FIELD: equipment and technology of well workover, particularly, methods of treatment of bottom-hole formation zone with subsequent completion of gas wells with abnormally low formation pressure. SUBSTANCE: method includes lowering of tubing into well; delivery of acid, in self-destroying container, to well bottom to zone of perforation; installation of hanging packer in tubing above said container; removal of packer above perforation of flow string to provide for local action of acid in well. Acid reacts with bottom wastes and carbonate rock in formation and fluid foaming to provided for carrying out of fluid and cuttings and to ensure gas inflow. EFFECT: higher efficiency. 1 dwg
