摘要： 准噶尔盆地西北缘前陆冲断带是自石炭纪晚期发育起来的大型叠瓦冲断系统, 克百冲断带为其冲断前锋构造带的中段。冲断前锋带的构造变形主要发生于早二叠世末, 侏罗纪构造活动趋于停止。被推覆体掩伏的下二叠统和石炭系具备良好的自生自储条件。前锋断裂带下盘的准原地系统中发育一系列断层转折褶皱、双重构造, 具备形成多种类型圈闭条件, 储集层岩性以火山岩和砂砾岩为主, 孔隙类型以孔缝为主, 受埋藏深度影响较小, 可形成自生自储油气藏类型。是准噶尔盆地西北缘下盘掩伏带的主要勘探目标之一。克百掩伏带的白碱滩背斜、百口泉背斜应作为首选的钻探目标。

Abstract: The foreland thrust zone in northwestern margin of Junggar basin is a large-scale imbricated thrust system developed since the Late Carboniferous, and Karamay-Baikouquan (Ke-Bai) buried structural belt is situated in the mid-sector of its front structural zone whose tectonic deformation started in the Late Permian and almost ceased in the Jurassic. The Lower Permian and Carboniferous underlying the thrust nappe possess good conditions for forming both source and reservoir in them. In the quasi-autochthonous system developed a series of double fault-fold structures in the lower block of the front faulting zone and conditions for forming various traps. The lithology of the reservoir is characterized by volcanic rocks and glutenites with pores and fissures or fractures. Less controlled by burial depth, the oil-gas pools with both source and reservoir could be formed. It is concluded that Ke-Bai buried structural belt is one of the targets for petroleum exploration in lower block buried zones of northwestern margin of Junggar basin, in which Baijiantan and Baikouquan uplifts should be as preferred targets for prospecting.

Key words: Junggar basin, northwestern margin, foreland thrust zone, Karmay-Baikouquan buried structural belt, exploratory target, domain
