FIELD: oil and gas industry.
SUBSTANCE: method includes lowering a tubing string including a hydromechanical perforator comprising a dispensing unit to control the flow of working fluid, a tool or combination of process equipment for carrying out required operations in the well; supplying the working fluid through a distributing unit of the perforator under the perforator to the process equipment or into bottom of the tubing string to annular space; performing appropriate process operations by means of process equipment; feeding working fluid through the distributing unit into the perforator; performing perforation; working fluid is fed through the distributing unit of the perforator to the process equipment or into bottom of the tubing string into the annular space; performing corresponding process operations after perforation with the help of process equipment.
EFFECT: reduced time for complete complex of operations associated with perforation of wells and associated operations: milling a wellbore, cementing the well, cleaning the walls of the production string by means of a scraper, washing the well bottom with a feather, namely, carrying out a complex of operations in one running-lifting operation.
