烟台市地热资源勘查开发利用现状与远景规划

Present Condition and Long-term Planning of Geothermal Resources Exploitation Yantai City

烟台市地热资源主要分布在北纬37°15′以北的花岗岩地区断裂构造带交会部位，多属断裂构造控制的对流型中低温地热田。烟台市现有地热井24口，均属热水型，其温度范围26～87℃，主要用于洗浴、养殖、采暖、娱乐4个方面。通过对地热资源的勘查开发利用现状和开发中存在的问题分析研究，进而提出地热资源勘查开发利用的远景规划。

Geothermal resources in Yantai city are mainly distributed in intersection part of tectonic belt faults in granite areas in north latitude 37° 15 ′. It belongs to low--temperature geothermal field controlled by fault belts. There are 24 geothermal wells in Yantai city. They all belongs to hot water types with the temperature range from 26℃ to 87 ℃. These geothermal resources are mainly used in 4 aspects as bathing, farming, heating and entertainment. Although management countermeasures have been carried out to strengthen geothermal resources utilization, there are still many problems. Through study on present condition, utilization and exploitation of geothermal resources, countermeasures for geothermal resources exploitation and utilization, and a long--term exploitation plan are put forword in this paper.
