1. Способ диагностики герметичности заколонного пространства, включающий проведение фонового гамма-каротажа, закачку за обсадную колонну труб тампонажного раствора с газообразным химически инертным долгоживущим радиоизотопом - криптоном, проведение гамма-каротажа после образования цементного камня и гамма-каротажей через заданные периоды времени, определение момента начала заколонного перетока по результатам сравнения контрольных гамма-каротажей с фоновым, отличающийся тем, что радиоизотоп вводят в порцию тампонажного раствора, размещаемую в планируемом газо-нефте-водонасыщенном интервале перфорации, колонну перфорируют против «меченого» цементного камня, выполняют гамма-каротаж, скважину осваивают, закачивают радиоизотоп и вновь повторяют гамма-каротаж в интервале расположения «метки».1. A method for diagnosing tightness of annular space, including conducting gamma-ray background logging, pumping cement slurry pipes with a gaseous chemically inert long-lived radioisotope - krypton for casing, conducting gamma-ray logging after formation of cement stone and gamma-ray logging after predetermined time periods, determining the moment the beginning of the annular flow according to the results of comparing the control gamma-ray logs with the background, characterized in that the radioisotope is introduced into the portion of the cement slurry, displaced in the planned gas-oil-water saturated perforation interval, the column is perforated against the “labeled” cement stone, gamma-ray logging is carried out, the well is developed, the radioisotope is pumped and gamma-ray logging is repeated in the “mark” interval. 2. Способ по п.1, отличающийся тем, что в качестве радиоизотопа используют короткоживущий газообразный химически инертный газ - радон, период полураспада которого составляет 3,84 сут. и гамма - постоянная 9,1·106 мкр·см2/ч·мКи.2. The method according to claim 1, characterized in that a short-lived gaseous chemically inert gas, radon, whose half-life is 3.84 days, is used as a radioisotope. and gamma - constant 9.1 · 10 6 μR · cm 2 / h · mCi. 3. Способ по п.1, отличающийся тем, что радон вводят в тампонажный раствор в количестве 0,37 Бк.3. The method according to claim 1, characterized in that radon is introduced into the cement slurry in an amount of 0.37 Bq.
