Iron-based alloys are used to overlay drill pipe tool joints and other drilling equipment by welding processes. This article describes an alloy design process that, in addition to the traditional design criteria, integrates micro-structural characterization as essential to optimize the required properties. With respect to tool joint hardbanding, two different situations need to be distinguished: openhole drilling and cased-hole drilling.
In openhole drilling conditions, wear affects the drillstring components. The wear mode involved is essentially grinding and gouging abrasion. In cased-hole conditions, although tool joint wear is an important factor, emphasis shifts to the question of how to minimize wear caused by the tool joint on the inside of the casing. The wear modes involved in cased-hole drilling are more complex, as they combine abrasion with metal-to-metal wear mechanisms.
