摘要： 在分析岩石薄片、铸体薄片和毛管压力参数等化验资料的基础上,结合测井解释成果,从岩石类型、储集层物性、孔隙结构及非均质性等方面对沈家铺油田孔一段枣V油组进行了综合评价。研究发现,孔一段枣V油组岩石类型主要为岩屑长石砂岩,其次为长石砂岩、岩屑长石杂砂岩;孔一段枣V油组为中孔、中渗储集层,其物性主要受沉积微相、粒度中值及泥质含量等因素影响。研究认为,孔一段枣V油组具有较强的平面、层间、层内非均质性,并可划分为四类,以II类和川类储集层为主,II类储集层最为发育。

Abstract: A comprehensive evaluation of Zao-V oil measure of Upper Kongdian formation in Shengjiapu oilfeld in aspects of rock type, petrophysical property, pore structure and heterogeneity is made, based on analyses of core thin-section, cast thin-section and capillary pressure parameters, together with well log interpretations. Study shows that the rock type of Zao-V oil measure is mainly lithic feldspartharenites, secondly feldsparthic sandstone and lithic feldsparthic greywacke, with medium porosity and permeability; the petro-physical property is controlled by sedimentary microfacies, median size and shale content, etc. It is concluded that Zao-V oil measure is of distinct plane, inter-layer and inner-layer heterogeneities, and could be classified into four types of reservoirs, of which type-II and type-III are the major reservoirs, and type-II reservoir is the best in quality.
