摘　　要：氦气作为重要的稀有战略资源越来越受到关注和重视。东北地区氦气资源调查研究程度较低,资源状况不清,富集规律不明。为了认识东北地区氦气资源前景,本文通过对东北地区主要盆地氦气资源调查研究进展与成果进行系统的梳理、分析,结合对松辽、铁法等盆地天然气田含氦情况的调查研究,总结了东北地区氦气富集成藏地质条件。研究认为,东北地区氦气资源主要分布在松辽盆地、海拉尔盆地、辽河盆地、铁法盆地等重点盆地,氦气载体类型主要有烃类、二氧化碳和地层水等,氦气成因类型为壳-幔混合型;东北地区广泛发育的印支期和燕山期花岗岩提供了丰富的氦气来源,深大断裂的发育为氦气的运移聚集提供了必要的通道,良好的保存条件有利于氦气的富集与成藏。As an important and rare strategic resource,helium has attracted more and more attention.Helium resources are abundant in Northeast China,but the degree of investigation is low,the resource status is unclear,and the enrichment is unknown.Based on the systematical analysis of the existing progress and achievements of helium resources in the main basins of Northeast China,combined with the investigation and research of helium content in natural gas fields in Songliao and Tiefa basin,this paper summarizes the geological conditions of heli-um accumulation in Northeast China and analyzes the prospects of helium resources.It is considered that the he-lium resources in Northeast China are mainly distributed in Songliao basin,Hailaer basin,Liaohe basin and Tiefa basin.The main types of helium carrier gas are hydrocarbons,carbon dioxide and water-soluble gas.The main genetic type of helium resources is crust-mantle mixed type,which is dominated by crust source.The widely developed Indosinian and Yanshanian granites in Northeast China provide abundant helium sources,and the development of deep faults provides the necessary channels for the migration and accumulation of helium.The good preservation conditions are conducive to the enrichment and accumulation of helium,and the prospect of helium exploration in Northeast China is promising.
