The Application of Dating Shallow Groundwater with Sulfur Hexafluoride (SF₆) in Groundwater Vulnerability Assessment in the Core Area of Daqing Oilfield

Abstract:

Dating and tracing young groundwater with sulfur hexafluoride (SF₆) is a new technology developed several years ago. To study the origin, evolution of shallow groundwater in the core area of Daqing Oilfield, and to analysis the relationship between groundwater migration and groundwater vulnerability, the age of shallow groundwater was calculated using SF₆ dating technology. The result shows that, (1) the SF₆ age can indicate groundwater flow conditions of research area, (2) the general trend of SF₆ age is getting old from the north to the south, (3) the SF₆ age of most areas is good consistent to the groundwater vulnerability.
