VP explosive bridge plug is used for installation of isolation bridge plugs in cased intervals of exploratory, production and injection wells. Explosive plugs are used in wells filled with liquid (water, flush fluid, oil) at hydrostatic pressure up to 60MPa and temperature up to 120 °С. The bridge plug is released by propellant gases. DRP black powder charge is fired from TEZ-ZP electrical igniter by current pulse along the wireline.
