摘要/Abstract

摘要： 通过地震、非地震和野外地质调查资料的分析,根据构造和沉积特征,把上新世以来的塔东南盆地由西至东分为3部分:西段民丰凹陷为扭压盆地;中段为且末凸起,古近系不整合覆盖于元古界变质岩之上;东段瓦石峡凹陷为小型前陆盆地。认为塔东南盆地经历了晚古生代的边缘海沉积阶段、侏罗纪-早白垩世断-拗沉积阶段、古近纪-中新世拗陷沉积阶段、上新世-现今的压扭盆地和前陆盆地沉积阶段。上新世以来盆地构造变形的东西分段是由不同的应力机制和应力强度引起。瓦石峡凹陷山前带发育冲断推覆构造,侏罗系烃源岩增厚有利于油气成藏。

Abstract: Through the analyses of seismic, non-seismic and field geologic investigated data, based on the structural deformation and sedimentary characteristics, this paper divided the southeast Tarim basin into three parts from west to east since Pliocene: Minfeng sag (compression-shear basin), Qiemo swell (Palaeogene formation overlying Proterozoic metamorphic rock with unconformity) and Washisha sag (foreland basin related strike-slip fault). It is considered that southeast Tarim basin has experienced several structural evolution stages: marginal sea in late Paleozoic, fault depression-depression from Jurassic to early Cretaceous, depression from Palaeogene to Miocene, compression-shear basin of Minfeng sag and foreland basin of Washisha sag from Pliocene to now. Different stress mechanisms and stress strengths resulted in the structural deformation characteristics of different segments in E-W direction since Pliocene. In the piedmont belt of Washixia sag developed thrust nappe which leaded to incrassation of Jurassic source rocks, being favorable for hydrocarbon accumulation in this area.

Key words: southeast Tarim basin, structural evolution, structural framework, dynamic mechanism
