Design considerations for a hard-rock PDC drill bit
Description:
This paper discusses the potential for developing a polycrystalline diamond compact (PDC) drill bit for hard-rock applications such as geothermal drilling. It is concluded that in order to use the inherently efficient drag cutting process in such severe applications, measures must be taken to reduce cutter penetrating forces in order to prevent thermally-accelerated cutter wear and thereby improve bit life. A procedure is developed for determining the conditions under which waterjets can be eff…
