摘　　要：利用岩石薄片鉴定、岩心分析及测录井资料,研究了腰英台油田储层岩石学特征和物性特征,对影响储层物性的因素进行了分析。结果表明:腰英台油田青山口组储层岩石类型主要为长石砂岩,岩性以细砂岩和粉砂岩为主,分选中等、磨圆中等-较差,砂岩成分成熟度较低、结构成熟度中等-较低。储层的孔隙结构较复杂,非均质程度较高,孔隙的最大连通孔喉普遍偏小,主要孔隙类型有粒间孔隙、溶蚀孔隙、微孔隙,储层为低孔特低渗及特低孔超低渗储层。影响储层物性的因素主要有沉积微相、碎屑成分和结构以及成岩作用等。Based on rock slices identification,core analysis and logging data,the study on petrologic characteristics and reservoir properties of Yaoyingtai oilfield,and the influencing factors analysis of reservoir properties have been carried out.The results showed that the reservoirs of Qingshankou formation are mainly of feldspathic sandstone,with lithology of fine sandstone and siltstone,moderate sorted,mid-poor rounded,lower sandstone compositional maturity,and mid-low structure maturity.The reservoir pore structure is complex,the heterogeneity degree is high and the largest connected pore throat is generally small.The main pores include intergranular pores,dissolution pores and micropores.The reservoirs belong to low-porosity ultra-low permeability and ultra-low-porosity super-low-permeability.The main influencing factors are mainly sedimentary microfacies,debris composition and structure,and diagenesis.
