摘要(Abstract)：

在明确泥质体积分数、粒度为准噶尔盆地玛湖凹陷西斜坡区三叠系百口泉组低孔低渗砂砾岩储层质量主控因素基础上,结合储层—测井资料,构建储层评价因子CZ,利用常规测井曲线判别砂砾岩储层质量(储集空间、渗流能力);根据储层—测井—地震资料,在波阻抗反演基础上,利用储层评价因子CZ进行地质统计学模拟储层反演,预测百口泉组优质储层的平面展布范围.结果表明,Ⅰ类储层CZ>8,储层质量最优,主要分布于玛132-玛13井一线,平面上叠置连片;Ⅱ类储层8>CZ>5,储层质量较优,多围绕I类储层边缘展布,主要分布于玛15、玛16、玛133井一带;Ⅲ类储层5>CZ>2,储层质量较差,主要分布于玛154、玛17井一带.该预测结果在油田现场井位部署中应用效果良好,部署8口井,Ⅰ类、Ⅱ类储层符合率分别为82%、85%.该方法为无核磁共振等特殊测井地区的低孔低渗砂砾岩储层分类评价及预测提供新思路.
