地热资源就是一种来自地球内部的能量资源,是世界上最古老的能源之一。据测算,地球内部的总热能量约为全煤炭储量的1.7亿倍。每年从地球内部经地表散失的热量,相当于1000亿桶石油燃烧产生的热量。地球本身像一个大锅炉,深部蕴藏着巨大的热能。在地质因素的控制下,这些热能会以热蒸气、热水、干热岩等形式向地壳的某一范围聚集,如果达到可开发利用的条件,便成了具有开发意义的地热资源。地
Geothermal resources is a source of energy from within the Earth and is one of the oldest sources of energy in the world. It is estimated that the total heat energy inside the Earth is about 170 million times the total coal reserves. The heat lost from the Earth’s interior by surface every year is equivalent to the heat generated by the combustion of 100 billion barrels of oil. The Earth itself is like a big boiler, deep in the huge heat. Under the control of geological factors, these heat energy will gather in a certain range of the crust in the form of hot steam, hot water, hot-dry rock, etc., and will become exploratory geothermal resources if the exploitable conditions are met.
