祁连山北缘深部弧形褶皱—逆冲带及其油气勘探前景
Chinese Journal of Geology（2016）
Abstract
祁连山北缘—河西走廊西段位于青藏高原东北缘,是新生代陆内构造活动最强烈地区.基于野外构造观测、横跨山前及前陆盆地区的三维地震构造分析与解释,结合地震地质属性提取分析,识别出祁连山北缘—酒泉盆地西段窟窿山—柳沟庄带隐伏的弧形褶皱—逆冲带,该弧形构造是造山带基底逆冲构造楔体垂向差异抬升与向前陆方向差异运动的产物;该弧形结构控制本区下白垩统地层裂缝发育、分布与破裂强度,并与本区先期断裂、裂缝带产生构造叠加效应,形成弧形构造“中央强裂缝发育带”,是形成构造裂缝型油气藏的有利区域.
