| Abstract:On the basis of studying geological structural setting and hydrochemical data, the basic characteristics of chemical components of Upper Triassic gas field water were summarized, a series of graphs for hydrochemical field of gas field water were drawn, and the distribution regularity of the chemical field was revealed. The positive and oblique vertical hydrochemical zones are delineated. This research has great theoretical significance in the study of the vadose field in gas field water and the origin of groundwater. |
