  • 摘要:

    江汉盆地新沟嘴组下段Ⅱ油组广泛发育页岩与白云岩互层的烃源岩, 近期该层系页岩油勘探获得了重大突破, 但盐湖沉积背景下沉积的膏盐对于孔隙的影响制约了页岩油的勘探开发, 明确低膏盐富有机质岩相发育的控制因素对页岩油勘探具有重要意义。选取陈沱口凹陷的C1系统取心井作为研究对象, 通过岩心及岩石薄片的观察鉴定, 全岩矿物组成质量分数、有机碳及地球化学元素含量测定, 对C1井新沟嘴组下段Ⅱ油组的岩相类型、沉积环境和有机质富集主控因素进行了系统研究, 建立了适合江汉盆地新沟嘴组盐湖相岩相划分方案和沉积模式。结果表明: C1井新沟嘴组下段Ⅱ油组共发育4类7种岩相, 分别为富碳细纹层状白云岩、富碳粗纹层状白云岩、含碳块状白云岩; 富碳细纹层状混合质页岩、富碳粗纹层状混合质页岩; 含碳粗纹层状粉砂岩; 贫碳块状膏盐岩。古气候、古盐度与古氧化还原协同演化控制了岩相发育的多样性, 有机质富集的主控因素为还原性古水介质环境。页岩油勘探有利岩相为富碳(含碳)粗纹层(细纹层)状白云岩(混合质页岩), 有利岩相的沉积环境为咸水、还原的半深湖环境。陈沱口凹陷新沟嘴组下段Ⅱ油组富有机质岩相发育控制因素及其沉积环境的揭露, 可为江汉盆地相关凹陷新沟嘴组页岩油勘探提供借鉴和参考。
