RADIOACTIVITY OIL-WATER WELL LOGGING UTILIZING NEUTRON SOURCE

摘要

Device for radioactivity logging for radiation which stemmed from a borehole through an examination by neutron for the logging of stratum. Radiation monitor is composed of the propertional gamma radiation which have the multi-channel pulse height analyser connected to a radiation monitor for the generating signal. 1st limits of energy were applicable to gamma radiation 1.3 MEV-3.0 MEV and 2nd were applicable to 40MEV or the level of the minimum neutron captured gamma radiation to be contained.
