摘　　要：地热能作为一种清洁低碳、可循环利用的稳定能源,其开发利用对于推动温室气体减排,实现碳中和、碳达峰目标具有重要意义。目前,中国资源开发利用主要集中在浅层地温能方面,中深层地热能勘探受储层埋深大、勘查手段单一等影响勘查难度较大,为提高地热勘查效率,需引入成本低、环境破坏性小、施工效率高、探测深度大的地球物理技术。本文介绍了近年来中深层地热资源调查采用的重、磁、电、震等多种地球物理方法的基本原理与应用概况,并对不同地球物理方法的特点和适用条件进行了对比分析,为不同的地质背景条件与地热勘探阶段物探方法的选择提供借鉴经验。Geothermal energy as a clean,low-carbon,and renewable stable energy source,plays an important role in promoting the reduction of greenhouse gas emissions and achieving carbon neutrality and peak targets.Cur⁃rently,the development and utilization of geothermal resources in China mainly focus on shallow geothermal energy.The exploration of medium-deep geothermal energy faces challenges such as large reservoir burial depth and limited exploration methods,which result in difficulties in exploration.In order to improve the efficiency of geothermal exploration,it is necessary to introduce cost-effective,environmentally friendly,highly efficient,and deep-detecting geophysical technologies.This article introduces the basic principles and application overview of various geophysical methods such as gravity,magnetic,electrical,seismic used in the investigation of medium-deep geothermal resources in recent years.It also provides a comparative analysis of the characteristics and applicable conditions of different geophysical methods to offer reference experience for selecting appropriate geological background conditions and prospecting stages for different geophysical methods.
