摘要
干热岩资源作为地热资源的重要赋存形式,属于新兴地热能源,因其能量巨大、分布广泛、清洁低碳、热能稳定持续的优点被看作是极具开发前景的战略性接替能源。在“双碳”背景下,开发干热岩地热能在调整能源结构、完善清洁能源供给体系和推进生态文明建设方面具有重大现实及战略意义,干热岩资源勘查是其开发利用深度与广度的前提和基础。在论述我国干热岩资源分布概况和现有开展的勘探工程成果的基础上,阐述了目前常用于干热岩资源勘查的遥感、地球物理、地球化学技术的机理、研究进展及优缺点,单一勘查技术均有一定的局限性和适用性,提出了今后应从加强地热勘查技术综合应用、新勘查技术开发研究、高精度探测设备研制等方面开展攻关研究,从而提升干热岩资源勘查与评价程度和精度,以期对我国未来干热岩资源勘查及开发利用提供技术参考和借鉴,为促进我国节能减排、能源结构调整以及缓解能源资源压力提供支撑。
As an important occurrence form of geothermal resources,dry-hot rock resources belong to new geothermal energy.Because of its huge energy,wide distribution,clean and low carbon,stable and sustainable thermal energy,it is regarded as a strategic alternative energy with great development prospects.Under carbon peaking and carbon neutrality background,developing dry-hot rock geothermal energy has great practical and strategic significance in adjusting energy structure,improving clean energy supply system and promoting ecological civilization construction.The exploration of dry-hot rock resources is the premise and foundation of its development and utilization of depth and breadth.Based on discussing the distribution of dry-hot rock resources in China and the achievements of existing exploration projects,this paper expounds the mechanism,research progress,advantages and disadvantages of remote sensing,geophysics and geochemistry technologies commonly used in the exploration of dry-hot rock resources.As a single exploration technology has certain limitations and applicability,this study puts forward that research should be carried out in integrated application of geothermal exploration technology,new exploration technology development and high precision device development,to improve the degree and precision of exploration and evaluation of dry-hot rock resources,to provide technical reference for future exploration,development and utilization of dry-hot rock resources in China,and providing support for promoting China s energy conservation and emission reduction,energy structure adjustment,and relieving the pressure of energy resources.
