The situation and progress of electromagnetic well logging

LIU Si-xin,TONG Wen-qi(Department of Geophysics, Jilin University, Changchun 130026, China)  
As an important tool of geophysical well logging, electromagnetic well logging is able to measure the conductivity and dielectric constant of surround formation, which are very important to evaluate the oil saturation. Former Soviet Union initiated this research very early and achieved many results. But the current commercial products are all from United States and other countries. Our country started this research early, but there are no commercial products. In the future, we should overcome some theoretical and technical difficulties, and put out our electromagnetic tool and interpretation technique.
