Origin and Key Enrichment Factors of Helium Resource in the ...

氦气在天然气中富集的主要原因包括以下几个方面:

  1. 地质条件:氦气主要通过铀(U)和钍(Th)的放射性衰变产生,这些元素在古老的花岗岩等基底岩石中丰富24。放射性衰变产生的α粒子(氦核)在岩石中积累,随后溶解于地下水中12

  2. 构造活动:地质构造运动,如喜马拉雅运动,导致基底岩石的抬升和断裂,形成了通道使得富含氦的地下水能够上升并与天然气混合13

  3. 运输和积聚:氦气需要通过其他流体(如地下水或其他气体)运输,以便在天然气储层中富集12。在天然气储层中,氦气与其他气体(如氮气)一起被困住,形成了富含氦的天然气24

  4. 封闭条件:天然气储层需要有良好的封闭条件(如不透水的盖层),才能防止氦气泄漏,确保其在储层中积聚24
