摘要(Abstract)：

分析克拉玛依油田六中区克下组沉积环境,指出不同沉积微相储集性能与含油性之间关系,为后期开发调整提供依据.研究野外露头、岩心及化验资料等,在确定研究区沉积环境基础上,分析沉积微相展布特征,指出沉积微相与含油性之间关系.结果表明:研究区为以辫状河为主的冲积扇,主要发育扇中和扇缘亚相,依据各微相类型的岩性、沉积构造及测井曲线形态等特征,将扇中亚相分为辫流水道、辫流砂岛和漫流带等微相,扇缘亚相分为径流水道和泛洪带微相.不同沉积旋回内沉积微相的空间展布规律:下部中期旋回砂体呈连片状,厚度大,延伸范围广;中部中期旋回砂体以宽带状为主,厚度较薄,延伸范围较窄;上部中期旋回砂体以窄条带状为主,厚度薄,延伸范围窄.储层物性稍差的侧缘—漫流带及砂体井控程度较低的窄条带状砂体是剩余油挖潜的主要对象.
