摘要(Abstract)：

乌石凹陷东区主要储层流二段、流三段分别发育三角洲和扇三角洲相沉积储层,储层物性包括高渗、中渗及低渗,非均质性强,产能差异大.采用常规物性、测井解释、岩石薄片与镜质体反射率、全岩/黏土X线衍射等方法,分析储层特征,根据沉积作用、成岩作用等探讨流二段、流三段储层非均质性主控因素.结果表明,沉积相带及分选性差异是流三段储层非均质性主控因素,较远源区分选性好的水下分流河道发育有利储层;沉积相带及压实作用是流二段储层非均质性主控因素,北部弱压实区为最有利储层,其次为中部的中等压实区,第三为南部的近强压实区.该结果为乌石凹陷流沙港组整体评价与目标优选提供地质依据.

关键词(KeyWords)：储层非均质性;沉积作用;成岩作用;有利储层;乌石凹陷;流沙港组
