高温岩体圈定的思路与方法探讨

Discussion on the determination methods and strategy for hot dry rocks

高温岩体地热资源开发利用首先要解决的是在目前技术和经济条件下可以开发利用的高温岩体分布地区和赋存深度及规模。提出了高温岩体圈定的基本思路应该是在对高温异常区的岩石类型及分布、断裂构造格架及其活动性、火山活动和岩浆侵入的类型及时代等基础地质研究的基础上,并充分利用地球物理探测技术、遥感技术、地球化学方法,配合少量深钻验证工程来进行。特别强调了在高温岩体地热资源圈定和评价中多种方法和技术的相互配合、相互补充、相互验证。

In the utilization and development of HDR geothermal resources, the first problem is where exists hot dry rocks （HDR） that could be developed on the current technological and economical level. The valid and economical methods of determing HDR should be based upon the detail investigation on the rock types and distribution, fault frameworks and activities, volcano and intrusion types and ages, with the combination of geophysical exploring, geochemistry exploring, remote sensing and deep drill technologies. The integrated combination of various methods should be emphasized in the determination of HDR.
