在鑽探过程中,合理的掌握軸心压力是提高纘進效率的重要因素之一。如果軸心压力小于孔底所需要的压力时,則影响進尺,当軸心压力大于孔底所需要的压力时,容易造成鑽杆折断、孔斜等事故,同样影响進尺。所以,每个操作人員在鑽進过程中,合理的掌握軸心压力是十分重要的。用秤重法計算軸心的压力,办法簡單,在計算軸心压力时不必考慮鑽杆及粗徑鑽具的長度、重量、鑽
In the drilling process, a reasonable grasp of the core pressure is one of the important factors to improve efficiency. If the axial pressure is less than the required pressure at the bottom of the hole, it will affect the footage. When the axial pressure is greater than the pressure required at the bottom of the hole, it is easy to cause the drill pipe to break, hole slash and other accidents, affecting the footage as well. Therefore, every operator in the drilling process, a reasonable grasp of the axis pressure is very important. Calculate the pressure of the axis with the weighing method, the method is simple, in calculating the axial pressure without considering the length of the drill pipe and the diameter of the drill, weight, drill
