Abstract:The salt diffusion method hydraulic logging is a kind of geophysical exploration method. It has gained good effect in deep survey in Jiaojia gold deposit. Basic principle,work steps of salt diffusion method hydrological logging are introduced in this paper, salt diffusion method hydrological logging resistivity anomalies is studied as well. According to the change of liquid electric resistivity, the water table, water location, direction and supply of fresh water or salt water are determined.
