摘　　要：对采自GR1井钻孔的10块岩心样品开展了热导率、生热率、密度及孔隙度等物性参数测试,揭示其空间展布特征、相互关系及主控因素,建立了松辽盆地中部研究区新生界地层平均热导率和生热率,估算盆地沉积物的放射性生热贡献约占地表热流的33%。研究表明,埋深3900~4000 m段砂岩、砾岩具备良好的传热效果,可作为水平段换热目的层,这些实测的岩石热物性参数为松嫩沉积盆地的盆地模拟与地热相关研究提供了坚实的基础数据。The thermal conductivity,thermal generation rate,density and porosity of 10 core samples taken from GR1 borehole were tested.Their spatial distribution characteristics,interrelationships and main controlling factors were revealed.The average thermal conductivity and thermal generation rate of Cenozoic strata in the central Songliao Basin were established.It is estimated that the radioactive heat generation contribution of the basin sediments accounts for about 33%of the surface heat flow.The study shows that the sandstone and conglomerate in the 3900~4000 m buried depth have good heat transfer effect and can be used as the target layer of horizontal heat transfer.These measured rock thermal physical parameters provide solid basic data for basin simulation and geothermal related research in Songnen sedimentary Basin.
