PROCESS OF CALIBRATION OF EQUIPMENT FOR INDUCTION LOGGING

摘要

FIELD: geophysical method of examination of holes. SUBSTANCE: process of calibration of equipment for induction logging includes supply of signals of tests to input of measurement transducer which conductance is less than sensitivity zone of device or is a little bigger. Start of range of measurement Co of equipment is found by formula $$$, where $$$ is signal "zero in air"; $$$ signal of test equivalent to the biggest conductance of rocks within examined section $$$; $$$ is nominal of test from which first deviation of pointer of device occurred; $$$ is value of its output signal. Value Co is imparted to zero of scale dial recorded along section of hole. EFFECT: improved reliability of process.
