FIELD: oil-and-gas industry.
SUBSTANCE: group of inventions relates to the method and the device for setting of inflatable packer in a subhydrostatic well. An assembly for inflatable packer setting contains a flexible pipe, an inflatable packer, a back pressure valve and a drain valve. The back pressure valve is located upstream the inflatable packer and designed with a possibility of prevention of inflation of the inflatable packer when it moves from the well surface to the packer setting site.
EFFECT: drain valve is located downstream the inflatable packer to providing a flow of the fluid medium through it and prevention of inadvertent inflation of the inflatable packer.
