SHARC PDC bits: The SHARC high-wear-resistant PDC bits produced by Smith International Corporation have consistently demonstrated excellent drilling performance in highly abrasive and layered formations such as cotton fields. The drill bits designed by this company using its proprietary bit design software have an extremely stable cutting structure, which allows for minimal damage and wear to the teeth, enabling maximum drilling depth without compromising the bit’s mechanical drilling speed. The SHARC drill bit has two rows of teeth on each cutting edge, which maximizes the durability of the drill bit’s head and shoulder area. The orientation of the double-row cutting teeth also helps maintain the hydraulic cleaning and cooling efficiency of the drill bit. The company holds an exclusive portfolio of wear-resistant cutting teeth designed for drilling abrasive formations, and the internal stability of the drill bits also contributes to their excellent wear resistance. FH series triple-cone bits The FH series cone bits produced by this company feature high mechanical drilling speeds, as well as excellent durability and reliability. These excellent properties stem from the following factors: the steel teeth and tooth geometry that enable the application of maximum mechanical energy to the formation ； Materials that significantly improve the durability of dentures ； Reliability achieved through durable toothed inserts, elastic components, and bearing materials ； As well as an adaptive hydraulic system that enables efficient cleaning and concentration of hydraulic energy. TCT twin roller bit: In vertical wells with deviation issues, as well as in high-displacement and high-angle wells where drill pressure is limited, the company’s TCT twin roller bit enables achieving the maximum mechanical drilling speed that a triple roller bit can provide, at a lower drill pressure. In directional wells, the TCT bit can provide the same level of responsiveness as a PDC bit or a triple-cone bit. This drill bit has fewer steel teeth/cutters than a similar three-flute drill bit, resulting in a higher point load on each steel tooth/cutter and thus maximizing the mechanical drilling speed. The bearing assembly installed on this drill bit has a large bearing area, which optimizes the force distribution, reduces the sealing load, and extends the drill bit’s lifespan. The TCT drill bit can use 4 outer nozzles and 1 central nozzle, and its vector nozzle design optimizes the cleaning of the roller cone as well as the evacuation of cuttings. The 4-point stabilization structure of the TCT drill bit reduces vibration and increases the mechanical drilling speed. This drill bit combines a tooth shank stabilizing pad with tungsten carbide inserts for protection on the back of the tooth shank, enabling it to be stable and to drill holes of full diameter. Power diamond-tipped drills The company’s power diamond-tipped drills can withstand the harshest drilling conditions, penetrate floating structures, and drill effectively in softer formations as well. In under-balanced conditions where the mechanical drilling speed is low and the footage gained is small when using conventional PDC bits or roller cone bits, this power diamond impregnated bit can also deliver excellent performance. Power diamond-tipped drills achieve extremely high efficiency when used in combination with rotary drilling tools and high-speed positive-displacement motors, and the characteristics of the drill bits can also be optimized depending on the type of drive. Powder hot-pressed teeth made from a mixed material of diamond grains and tungsten carbide matrix powder can enhance specific material properties as required. The power granular hot-pressed teeth utilize a new proprietary granulation process to achieve the best uniformity in diamond distribution. Most power drill bits are equipped with high-quality PDC teeth in the cone area to improve the bit’s crushing capacity and mechanical drilling speed. To ensure durability, these teeth are also reinforced with inlay materials. Additionally, this drill bit features thermally stable diamond teeth to maximize the protection of its diameter. In drilling applications with extremely high abrasiveness, heat-stable diamond teeth are also arranged on the shoulder of the drill bit to improve its wear resistance. The hydraulic design of this power drill bit enables it to drill efficiently at high mechanical drilling speeds in mixed lithological formations, thereby eliminating the need for drilling operations required to change the type of drill bit.
