【摘要】 本文在整理前人研究成果的基础上,结合沉积盆地型地热田的基本特征,针对以碎屑岩热储层为主的沉积盆地型地热田,即孔隙型热储地热田,选取地热田的地下温度、热储厚度、孔隙度及渗透率、地热水矿化度、地下水压力系数、单井产能和井口温度等八个参数,建立相关参数的计算模型,并在此基础上通过计算机编程,建立了地热资源综合评价的定量模型。松辽盆地是我国中、新生代大型沉积盆地,也是我国陆上地热水资源分布相对集中的地区之一。多年来对其油气的研究过程中,提供了大量可供地热资源研究的相关资料。本文以评价系统中涉及到的定量评价参数为依据,从松辽盆地的地温场特征、热储地层及沉积特征、热储物性特征及地热载体输导体系特征等方面对其地热资源进行了综合研究,从而对盆地的地热资源概况得到了初步了解。根据松辽盆地的地热研究,选取盆地中典型地热田(林甸地热田及东风地热田),应用文中所建立的定量评价系统,并结合各研究区具体地热地质条件,分别进行地热资源的综合评价,评价结果为这两个地热田地热资源的进一步开发利用提供了依据。更多还原

【Abstract】 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.更多还原
