摘　　要：靖边油田天赐湾区三叠系延长组长4+5油层组作为近些年新发现的油藏,为延长油田的稳产增储和国家能源安全做出了重要贡献。天赐湾区长4+5油层组的储层特征及其分布规律仍然认识不清,需要进一步深入研究。利用岩心化验分析数据,系统研究了储层岩石学、物性与孔喉结构特征,对储层进行了综合评价与分类,为油田下一步勘探开发提供了重要依据。The Chang4+5 reservoir of Tianciwan block is a newly discovered reservoir in recent years,and has made an important contribution to the stable production of Yanchang oilfield and national energy security.The reservoir characteristics and distribution law of Chang4+5 reservoir of Tianciwan block are still unclear and need to be further studied.In this paper,using the core test and analysis data,the characteristics of reservoir petrology,physical properties and pore throat structure were systematically studied,and the reservoir was comprehensively evaluated and classified,which could provide an important basis for the next exploration and development of the oilfield.
