Method for preparing casing for use in a wellbore |
摘要 |
A method for preparing casing for use in a wellbore such as for example, in preparation, for use to line a borehole through a formation or to act as a drill string and thereafter to remain in hole. In the method, a device supporting the use of the wellbore casing is crimped onto the outer surface of the casing. The device supporting casing use can be to facilitate run in through the borehole, to maintain positioning relative to the borehole, to accommodate wear against the wall of the borehole into which the casing is run or to enhance the results of cementing. The devices supporting the use of the casing are attached by crimping to the casing to create a connection having structurally significant axial and torque load transfer capacity.
