摘要/Abstract

摘要： 在对陆梁隆起的5个沉积-构造层和断裂系统分析的基础上, 探讨了早二叠世以来陆梁隆起基底断裂对盖层多期沉降构造格局的控制作用。初步确定了陆梁隆起的断裂组合由三个泉-陆南和滴水泉-石西右旋斜冲走滑断裂带组成。陆梁隆起带盖层断裂受控于基底断裂, 总体构成近东西向的以三个泉斜冲走滑系统和滴水泉斜冲走滑系统为主干的弧形树型断裂系统。将陆梁隆起划分为2个一级构造单元、6个二级构造单元、15个三级构造单元、26个四级构造单元。认为三个泉和滴水泉深部岩石圈走滑断裂系统为油气聚集提供了通道; 沿北东向断裂的上盘形成一些呈右行展布的小幅度褶皱构造, 可成为好的储油空间, 陆梁隆起带的油气运聚规律为树型热动、南北运移和分段沿梁聚集。

Abstract: Based on the analysis of five sedimentary-tectonic zones and fault systems, this paper discusses controls and framework of the Early Permian basement fault on depression of multi-stage cap rocks in Luliang uplift of Junggar basin. It is determined preliminarily that the fault system of Luliang uplift is composed of Sangequan-Lunan and Dishuiquan-Shixi dextral oblique strike-slip fault belts. The caprock fault is controlled by the basement fault in Luliang uplift, forming the arcuate tree type fault system dominated by Sangequan and Dishuiquan oblique strike-slip systems near EW direction. Luliang uplift can be classified into 2 first-class structural units, 6 second-class structural units, 15 third-class structural units and 26 fourth-class structural units. Sangequan and Dishuiquan deep lithospheric strike-slip fault systems could be as pathways for hydrocarbon accumulation. Some small folds in dextral distribution along the upper wall of NE faults might become spaces for petroleum accumulation. The regulation of hydrocarbon migration and accumulation in Luliang uplift assumes tree type thermal supplies from deep crust, oil-gas migration from south to north and segmented accumulation along the uplift.

Key words: Luliang uplift, structural framework, fault system, hydrocarbon accumulation
