摘要:

干热岩(Hot Dry Rock,HDR)地热资源又称作增强型地热资源(Enhanced Geothermal Resources,EGS),是地热资源的重要组成部分.目前国际上非常重视干热岩地热的勘探开发,干热岩地热资源在今后清洁能源开发中潜力巨大,研究干热岩对于环境保护、能源利用、国家发展都具有重大的意义.本文回顾了国内外干热岩勘探开发现状;简要分析干热岩岩体地球物理特征;结合我国干热岩勘探实例总结了常用的干热岩勘探方法及存在的问题.在干热岩勘探开发过程中,经济有效地选择合适的干热岩靶区是关键.通过对我国干热岩靶区勘探方向及方法选择的探讨,概括了我国目前圈定干热岩靶区的探测方法,说明了地球物理勘探方法在干热岩开发环节中的重要性.希望通过本文的概述,读者能够对地球物理方法勘探干热岩有初步的认识,以期本文对干热岩地热资源开发勘探有一定指导作用.

Abstract:

Hot Dry Rock (HDR)geothermal resource, also known as Enhanced Geothermal Resources(EGS), is an important part of geothermal resources. At present, the international community pay great attention to the exploration and development of HDR geothermal resource, and which is a potential clean energy in future energy development. Exploring and researching HDR is of great significance for environmental protection,energy utilization,and national development. In this paper, we review the present situation of HDR exploration and development in domestic and abroad and analysis the geophysical characteristics of HDR. Combining with some exploration examples of HDR in China, we summarize the common exploration methods and existed problems. The cost-effectively selection of suitable target areas is crucial to the successful exploration and development of HDR. By discussing with the exploration direction and method selection of target area of HDR in China, we expound the steps of the detection method for HDR and which reflects the importance of geophysical exploration methods in the development of HDR. Base on above analysis, we hope readers can have a preliminary understanding of the development of HDR exploration and development and expect that it will be a guiding role in the development and exploration of HDR geothermal resources.
