摘　　要：通过地面地质和大量高质量的地震剖面的解释，提出塔里木盆地西南坳陷构造类型可分为２大类６亚类１０小类：①基底卷入型：包括基底逆冲、走滑扭动、逆冲与扭动复合、基底挠曲；②盖层滑脱型：包括张性断陷、双重逆冲、叠瓦式逆冲、滑脱背斜、重力滑动、断弯背斜构造。目前已在滑脱背斜和双重构造上部找到了油田、推测各种滑脱构造、扭动构造中所伴生的褶皱－断裂系统和基底挠折构造、基底卷入的背斜是油气勘探中的远景区。Through the studies of surface geology and interpretation of great numberof high-quality seismic sections,structural type of the southwest depression in Tarimbasin may be divided into two major types,six subtypes and ten small types. The majortypes are:(1) basement rolling-in type,including basement thrust,strike-slip torsion,thrust-torxion compiex and basement flexure;(2)caprock detachment type, involving tension fault depression, dual thrust,imbricate thrust, detachment anticline, gravity slidingand bend-faulted anticline. An oil reservoir has recently been discovered in detachment an-ticlines and the upper of dual strticture. Therefore, it is estimated that various detachmentstructures,folded fault svstems associated with torsion structtire,basement flexure struc-ture and basement rolling-in anticline are prospective area for oil and gas exploration in Tarim basin.
