ABSTRACT:
A method is provided for securing a wellbore tool assembly to a wellbore tubular member, which includes a number of method steps. The wellbore tubular member is provided, and defines a surface with a substantially cylindrical shape having a selected tubular diameter. A wellbore tool assembly is likewise provided, and includes a plurality of ring-shaped components, with at least one ring-shaped component defining a cylindrical surface having a selected ring diameter which differs from the tubular diameter of the wellbore tubular member. A plurality of radial groove members and radial land members are formed on at least one of the cylindrical surface of the wellbore tubular member and the cylindrical surface of the at least one ring-shaped component of the wellbore tool assembly. The wellbore tubular member and the at least one ring-shaped component of the wellbore tool assembly are urged to differing thermal conditions to cause the tubular diameter and the ring diameter to become substantially equal. While maintaining the differing thermal conditions, the wellbore tubular member and the at least one ring-shaped component of the wellbore tool assembly are coupled together. Then, the wellbore tubular member and the at least one ring-shaped component of the wellbore tool assembly are urged to substantially similar thermal conditions to cause a radial interference coupling therebetween. Preferably, the at least one ring-shaped component operates to retain other wellbore tool assembly components in selected positions relative to the wellbore tubular member.
