我国地热资源非常丰富,开采和利用地下热能有着广阔的前景。但是,当前在试验、开采过高温的(大于100℃)地下热水时,遇到了由于过高温热水所产生的高压蒸气倒灌储气筒致使空压机难于保持长期运转的问题。为解决这一问题并寻找新的试验、开采方法,笔者在福建漳州某地温泉钻井开采试验过程中,采用了温泉人工自喷试验装置并获成功。这不仅解决了开采设备问题,同时也节省了大量材力消耗,为今后过高温地下热水的开采找到了一条新的途径。
China is rich in geothermal resources and has broad prospects for exploiting and utilizing underground thermal energy. However, when underground hot water having a high temperature (greater than 100° C.) has been tested and mined, a problem has arisen in that the air compressor is difficult to maintain for a long period of time due to the high-pressure steam inverting the air reservoir generated by the excessively high-temperature hot water. In order to solve this problem and find new tests and mining methods, the author adopted a hot spring artificial spray test device and succeeded in the hot spring drilling and extraction test in a place in Zhangzhou, Fujian. This not only solves the problem of mining equipment, but also saves a lot of material consumption, and has found a new way for the exploitation of high-temperature underground hot water in the future.
