Устройство относится к области нефтегазодобывающей промышленности, а именно к устройствам для изоляции пластов в эксплуатационных и нагнетательных скважинах с двумя и более интервалами перфорации, а также в скважинах с негерметичными эксплуатационными колоннами. Для повышения эксплуатационной надежности устройства в кольцевой полости на корпусе размещена втулка - толкатель, на которой установлен уплотнительный элемент между обечайкой и кольцевым конусом, а обратный клапан выполнен во втулке.The device relates to the field of oil and gas industry, namely, devices for isolating formations in production and injection wells with two or more perforation intervals, as well as in wells with unpressurized production strings. To improve the operational reliability of the device in the annular cavity on the housing is placed a sleeve - a pusher, on which a sealing element is installed between the shell and the annular cone, and the check valve is made in the sleeve.
