Smiths Bit Tools Company - Automated Design for Maximizing Hydraulic System Efficiency With the increasing complexity of drill bit designs, maximizing the efficiency of the bit hydraulic system will affect the ability to obtain optimal drill performance. Smith Tool Company has overcome this challenge with the flex-flo hydraulic design software system. flex-flo utilizes three hydraulic modules to deal with extremely soft, extremely viscous and abrasive extremely hard formations, respectively. The length, diameter and spray trajectory of the nozzle can be adjusted arbitrarily, so as to realize the flexible design of the jet area. The drill bit can be customized to maximize hydraulic performance with the following three flex-flo modules: The s-flo module demonstrates the flow field for three bottom-hole-pointing, similarly sized and optional length nozzles; the x-flo The module demonstrates the flow field for nozzles of optional length directed to the bottom hole, asymmetrical or significantly different; the v-flo module typically uses nozzles of similar size and optional length to demonstrate the flow field when the flow is directed to the leading side of the cone. If the bit is not adequately cleaned, it will cause mud packs, which will cause early wear of the cutting structure and limit the ROP. Because before drilling new formations, the bit cutters have to re-drill those cuttings that were not expelled in time. Ideally, the cuttings can be completely removed from the bit, but there are many different flow velocity zones downhole, dead zones with insufficient flow energy, and backflow zones where cuttings swirl. The flex-flo system facilitates nozzle combination and orientation to optimize fluid flow in different drilling environments. United Diamond Corporation - New Cutting Teeth for Continuous Drilling in Hard Abrasive Formations United Diamond Corporation has invested many years in research on the key technology of wear-resistant and impact-resistant polycrystalline diamond cutters. The cyclone cutter is one of the results of this research. Since the development of the cyclone cutters, United Diamond's pdc bits have consistently drilled harder, more abrasive formations. The combination of this composite sheet with various characteristics and the non-flat contact surface design of the substrate improves the wear resistance of the cutting teeth by 300%. Because the cutting teeth remain sharp for a long time, energy is more concentrated on the cutting edge without lossy sliding on the wear surface. The cutters eat into the formation, allowing the bit to stably drill into harder formations. United Diamond has applied this cutter to an optimized bit through proprietary bit design software, increasing the bit's stability and durability in harsh formations. The software can simulate the design of the drill bit, and can demonstrate how the drill bit works under different drilling conditions and penetration depths; it can customize the characteristics of the drill bit to ensure that all cutters have a consistent penetration depth. This design method can ensure higher stability of the drill bit, thereby reducing the occurrence of vibration and impact loss. The strong wear resistance and impact resistance of ud516nav enable the drill bit used in the Wilder River Valley in western Alberta, Canada to continuously drill through formations containing hard quartz sandstone, flint and coal with a compressive strength of 172mpa to 241mpa.
