Abstract

See full text

A drilling tool is disclosed. The two ends of the drilling tool are respectively connected with an upper drilling tool and a drill bit. The drilling tool includes an axial striking part, a torsional striking part, and an auxiliary part. Under the combined action of a spring and a high-pressure drilling fluid, the hammer of the axial striking part generates an axial striking force to strike the upper housing; and the pendulum of the torsional striking part generates a torsional striking force to strike the lower housing. The reversing switch and the center tube are plugged together to simultaneously reverse torsion and axial striking forces, respectively. The high-pressure drilling fluid pushes the hammer and the pendulum to generate axial and torsional striking forces, respectively, to effectively increase the ROP and reduce the stick-slip phenomenon. The drilling tool is stable and reliable in a complex and changeable downhole environment.
