| 摘 要： | 塔里木盆地塔中地区经历了多期构造变形和演化,构造样式复杂多样,正确厘定寒武系盐下构造样式对寻找有利勘探圈闭至关重要。结合现有钻井资料,对塔中三维区地震剖面进行精细构造解析,主要根据构造变形特征,将寒武系盐下白云岩构造划分为拉张、挤压、走滑、古潜山、局部反转和复合构造样式六大类,进一步可细分为多个亚类。综合分析认为研究区内发育与断裂相关的断块和断背斜圈闭将是下步勘探的有利目标。

| Abstract: | Tazhong area of Tarim Basin has complex and diverse structural styles for experiencing several tectonic deformation and evolution. It is significant to correctly determine Cambrian subsalt structural styles to find favorable exploration traps. Combined with existing drilling data, the seismic profile of Tazhong 3D area is finely analyzed. Based primarily on structural deformation, the structural styles of Cambrian subsalt dolomites are systematically classified into six categories, i.e. extrusion, stretching, strike-slip, ancient hill, local inversion and composite structural styles. These could be further subdivided. Comprehensive analysis shows that the traps of fault blocks and faulted anticlines will be the favorable Cambrian targets for further exploration in Tazhong area. |
