphic thickness and distribution, Southeast Tarim Basin can be divided into two major tectonic units and eight secondary structural units. The prospective hydrocarbon blocks lie to the west of Qiemo.
