摘要：A mechanical specific energy downhole drilling assembly having a bottomholeassembly including drill pipe and a drill bit, a weight on bit and torque sub for sensing
torque, weight on bit and revolutions per minute of the drill bit; a command and controlsub for receiving input from the weight on bit and torque sub for determining
instantaneous mechanical specific energy of the downhole drilling assembly and an anti-stall tool responsive to real time mechanical specific energy information from thecommand and control sub to adjust the weight on the drill bit to maximize rate ofpenetration of the drill bit.
