This paper deals mainly with an electromagnetic coupling correction technique for phase IPmethod (dipole dipole, called dipole for short). Its principle is as follows: the apparent resistivity is regarded approximately as uniform terrestrial resistivity, and the direct calculation method for electromagnetic inductive response of dipole device is employed under the uniform terrestrial condition to figure out electromagnetic inductive response; then the inductive response is subtracted from the observed total response so as to attain the aim of electromagnetic coupling correction.
