Abstract:
    The invention discloses a geophysical exploration device and the method which combines the nuclear magnetic resonance and the transient electromagnetism. First to select the coupled device in the transient electromagnetism mode, and it lays the emission loop and the receiving loop to detect every measuring point in the detecting section and treat the transient electromagnetism data to find the low electrical resistivity point; then it changes to the nuclear magnetic resonance mode and lays the emission loop using the demarcated abnormal detecting point as the center, so it compares the detected data or the figure with the resistivity detected by the transient electromagnetism to judge the true or false of the detected resistivity. The invention can decrease the device cost and improve the detecting efficient and the precision.
