Title:

METHOD OF CASING THE PRODUCTION SEAM IN A WELL

Document Type and Number:

WIPO Patent Application WO/1990/005832

Kind Code:

A1

Abstract:

A method of casing the production seam in a well provides for stripping the production seam (19) and enlarging the borehole in a zone (20) of the production seam (19). Then the production seam (19) is closed off by an envelope (14) impermeable to liquid media and consisting of profiled pipes expanded in the process of their installation by creating pressure therein. After that, the string (5) of exploitation pipes is lowered down the well and cemented, with subsequent re-opening of the seam (19). The lowering down of the exploitation pipe string (5) is terminated after its introduction into the upper part of the impermeable envelope (14).
