Smith Drill Tool Company - Automated design for maximizing the efficiency of current hydraulic systems
As bit designs become more complex, the ability to maximize the efficiency of the bit hydraulic system will affect the optimal performance of the bit. Smith Tools used the flex-flo hydraulic design software system to overcome this problem. The flex-flo utilizes three hydraulic modules to handle extremely soft, extremely viscous and abrasive extremely hard formations. The nozzle length, diameter and spray path are arbitrarily adjustable to achieve a flexible design of the jet area.
With the following three flex-flo modules, the drill can be tailored to the actual requirements to maximize hydraulic performance:
The s-flo module demonstrates three flow fields pointing to the bottom of the well, with similar dimensions and length options;
The x-flo module demonstrates the flow field of a nozzle that is directed to the bottom of the well, asymmetrical or distinctly different lengths;
The v-flo module typically uses nozzles of similar size and length to demonstrate the flow field when the flow is directed toward the leading side of the cone.
If the drill bit is not adequately cleaned, it will cause mud packs, which will cause early wear of the cutting structure and limit the rate of penetration. Because the drill cutting teeth have to repeatedly drill cuttings that are not discharged in time before drilling a new formation. Ideally, the cuttings can be completely removed from the drill bit, but there are many different flow zones, dead zones where the flow energy is insufficient, and recirculation zones where the cuttings are convoluted. The flex-flo system facilitates nozzle combination and orientation to optimize flow systems in different drilling environments.
United Diamond Corporation - new cutting teeth for continuous drilling of hard abrasive formations
United Diamond Corporation has invested in researching the key technology of wear-resistant and impact-resistant polycrystalline diamond cutting teeth for many years. The cyclone cutting teeth are one of the results of this research. Since the development of the cyclone cutting teeth, Union Diamond's pdc drills have been able to drill harder, more abrasive formations.
This composite sheet with various characteristics combined with the non-flat contact surface design of the substrate improves the wear resistance of the cutting teeth by 300%. Because the cutting teeth maintain sharpness for a long time, energy is more concentrated on the cutting edge without loss of wear on the wear surface. The cutting teeth are eaten into the formation so that the drill bit can be stably drilled into a harder formation.
Union Diamond applies this cutting tooth to the optimized drill bit through proprietary bit design software, increasing the stability and durability of the drill bit in harsh formations. The software enables the simulation of the drill bit to demonstrate how the drill bit works under different drilling conditions and plunging depths; it is possible to select features for the drill bit to ensure consistent cutting depth for all cutting teeth. This design ensures higher stability of the drill bit, which reduces vibration and shock loss.
The strong wear resistance and impact resistance of ud516nav have enabled the drill bits used in the Wilder River Basin in western Alberta, Canada to continue to penetrate the formations with compressive strengths of 172mpa to 241mpa containing hard quartz sandstone, vermiculite and coal.
