摘要
近年来,非常规油气勘探开发取得重大突破,大大拓展了储层研究内容,有力推动了储层研究方法的创新。对储层孔隙结构和孔渗特征的认识因新技术的应用而拓展,从常规尺度到纳米级孔隙,从低孔低渗到超低渗储层。文章在介绍和比较孔隙表征的多种方法基础上,根据孔隙结构和储渗特征将储层分为大—中孔高渗储层、微孔低渗储层、纳米孔超低渗储层和复合型孔隙储层4类,并针对不同类型的储层探讨了各个表征方法的优缺点和有效范围,提出了适用于不同类型储层的表征方法组合,针对复合型孔隙储层提出了分区—分层表征技术。此外,文章还探讨了这些表征技术在孔隙成因、孔隙内壁表面结构、充填物特征等研究方面的应用,将储层表征技术从储层品质研究延伸到成因研究,为更加全面综合认识和评价储层提供参考。
