摘要(Abstract)：

利用钻井、测井、录井和地震等资料,分析岩石结构构造和古生物,研究准噶尔盆地车排子地区白垩系沉积相发育特征.结果表明:研究区白垩系主要发育扇三角洲相和湖相,可以划分为扇三角洲平原﹑扇三角洲前缘和滨浅湖亚相,以及水上分流河道、漫滩沼泽、水下分流河道、水下分流河道间、席状砂、泥滩、滩坝微相.总体为滨浅湖沉积背景,西北部为隆起区,提供物源,向东、南方向逐渐演化为宽缓的斜坡,碎屑物质主要沉积于斜坡的滨浅湖区.从清水河组到连木沁组沉积范围不断往西南部扩大.受湖平面升降、气候变化、沉积物供给等因素的影响,扇三角洲砂体规模较小,滩坝砂体广泛发育,砂体紧靠生油凹陷,是油气聚集的有利场所,易于形成下生上储型油藏,是油气勘探的重要目标.
