FIELD: oil and gas production industry. SUBSTANCE: according to method, bore-hole is drilled, lowered into bore-hole is casing pipe made of material which can deform in cold state. Aforesaid casing pipe can widen in radial direction relative to wall of bore-hole at application of radial force. This casing pipe is of less resilient radial deformation than surrounding formation at application of aforesaid force. Casing pipe is also subjected to radial load and due to that it widens in radial direction relative to wall of bore-hole so as to provide compressive force between casing pipe and underground formation. EFFECT: high efficiency. 10 cl, 6 dwg
