高青县南部地区地热资源评价

高青县南部地区的热储层主要为新近系馆陶组和古近系东营组。通过野外勘察和室内分析结果，选取合理的计算参数，建立了热储概念模型。在此基础上，分别利用热储法、回收率法对研究区内的地热资源量和可利用地热资源量进行计算评价，同时利用体积法、最大降深法对地下热水的储存量和允许开采量进行了计算评价。结果显示，研究区地热资源量总量为2.5161×1018J，折合标准煤8.587×107t；回收率采用25%，计算得可利用地热资源量为6.290×1017J,折合标准煤2.147×107t；地下热水储存量为6.542×109m3，其中允许开采量为3.833×106m3/a（开采年限为100a）。 The geothermal reservoir in the southern area of Gaoqing County consists mainly of two formations: Neogene Guantao Formation and Palaeogene Dongying Formation. According to the field observation and laboratory analyses，reasonable parameters were selected to develop the geothermal reservoir concept model. On the basis, the heat reservoir method and recovery rate method were used to calculate and evaluate the total and available geothermal resources in the study area, respectively, and the volume method and maximum drawdown method were used to evaluate the storage capacity and allowable withdrawal of underground hot water resources. The results showed that the total geothermal resources quantity is 2.5161 x 1018 J, equal to 8.587 x 107 t of standard coal, and the available geothermal resources is 6.290×1017J, equal to 2.147×107t of standard coal (recovery rate is 25%). Also, the underground hot water storage capacity is 6.542 x 109 m3, and the allowable withdrawal is 3.833 x 106 m3/a based on a production life of 100 years. 国家重点基础研究计划项目（973项目）（2010CB428805）；国家自然科学基金项目(41172212)
