西张地区中低温地热资源利用前景分析

西张地区为北亚热带沿海湿润气候区域,季风盛行,夏季需要制冷.冬季需要供暖.因此,对于浅层地热能的开发利用具有得天独厚的自然条件.通过地温测量的调查方法,观测和研究地球内部各种热源形成的地热场随时间和空间的分布规律,进一步推断西张家地区地质构造,确定地热钻井位置,再通过可控源大地音频电磁测深方法,推断深部地层结构、热储埋深及断裂位置,确定地热钻井位置,最后进行地热钻井验证和单井地热资源评价.研究结果表明;本区地热资源具有很大的利用前景.

Prospect Analysis of Medium Low Temperature Geothermal Resource of Xizhang Area

The area is in the north subtropical coastal moist area , monsoon climate prevails , refrigeration is necessary in summer , and heating is necessary in winter.Therefore , for this area the development and utilization of shallow geothermal energy has advantageous natural conditions.In this article , through the survey methods of temperature measurement observations , we studied the distribution regularity of geothermal fields formed by various heat sources with time and space.And the geological structure of Xizhang area was further inferred , the geothermal drilling locations were determined.And then the deep strata structure , heat sources buried depth and fracture reservoir position were inferred by the controlled source earth audio electromagnetic sounding method.Finally , geothermal drilling authentication and single well geothermal resource evaluation were carried out.The results of the study indicate that the use of geothermal resources has a great future.
