Abstract：Logging Technology has been being widely used in the fields of coal field, natural gas, freshwater resources, petroleum and solid minerals, which has gained lots of achievements and experience, but it is seldom used in the exploration of deep brine resources. By studying the logging results of many projects such as "Exploration of Mahai Deep Brine Potassium Deposit in Lenghu Town of Qinghai Province", the paper summarizes the characteristics of parameters including laterolog-3 resistivity,natural gamma-ray, sonic differential time and spontaneous potential in Cenozoic strata, and finds the common logging method being an indispensable guide to the exploration for salt lake resources, particularly for deep brine resources. The relation between characteristics of logging curves and single well sequence is found through statistical analysis of large amounts of logging data in the basin. Then the quantitative recognition is used to analyze and verify the parameter range and curve characteristics of natural gamma-ray and sonic differential time, and the logging interpretation method suitable for deep brine exploration in Qaidam Basin is summarized finally.
