Stickslip easily happens when PDC drill bit encounters the medium hard and soft hard formation alternately, which leads to the torsional oscillation of the drill string, the instability of the drilling process and the sharp decrease of the drilling rate. In order to solve the above problems, a high frequency hydraulic torsional impact drilling acceleration tool was put forward. The device was mainly composed of torsional impact parts, bearing connection parts and corresponding accessories. All of these were driven by the throttling differential pressure built up in internal flow channels to generate highfrequency reciprocating impact torque, and the impact of stickslip vibration on the service life of the bit was weakened or eliminated. The ground test and field application results show that the tool can output stable high frequency torque through hydraulic circulation, and has been applied in well Tao 2-4-18A, well Tuo 203 and well Yan 491;compared with adjacent wells, the penetration rate has increased by more than 30% on average. The device has a remarkble market prospect, and provides technical supports for rapid drilling in deep and ultradeep wells.
