摘要: 山东平阴县北部近年来发现了赋存于泰山岩群基底变质岩类构造裂隙中的地热资源,分析研究地温场特征、大地热流值及岩石放射性生热条件对于预测、评估研究区地热资源形成潜力具有重要意义。根据研究区井孔测温以及水样、岩石样品的测试数据,系统分析了研究区地温场特征,计算了泰山岩群变质岩地层大地热流值及其岩石放射性生热率,并根据地下水中的SiO2含量计算了研究区硅热流值。结果显示: 研究区上部盖层地温梯度平均值为2.07 ℃/100 m,泰山岩群地温梯度平均值为2.18 ℃/100 m,平面上呈西低东高分布,垂向上随深度增加而增大; 研究区泰山岩群变质岩地层的大地热流值低于中国大陆地区大地热流平均值,具有较低的热流背景; 研究区硅热流值略高于钻孔实测数据,同时泰山岩群放射性生热率较低,属于低产热岩体。综合分析表明地温场分布主要受区域地质构造及地层结构影响,研究区地温分布总体处于正常范围,但在区域上具有相对较低的热流背景,热源方面主要为传导生热,其次为岩石放射性生热。研究成果可为研究区地热地质条件研究以及后续勘查开发工作提供基础数据和科学依据。Abstract: In recent years, geothermal resources were explored in the structural fissures of metamorphic rocks of Taishan Group in the northern Pingyin County of Shandong Province. It is of great significance to analyze and study the characteristics of geothermal field, terrestrial heat flow and radiogenic heat production rate of rocks, for predicting and evaluating the formation potential of geothermal resources. Based on the borehole temperature data and the test data of water and rock samples, the authors systematically analyzed the characteristics of the geothermal field in the study area, and calculated the terrestrial heat flow and the radiogenic heat production rate of the metamorphic rocks of Taishan Group. Besides, the silica heat flow in the study area was calculated based on to the SiO2 content in the groundwater. The research show that average geothermal gradient of the overlying strata in the study area was 2.07 ℃/100 m, and the average geothermal gradient of the metamorphic rocks of Taishan Group was 2.18 ℃/100 m, with the lateral distribution of low in the west and high in the east, and the vertical distribution of increasing with depth. The geothermal heat flow value of the metamorphic rocks of Taishan Group in the study area is lower than the average geothermal heat flow in China mainland, indicating a low heat flow background. The silicon heat flow value in the study area is slightly higher than the measured borehole data. The radiogenic heat production rate of Taishan Group is low, and Taishan Group belongs to low heat-producing rock mass. Comprehensive analysis shows that the geothermal field distribution is mainly affected by regional geological structures and stratigraphic structures. The geothermal distribution is generally within the normal range, but it has a relatively low heat flow background in the study area. The heat source is mainly conductive heat generation, followed by rock radioactive heat generation. The research results could provide some basic data and scientific basis for future research on geothermal geological conditions in the study area and subsequent exploration and development work.
