FIELD: oil and gas industry.
SUBSTANCE: dump-bailer contains casing with holes, head for input of armoured cable, plugging agent, plug and explosive assembly additionally contains nose piece. Nose piece is connected to casing via thread, it has central through-hole that is closed by glass disc destroyed due to explosion. There is an explosive cartridge installed at specified distance from the disc. The cartridge is fixed relatively longitudinal axis of dump-bailer via fixing element in a form of a crosspiece that is at the same time a current-conducting part of electric-explosive circuit. Fabrication hole for the plug is located at the bottom side part of the casing. Dump-bailer at bottom end part is equipped with protective shield. Invention provides improvement of performed works efficiency on creating cement disconnecting bridge that allows performing different well operations.
EFFECT: device is simple in handling, use of this device ensures high quality, safety and economy of performed works.
