14 3/4”IADC 517 Tri-Cone Bit Tricone Bit Soft Rock Drilling Bits For Water Well Drilling
The three cone drill bit is a widely used core tool in petroleum drilling operations, and its performance directly affects drilling quality, efficiency, and cost. The drill bit structure consists of four main parts: the tooth palm body, the roller body, the bearing system, and the nozzle. According to the type of bearing, it can be divided into two categories: rolling bearings and sliding bearings, and according to the method of tooth fixation, it can be divided into two categories: hobbing and milling. It crushes rocks through the impact crushing effect and sliding shear effect generated by the revolution and rotation of the roller cone, and is suitable for various soft, medium, and hard strata. The International Association of Drilling Contractors (IADC) has developed a three digit coding standard for classification and selection based on tooth type, formation adaptability, and structural characteristics
