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.
