Hydrological logging

There are many kinds of geophysical logging methods. Commonly used hydrological logging methods mainly include natural electric field method, resistivity method, natural gamma method, and acoustic wave method.

Both the natural electric field method and the resistivity method belong to electrical logging, which is commonly known as electrical logging. The drilling rig is mainly used to determine the location and thickness of the aquifer, divide the interface between salty and fresh water, and estimate the The water quality and quantity after the well is completed. When exploiting deep fresh water, electrical logging can provide a reliable technical basis for the design of the well pipe structure and the determination of the sealing depth of the salt water layer.
