摘要

鉴于准噶尔盆地南缘地区已经成为新疆石油勘探的重要靶区,但由于其勘探程度低,四棵树凹陷的构造研究不够深入,无法进行彻底的油区构造分析,对进一步寻找油气圈闭造成了困难.文中对四棵树凹陷地质构造特征进行了详细的分析,将其分为五大构造体系:(1)四固南断裂构造体系;(2)四棵树—–西湖—–奎屯南背斜;(3)固尔图断裂构造体系;(4)艾卡西断裂构造体系;(5)卡因迪克断裂构造体系;然后分别对每个构造体系进行逐一解剖,即主要从地震剖面入手,一一进行地震地质剖面解释,将其划分为每个具体构造,讨论其形成的时期以及动力学特点.重点是建立四棵树凹陷的构造格架,为进一步四棵树凹陷的油气勘探提供了有力的证据.
The southern Junggar basin has become the important oil exploration area.Due to the under-prospecting,the structure of Sikeshu sag has not been fully studied,which obviously inspires the further probe into its oil reserve in this virgin land.This paper illustrates geological structure characteristics of the Sikeshu sag in detail,which divides the structure into five categories:(1) the fractured structure system of south Sigu;(2) anticline from Sikeshu to west lake and south Kuitun;(3) fractured structure of Guertu;(4) fractured structure of Aikaxi;(5) fractured structural of Kayindike.In this paper,each structural system is explained sequentially in the order of the section of seismic geology to manifest the detailed geo-structure,the age of formed structure as well as the dynamic characteristics.
