摘　　要：运用储层地质学理论,利用钻井、岩心分析,测井解释资料,从岩石学特点、孔隙类型、结构特征、隔夹层分布以及储层非均质性等方面,对核三段Ⅶ油组储层展布和储层物性的空间变化规律进行分析、描述,指出沉积微相、隔夹层分布对储层非均质性起控制作用。结果表明,研究区储层为中孔、中-高渗,细喉-较细喉,不均匀类型强非均质储层,不同沉积相带其储层物性各不相同。充分认识核三段Ⅶ油组储层特征为该区进一步滚动开发奠定了地质基础。Reservoir distribution and positional changing law of petrophysical property are analyzed and described from as- pects of lithology,pore type,structure feature,interbed dis- tribution and reservoir anisotropy,by applying reservoir ge- ology and using drilling,core analysis and log interpretation knowledge.It yields that both sedimentary facies and inter- bed distribution control reservoir anisotropy.Effects show that,reservoir in study area is featured of medium pore,me- dium to high permeability,thin to thinner throat and heavy anisotropy;petrophysical property differ from every sedi- mentary facies.To fully understand features of Eh3Ⅶres- ervoir provides geological evidence to further development of the area.
