(1) In the drilling process. Try to promotion pump pressure, the increase of water power drill, greatly develop the hydraulic parameters and interaction of mechanical rock breaking parameters, and then to improve the rock breaking power function.
(2) In the underground space as well as the start of drilling time, must be with the bit cost accounting, once found several points in the rising cost of time, to drill the timely, prevent the formation of the cost of inputs waste.
(3) The operator according to the formation drillability value and can refer to the adjacent wells geological condition, to determine whether to choose a different energy drill.
(4) If the bit no footage, but the pump pressure is significant rise or reduce the drilling speed, reducing its mechanical suddenly, torque increase representation of the time, if the ground equipment without a problem, should immediately check drilling equipment.
(5) When the demand operators drilling to persist stable condition of the drill bit when drilling, and be very uniform, do not be hard putting and presentation slide drilling and drilling and other representation.
(6) If the successive attacks hold drilling and bit jumping representation of time, if not the last device formation, should drill, prevent knock off cone, so that the drill damaged.
