1.Select the appropriate type of drill bit based on formation lithological information, hydraulic and drilling parameters. 2.According to the hydraulic parameters to choose the corresponding nozzle, nozzle hole size grade difference should not be too large, so as not to erode the flow channel. 3.Before the drill bit is lowered into the well, 1) check that the size and type of the drill bit match the well diameter, 2) check that the nozzle is fitted, and 3) check that the specifications of the drill bit connecting wireline mating pattern and the joint match. 4.The drill bit should be lowered in accordance with the prescribed operating procedures for lowering the well, and after the drill bit has made contact with the bottom of the well, please make sure to press gently and turn slowly (drilling pressure 5-15kN, speed 60r/min). After 30 minutes, the drilling pressure can be gradually increased to normal.

TCI bit adopts high-strength and high-toughness hard alloy teeth, optimizes the design of tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape, giving full play to insert bit's high abrasion resistance and excellent cutting ability. New wear-resistant material is applied to weld the tooth surface of the steel tooth bit, which can maintain the high penetration rate of the steel tooth bit and improve the life of the cutting teeth of the bit.
