FIELD: oil and gas industry.
SUBSTANCE: well completion method consists in providing at least one base pipe with coating made from porous material, capable of being expanded and capable of taking the shape in compliance with objects adjacent to it. The above base pipe with external layer of soft material is lowered to well bore to the specified location. Soft material is allowed to cover annular gap to wall of well shaft without expansion of base pipe. Filtration of fluids is provided through soft material to base pipe.
EFFECT: improving filter reliability and filtration efficiency in well shaft with uneven surface, and simplifying the design.
