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Ⅲ类储集层为主,Ⅱ类储集层最为发育。
Based on the analysis of laboratory test data such as rock slice, casting thin slice and capillary pressure parameter, combined with well logging interpretation results, the first section of Kongji Section of Shenjiabu Oilfield is analyzed from the aspects of rock type, reservoir physical properties, pore structure and heterogeneity Jujube Ⅴ oil group conducted a comprehensive evaluation. The study found that the rocks of Jurajiao Formation in Kong-1 section are mainly feldspathic feldspathic sandstones, followed by feldspar and feldspathic feldspathic miscellaneous sandstones, and the pores of Jura-Ⅴ section of Kong-1 section are mesopore and intermediate-permeability reservoirs. Their physical properties Mainly affected by sedimentary microfacies, median grain size and shale content and other factors. According to the study, there is a strong plane, inter-layer and intra-layer heterogeneity in the Jujube Ⅴ oil group in the Kong-1 Member, which can be divided into four types, mainly Type II and Type III reservoirs, and Type II reservoirs development.
