device for nuclear magnetic log

摘要

device for nuclear magnetic log containing a current source polarization, the polarization with the u043eu0442u0432u043eu0434u0430u043cu0438 coil which are connected through contacts with key the source of the current polarization and the entrance of the measuring amplifier, differing, however, that, in order to improve the reliability and precision of the measurement, it introduced with united between a current pulse generator and a coila coil u0441u043eu043eu0441u043du043e polarization, and switch, and which are connected with a power source and the entrance of the polarization current pulse generator.
