钻杆是钻机联接地面与井下的枢纽,介绍了一种提高钻杆联接可靠度、确保钻井排渣效率的钻杆系统。该钻杆系统采用新的进气结构和厚壁弹簧销加螺栓的联接方式,增大了进气量,提高了钻杆联接的可靠性。
Drill pipe is a joint between the ground and the downhole of drilling rig. A drill pipe system is introduced to improve the reliability of drill pipe connection and ensure the efficiency of drilling slag discharge. The drill pipe system adopts a new air intake structure and a thick wall spring pin and a bolt connection method, which increases the air intake amount and improves the reliability of the drill pipe connection.
