摘要
通过对塔中地区构造解析,识别出多条具一定规模的NE向走滑断裂体系,主要活动时期为加里东末期—海西早期,其形成与加里东末期塔里木克拉通南、北两侧发生的强烈碰撞作用以及盆地基底存在的北东向构造有关。走滑断裂对碳酸岩储层改造、火山活动、圈闭形成、油气运移以及成藏有控制作用。
Several large scale strike-slip fault systems which are NE-trending are identified in Tazhong area by geostructural analysis,the main active time of the strike-slip fault systems was from the end of Caledonian to early Hercynian,the formation of the strike-slip fault derived from the collision on the south and north of the Tarim plate in the end of Caledonian,and it was also related to the NE-trending basement structure.The strike-slip fault systems control the reservoir re-formation,volcanic activity,trap formation and migration and accumulation of oil/gas.
