Structure Characteristics
The bearing composite rubber seal ring adopts the high saturated nitrile rubber with high wear resistance, which has better wear resistance and high temperature resistance; the compression ratio and section diameter of the seal ring are optimized to improve the sealing performance of the seal ring; the assembly structure of the embedded seal ring with the inner hole groove of the roller is adopted, so that the sealing of the drill bit can be kept effective even if the shirttail t is worn, and the service life of the drill bit can be prolonged.
The bit is made of cemented carbide inserts with high strength and toughness for oil. According to the compressive strength and drillability of different formation, the specific cutting structure, inserts shape and inserts material are selected to ensure the wear resistance and toughness of inserts can reach the optimal matching and have a high ROP. The steel bit adopts the wear-resistant wieldingmaterial independently developed and manufactured by Shareate and the wear-resistant material is fully wrapped on the tooth surface, which not only maintain the high mechanical drilling speed of the steel bit, but also improve the cutting tooth life of the bit.
