Progress and prospective analysis of natural hydrogen investigation research in Shangyi-Zhangbei area
摘要
Abstract
Under the background of the global energy transition,natural hydrogen has emerged as a research hots-pot in the field of new energy,and many countries have successively launched investigations into natural hydro-gen.On the basis of previous research findings,Zhangbei Basin,with the presence of H2 escape,is designated as a key area for natural hydrogen research.Then,geological,soil gas geochemical,gravity,and magnetotelluric sounding investigations were carried out in Shangyi-Zhangbei area.The results reveal that soil H2 anomaly in Shangyi-Zhangbei area exhibits a ring-shaped distribution pattern with high values in the periphery and low val-ues in the center around Hujiawa-Majugou.H2 concentration in some sampling points exceeds 5,000×10-6.Hydrogen isotope analysis(δD values ranging from-567‰ to-461‰)indicates that H2 is predominantly of mantle-derived origin.Twelve hidden faults and 3 sedimentary depressions have been identified according to gravity and magnetotelluric sounding results,and the basement depth and tectonic framework of the basin have been interpreted.It is considered that faults are favorable channels connecting deep hydrogen sources.The sedi-mentary assemblages of the Cretaceous and the Paleogene-Neogene have the potential for gas storage.Mudstones and dense massive basalt flows play the role of trap caprocks.The sedimentary sag areas with less H2 escape and covered by basalt flows were delimited as favorable areas for further exploration of natural hydrogen,after compre-hensive analysis,with an area of approximately 590 km2.This study could provide basis for further exploration of natural hydrogen in Shangyi-Zhangbei area.关键词
