摘要： 通过对牙哈构造带三维地震资料的精细解释,认为寒武纪与中、新生代断裂活动差异明显,平面上主要呈近东西向、北西西向、南北向以及北东向展布,其中近东西向的牙哈大断裂为主控断裂,主要经历区域挤压应力下的逆冲推覆、应力松弛阶段的负向反转以及压扭向张扭转化的左旋走滑等4 阶段的构造作用,沿断裂走向形成一系列的断背斜构造。断裂活动控制着寒武系不同年代潜山的分布范围、有利储集层发育以及油气分布,同时也是古近系油气运聚的通道。

Abstract: The detailed interpretation of 3D seismic data of Yaha structural belt shows that there exist obvious differences of fault activity between the Cambrian and the Meso-Cenozoic. Its plane distribution mainly occurs in four directions: near EW, NWW, SN and NE, of which near EW Yaha fault is dominant fault and has undergone such tectonism stages as thrust nappe, negative inversion and left-lateral strike-slip process from compresso-shear to transtension, and along its strike developed a series of faulted anticlines. These fault activities control the distribution of Cambrian buried hill, the development of favorable reservoirs and the migration of oil and gas. Also, they are pathways for hydrocarbon migration and accumulation in Paleogene in this area.

Key words: Tarim basin, Cambrian, buried hill, fault
