Abstract

СПОСОБ НЕЙТРОННОГО AJCTIiBA- ПИОНИОГО KAPOTA;|U\, включающий непрерывные измерени  фона и общего эф- .фекта от наведенной и естественной радноакт'-ганости п-ри перемещении сква- жинного прибора с посто нной непре- рьшно регистрируемой скоростью   последующее приведение результатов в различных интервалах скважин к единой скорости, отличающийс  тем, что, с целью повышени  производительности и точности каротажа по долгоживущнм изотопам-индика- горам, фон измер ют после измерени  общего эффекта от наведенной и естественной радиоактивности по пропгест- вии паузы при налг'чии в активированной руде изотопа-помехи более долго- живущего, чем изотоп-индикатор, а длину зонда, скорость спуска прибора и длительность паузы выбирают с учетом- посто нных распада изотопов-помех и необход1?мой точности измерений.NEUTRON AJCTIIBA-PIONE KAPOTA; | U \ method, which includes continuous measurements of the background and the total effect of the induced and natural radnoakt-ganosti when moving the downhole device with a constant uninterruptedly recorded speed, then bringing the results borehole intervals to a single rate, characterized in that, in order to increase productivity and accuracy of logging on long-lived isotopes-indicators, the background is measured after measuring the total effect of induced and natural radioactivity on prop Because of the pause in the activated ore of the isotope, the interference is longer than the isotope indicator, and the length of the probe, the rate of descent of the device and the duration of the pause are chosen taking into account the constant decay of the isotopes and the necessary measurement accuracy .
