摘要(Abstract)：

为明确准噶尔盆地乌尔禾—风南地区百口泉组成岩作用及成岩相,根据岩心分析化验数据,确定百口泉组储层物性特征;根据岩石薄片和扫描电镜观察结果,确定百口泉组成岩作用类型及强度;根据X线衍射结果,确定黏土矿物组分及体积分数;根据岩心薄片及其测井曲线特征,采用"物性加主控因素"分类方法,划分成岩相类型并建立各成岩相测井响应特征,确定成岩相分布规律,预测有利成岩相分布区。结果表明:百口泉组储层主要经历压实作用,碳酸盐、黏土矿物、黄铁矿、硅质胶结作用,以及长石、石英溶蚀作用。储层可划分为5种成岩相类型,即特低孔渗杂基充填相、中孔渗弱压实强溶蚀相、低孔渗强压实强溶蚀相、特低孔渗方解石胶结相和特低孔渗强压实相,其中中孔渗弱压实强溶蚀相和低孔渗强压实强溶蚀相为有利成岩相。中孔渗弱压实强溶蚀相主要分布于乌009—风4井区,低孔渗强压实强溶蚀相主要分布于乌2—风南7—夏75井区。该分析结果可为研究区优质储层预测提供地质依据。
