摘要:
A method of forming a wellbore casing within a borehole that traverses a subterranean formation, is provided by assembling a tubular liner by coupling a multi-layer tubular insert assembly to a threaded portion of a first tubular member, and coupling a threaded portion of a second tubular member to the threaded portion of the first tubular member and the multi-layer tubular insert. The tubular liner assembly is positioned within the borehole; and the tubular liner assembly within the borehole is radially expanded and plastically deformed. The multi-layer tubular insert includes a first tubular insert having a first modulus of elasticity; and a second tubular insert coupled to the first tubular insert having a second modulus of elasticity. The first modulus of elasticity is different from the second modulus of elasticity.
