HIGH STRENGTH DOWNHOLE TUBULARS AND METHODS FOR FORMING AND SYSTEMS FOR USING
摘要:
Disclosed are high strength tubular devices for use in oil and gas well drilling and completions, oil and gas well intervention, and/or production systems. The high strength tubular devices include a pipe component and a secondary layer on the surface of the pipe component. The secondary layer can be either a continuous or partial layer and includes a nanostructured alloy. Alloy compositions are disclosed. Methods for forming the tubular devices are disclosed. The secondary layer can be formed on the pipe component by welding or casting. The tubular devices can be used in conductors, casing, drill pipe, production tubing, pipeline and risers.
