摘要

construction and operation of oil and gas wells, particularly, control of tightness of annulus in development and prospecting and other wells. SUBSTANCE: method is based on gamma logging, injection into well of soft marked tool consisting of three sections: cleaning, indicating and separating, and determination of intervals of disturbed tightness of casing string by increasing of gamma activity intensity.
