江苏地热资源类型及开发利用前景

按照发育深度将江苏地热资源分为地表出露的温泉、深度小于200 m的浅层地温能、深度为200～3 000 m的中浅成地热水和 3 500～5 000 m的深成干热岩四大类。江苏地热资源类型较多，成因复杂，各类型地热资源皆具有各自的分布规律与发育特点。其中，浅层地温能、中浅成地热水资源和深成干热岩型地热资源的开发利用前景广阔。

Geoheat resource types and development prospect in Jiangsu Province

Based on the development depth of geoheat resource, the authors classified the geoheat resource into four types: surface exposed spring, shallow geoheat of less than 200 m, medium shallow geothermal water as deep as 200 m to 3 000 m, plutonic dry rock as deep as 3 500 m to 5 000 m. Jiangsu was characteristic of varied types of geoheat resource, complicated origin, unique distribution rules and developing properties. In which, shallow geoheat, medium shallow geothermal water and plutonic dry rock were of potential prospect in exploitation.
