以长岭凹陷葡萄花油层为例，以储层地质学理论为指导，利用岩心分析、测井、录井、分析化验、薄片、扫描电镜、X衍射分析等手段资料，建立姚家组一段基础资料库，确定储层的岩性特征、沉积特征、成岩作用、孔隙结构和物性特征。姚家组一段主要为三角洲前缘相的水下分支河道。岩石类型主要为岩屑质长石砂岩和长石质岩屑砂岩，岩石粒度相对较粗，主要以粉砂、细砂为主。储层孔隙主要以原生孔隙次生溶蚀扩边为主。储层孔隙度主要分布在10%~20%之间，渗透率主要分布在0.01×10-3~20×10-3μm2之间。通过测井与地质及试油资料综合对比研究，确定岩性、物性、含油性、电性下限标准。经过该区域储层68口井442个层测试验证，解释符合率提高10%，使得今后在该类油气层解释评价中具有一定的指导和借鉴意义。

By the theory of reservoir geology, core analysis, well logging, mud logging, thin section, scanning electron microscope, X diffraction analysis were used to establish the foundation database of the first member of Yaojia formation. Then the lithologic characteristics, reservoir sedimentary characteristics, reservoir diagenesis, pore structure and physical characteristics were determined. The results show that the first member of Yaojia formation is mainly subaqueous distributary channel of delta front facies;the rock types are mainly lithic feldspar sandstone and feldspathic lithic sandstone, rock grain size are relatively coarse, mainly composed of silt and fine sand; reservoir porosity is mainly primary pores and secondary dissolution extension;reservoir porosity is mainly distributed between 10%and 20%, permeability is mainly distributed between 0.01×10-3 and 20×10-3μm2. The limit of the lithology, physical property, oiliness, and electrical standards were determined by logging and geological comprehensive comparative study and test data. Interpretation coincidence rate was increased by 10%by 442 layer test validation of 68 Wells in the regional reservoir.
