| On the basis of previous research results, the thesis combined with basic characteristics of sedimentary basin geothermal field, aimed sedimentary basin geothermal field which clastic rock is the main reservoir, that is, geothermal fields with pore-type thermal reservoir, and selected eight parameters such as, underground temperature of geothermal field, geothermal reservoir thickness, porosity, permeability, ground water salinity, groundwater pressure coefficient, single well production and wellhead temperature. Then established calculation model for the relevant parameters, based on above, established the quantitative model of geothermal resources comprehensive evaluation through computer programming.Songliao Basin is a large Mesozoic and Cenozoic sedimentary basin in China, as well as one of land-based geothermal water resources relatively concentrated areas in China. A large number of research information for geothermal resources are provided through years of oil and gas research. According to quantitative evaluation parameters which involved in the evaluation system, carried out integrated research on geothermal resources of Songliao Basin through the aspects such as geothermal field characteristics of Songliao Basin, characteristics of thermal energy storage stratigraphic and sedimentary, thermal reservoir characteristics and characteristics of the geothermal carrier passage system, thus obtained initial understanding on geothermal resources of Songliao Basin. According to the geothermal research on Songliao Basin, selected typical geothermal field of the basin (Lindian geothermal field and Dongfeng geothermal field), adopted the quantitative evaluation system established in the thesis, combined with specifically geothermal geological conditions of each research area, evaluated geothermal resources respectively. The evaluation results provided basis for further development and utilization of geothermal resources in the two geothermal fields.
