( 1 ) When the drilling should be possible to enhance the pump pressure , increase water power drill , much to bring interaction parameters and mechanical parameters of rock breaking water , improve the efficiency of rock breaking . Cone bit
( 2 ) In their next time to start drilling into the well , there must be costing drilling , once found several consecutive points costs rising, it is timely for tripping
( 3 ) Based on drilling and formation energy of formation of the reference level value of adjacent wells to determine what kind of choice , to footage and more, faster and wear normal drill .
( 4 ) In the drilling operation is very smooth when needed , and when to send the drill to be very uniform , do not mention Meng Meng put Dayton slipped drilling and drilling
( 5 ) If you hold the tricone bit and drill jump occurs when a continuous , if not in the device on the ground problems , you should immediately from the drill to avoid off -cone .
( 6 ) If it had not discovered footage , but the pump pressure is increased or decreased significantly , the mechanical drilling speed suddenly drops , the torque is increased and so , if the ground equipment , no problem should be checked from drilling .
