Abstract

In order to study the influencing factors of water and salt enrichment, this paper mainly analyzed the moving rules of water and salt and water chemical variation characteristics under the control of groundwater flow. Combined with the ancient climate fluctuations, it reproduces the evolution process of water and salt migration in geologic history. The results show that there only develop the local water flow system and regional water flow system in the present condition, and the proportion of local water system circulation reaches 82.25%. They also indicate that the water and salt migration and enrichment process are obviously affected by the flow system. Besides, water-soluble fractions tend to concentrate continuously. The simulation results also show that the coupling relationship between water and salt transport and groundwater flow is mainly reflected in the change of fluid density. When the concentration of water-soluble components is largely different, the effect of fluid density on water flow cannot be neglected.
