摘　　要：松辽盆地资源与环境深部钻探工程是针对白垩纪古气候与古环境研究、地球深部资源调查以及基础地质研究等一系列科学问题而实施的科学钻探。松科二井是松辽盆地科学钻探工程的主体钻孔,设计的测井项目齐全,采集了丰富、连续、原位的地球物理测井资料。本文主要利用该孔的测井资料研究深部火石岭组地层岩石物理学特征;结合实验室岩心核磁共振测试结果,分析不同岩性储层的孔隙结构特征。研究表明,火石岭组地层主要发育安山岩、凝灰岩、复成分砾岩和凝灰质泥岩,其中火成岩岩相以爆发相和喷溢相为主,安山岩和复成分砾岩表现为高电阻率、低声波时差特征,凝灰岩为低电阻率、高声波时差特征,凝灰质泥岩电阻率最低;储层整体上具有低孔低渗的特点,但凝灰岩储层小孔和中孔发育,物性相对较好,是较为有利的储层。研究结果为进一步评价松辽盆地深部油气资源和地层结构提供了有力支持。The Continental Scientific Drilling Project in the Songliao Basin was aimed at solving a series of scientific problems involved in Cretaceous paleoclimate and paleoenvironmental research,the development of deep exploration techniques,and the earth's deep resource survey.As the main borehole of the scientific drilling project of Songliao Basin,SK-2 has collected continuous and in-situ geophysical log data.In this paper,geophysical log data were used to reveal the range of petrophysical parameters of rocks in Huoshiling Formation.Combined with laboratory core NMR test analysis,the authors studied the pore structure characteristics of different igneous reservoirs.The results show that the Huoshiling Formation mainly consists of andesite,tuff,complex conglomerate and tuff mudstone.The igneous facies are dominated by the explosive facies and the effusion facies.The andesite and complex conglomerate are characterized by high resistivity and low acoustic wave time difference.The characteristics of the tuff are low resistivity and high acoustic time difference,and the tuff mudstone has the lowest resistivity.The reservoir has the characteristics of low porosity and low permeability,but the tuff reservoir has developed small and medium pores and has relatively good physical properties,and hence it is a favorable reservoir.The research results provide strong support for further evaluation of deep oil and gas resources and stratigraphic structure in the Songliao Basin.
