摘要(Abstract)：

根据三维地震、钻井新资料、岩心观察及构造沉积学分析,研究银额盆地拐子湖凹陷断陷早期发育的含油层系巴音戈壁组的构造与沉积特征。结果表明:拐子湖凹陷具有明显的断陷、坳陷双重地层结构,经历断陷期、断坳转换期、坳陷期3个构造演化阶段。燕山Ⅲ幕构造活动影响盆地断陷初期的盆地结构及巴音戈壁组沉积充填特征;巴一段沉积早期,区内发育断层数量多,呈现多个局限地堑、半地堑并存的盆地结构;物源多方向供给,凹陷整体发育冲积扇、扇三角洲—湖泊沉积体系;巴一段沉积晚期,边界断层活动剧烈,在A井西侧发育的扇三角洲沉积物由于断块掀斜而形成滑塌重力流沉积;巴二段沉积期,边界断层持续活动,盆内次级断裂活动减弱,形成典型的半地堑湖盆,凹陷以扇三角洲前缘—砂坝—浅湖沉积为特征。研究结果为揭示勘探新区构造、沉积演化及油气储层评价提供地质依据。
