秦皇岛地区地热资源开发利用中出现的问题与对策

秦皇岛地区地热资源丰富,地下热水被广泛开发利用。地下热水开发利用过程中出现的环境问题,表现在高矿化热水上涌引起的土壤盐碱化和局部地区水温逐年下降。为解决这些环境问题,必须加强管理,制订合理的地下水开采方案;改进落后的成井工艺,由专业队伍施工水井,采取必要措施切断冷热水的水力联系;在高矿化热水井附近打回灌井,阻止土壤盐碱化。

Problems and Solutions to the Exploitation of Geothermal Resources in Qinhuangdao District

Geothermal resources in Qinhuangdao area is rich, and geothermal water is widely developed and used. Together with the development and utilization of geothermal water, there are some environmental problems such as soil salinity caused by the upwelling of high mineralized hot water and water temperature dropping year by year in certain area. To solve these problems, we should strengthen the management and make reasonable mining plans of geothermal water development, improve the craft of drilling wells and get them done b）; professional contingents, take effective measures to cut down the water power connection, drill recharge wells near the high mineralized ones to prevent the soil from salinity.
