摘　　要：根据地震资料剖析了塔中低凸起的结构特征及其演化史 .结果表明 ,塔中低凸起是塔里木早古生代盆地经晚加里东—早海西期构造改造作用最终形成的的下古生界残余古隆起 ,经历了初始形成、定型演化和埋藏三大演化阶段 .隆起区断裂构造发育 ,主要存在北西、北西西和北东东两大构造方向 ,北西、北西西向断裂控制了低凸起的结构特征 ,北东东向构造对北西、北西西向断裂在走向上具有分段特征 .目前 ,高产油井多集中在北东东向构造与北西或北西西向断裂相交部位或附近 ,进一步深入研究这两组构造 。In order to guide the exploration practice in this area, the structural characteristics and the evolution of Tazhong low uplift are analyzed based on seismic data. It is held that Tazhong low uplift is an ancient uplift mainly formed during late Caledonian and early Hercynian movement. Its evolution can be divided three stages: initial formation, final formation and burial stages. There mainly exist NW, NWW and NEE-trending faults in Tazhong low uplift. NW and NWW-trending faults determine the framework of Tazhong low uplift. NEE-trending faults have sectionalizing effect on NW, NWW and NEE-trending faults. The exploration result shows that high oil production wells are mostly located in the intersecting areas of NW and NWW-trending faults with NEE-trending faults. It is very important to oil and gas exploration to further study the two group structures.
