地热资源是一种宝贵的可再生能源.地热资源中的热能、地热流体等是一种具有较高社会利用价值的热能.经过地质勘探,地热资源中可利用的主要是自然形成的温泉和浅层的地热能.分析了煤田地质单位在地热资源勘查中钻井方法薄弱、钻井效率低、施工周期长的现状,并预测了未来的发展趋势.通过概述中国地热资源的分布情况,分析和总结了地热资源复杂的地质特征和形成原因,列举了各种地质情况对钻井施工的主要影响,并给出了相关的技术措施.
Exploration Technology of Geothermal Resources in Coalfield Geological Units
Geothermal resources are a valuable renewable energy.The thermal energy and geothermal fluid in geothermal resources are a kind of thermal energy with high social utilization value.After geological exploration,the natural hot springs and shallow geothermal energy in geothermal ersources are mainly available.This paper analyzed the current situation of weak drilling methods,low drilling efficiency and long construction period in geothermal resource exploration by coalfield geological units,and predicted the future development trend.And it summarized the distribution of geothermal resources in China,analyzed and summarized its complex geological characteristics and causes,listed the main impacts of various geological conditions on drilling construction,and gave relevant technical measures.
