In an induction-logging measuring method for geophysical borehole measurements, a measuring device which contains in a probe (1, 2) at least two transmitting/receiving units (T, R1 to R4) for induction measurements is guided through a borehole in order in each case to obtain separate electrical signals. A cable (3) holds the probe (1, 2) in the borehole and serves to transmit the separate electrical signals to the surface of the earth. The separate electrical signals are stored at the surface of the earth in a memory unit (23), and can be combined in any desired fashion in order to generate one or more screen displays which represent, as a function of borehole depth, the electrical properties of the earth formation in the region of the borehole. <IMAGE> |
