摘要：
A group of inventions related to geophysical well logging, in particular to magnetic imaging defectoscopy of well casings including magnetized ones, that can be used to identify and classify defects in production and intermediate casing and tubing strings in oil and gas wells. An electromagnetic multi-sensor defectoscope for surveying casing pipes containing a source of the electromagnetic field in the form of a central exciter coil designed to transmit current pulses from a current pulse generator, a system of measuring elements placed on bow springs to be forced against the inner surface of a casing pipe, and a unit for signal recording, control and data processing connected to the system of measuring elements through communication lines. A method of multi-sensor electromagnetic defectoscopy for surveying casing pipes.
