天然氢气藏地质环境及找矿方向
Geological environments and prospecting direction of natural hydrogen reservoirs
摘要
Abstract
Natural hydrogen is a kind of clean energy with sustainable potential.Recently,there has been a global surge in the exploration of natural hydrogen.Based on results of global natural hydrogen ex-ploration and researches on the storage characteristics and formation mechanism of the hydrogen reser-voir,this paper synthesizes the geological environments of the reservoir,including continental craton ba-sins,rift basins,and orogenic belts enriched with mafic-ultramafic rock sequences.The natural hydrogen is derived from radiolysis and water-rock interaction.Precambrian basement rocks are the main source rocks.The natural hydrogen reservoir requires a combination of favorable generation,migration,storage,and caprock conditions.Impermeable strata such as mud stone,shale,salt layers,and dense diabase or basalt serve as effective caprocks,while sandstone,limestone,and dolomite are the suitable reservoirs.Soil gas and associated element geochemical measurements are the primary exploration methods.Isotopic data offer critical insights into hydrogen origins.Non-gas and oil craton basins,rift basins,and orogenic belts are the optimal targets for the natural hydrogen prospecting.China possesses diverse tectonic set-tings favorable for natural hydrogen exploration,particularly in over 30 basins within the North China and Yangtze Cratons,where widely distributed iron-bearing formations in the basement serve as critical"hy-drogen source rocks."This paper provides a theoretical framework and practical guidance to advance natu-ral hydrogen exploration in China.关键词
