Abstract

FIELD: oil and gas producing industry, particularly, methods and devices for completion of wells with abnormally high formation pressure. SUBSTANCE: method includes perforation of casing string in the preset interval in the medium of weighted drilling mud, running of packer 5 in well on tubing string and installation in casing string above opened interval. Tubing string is disconnected from packer plug 5, and weighted drilling mud above it with light mud which does not contain solid phase with density of 0.8-1.3 g/cu. cm. Then, tubing string is lifted from the well and run onto tubing string into casing string are assembled operation packet 1, inhibition valve 2, circulating valve 3, and cutoff valve. Then lowered equipment is set to the operating position and blind flange 7 is removed from passage channel of packer plug 5 by building up pressure above packer plug 5, and hydraulic communication with under-packer zone is restored. Then pressure in the tubing string is reduced to induce inflow of formation fluid from the exposed interval of the well. EFFECT: higher efficiency of the method of well completion with abnormally high formation pressure with simultaneous provision of safety in operation. 2 cl, 1 dwg
