Abstract
ABSTRACT The design and development of a drag bit that utilizes polycrystalline diamond drill blanks requires careful attention to hydraulic design features. For optimum performance and service life, the polycrystalline diamond drill blanks must be kept cool and clean. These critical hydraulic requirements, vital to the survival of the diamond drill blanks, were resolved by optimizing flow velocities across the cutters as well as with the proper distribution of flow volume. This was accomplished with strategically located flow re-strictors and the incorporation of numerous interchangeable carbide jet nozzles. Field test results of polycrystalline diamond cutter bit runs in Louisiana and Texas show that significant savings can be realized by using these bits in specific drilling situations.
