FIELD: oil industry.
SUBSTANCE: device for complex treatment of face-adjacent well zone has thermal gas-generator charged with fuel with electric igniter and pipe-shaped container with acid solution, made with perforation apertures, both mounted on rope-cable. Acid solution is positioned in thermal-melting hermetic tank inside the container. Device is additionally provided with depression chamber and impact-wave effect chamber, containing remotely controlled fast-action locks, with two packers, mounted at ends of pipe-shaped container. Packers are opened under pressure from gases from gas generator. After operation of gas generator is finished, packers release pipe-shaped container. Depression chamber, impact-wave effect chamber and gas generator are jointly connected.
EFFECT: higher efficiency.
