摘要(Abstract)：

综合利用岩心、测井、薄片、扫描电镜及分析化验等资料,分析准噶尔盆地莫索湾—莫北地区侏罗系下统八道湾组致密储层宏观、微观特征及质量主控因素。结果表明:该储层为典型深层低—特低孔、低—特低渗致密碎屑岩储层;砂体主要为浅水三角洲型前缘水下分流河道细粒、中—细粒岩屑类砂岩,成分成熟度和胶结物体积分数低,岩屑和塑性岩屑体积分数高;成岩作用主要包括破坏性压溶作用、胶结作用及建设性溶蚀作用。孔隙垂向上主要位于混合孔—孔隙稳定和次生孔—孔隙增加两个变化带;孔喉为中—细孔—细喉型,大小、分布、连通性及渗流能力较差。储层质量(物性)主控因素为沉积相带、成岩作用和异常压力,共同决定储层原始和现今物性。该研究结果为深化盆地深层致密油气储层勘探开发提供依据。
