摘要(Abstract)：

利用地震、测井、岩心等资料,研究楚—萨雷苏盆地南哈萨克区块下石炭统的层序地层、沉积相、沉积演化及其对有利储层的控制.结果表明:下石炭统自下而上可划分为4个三级层序,每个层序主要由海侵和高位体系域构成.识别主要沉积相类型包括蒸发台地、开阔台地生物礁、礁—滩复合体、滩间海、局限台地澙湖、淹没台地或深水台地等,高位体系域以开阔台地相为主;海侵体系域以发育局限台地相为主,中部的SQ3发育深水—淹没台地相,上部SQ4的顶部发育蒸发台地相.总体上,由南向北可划分潮缘带—局限台地、开阔台地高能滩、台地边缘礁、滩、浅海—半深海等沉积相带.沉积、层序对储层具有明显的控制作用,台地边缘高能相带为有利的储层相带,三级或四级层序界面附近,储层质量最好,储层孔隙度大于10%.
