| Abstract:Wedge tungsten carbide inserts, sliding and sealed bearing, compensation system of lubricant and a new patented nozzole have been considered into the design of DKY95XHP5 geological cone bits. It will result in higher efficiency per rig. month and lower cost per footage using the drill bit and full face drilling technology in medium hard sandstone and limestone. |
