Abstract

See full text

The fixed cutter drill bit disclosed utilizes a unique piloting section and reaming section carefully designed to impart several specific operational advantages. In the piloting section, cutting structures have been arranged so as to create offsetting cutting forces that result in a net zero imbalance during operation. Furthermore, the piloting section utilizes carefully placed shock studs which aid in protecting the primary cutting structure. In addition, the location of the fluid supply nozzles on the body of the reamer section serves to indicate the occurrence of a catastrophic cutting structure failure below the pilot gage.
