In order to overcome drilling difficulties such as the poor drillability and the severe stick-slip vibration in the bouldery formation of the Permian system, as well as the tight, hard and abrasive formation in the Carboniferous system in Xinjiang Oilfield, a multi-dimensional impact tool was used to achieve volumetric rock-crushing, effective control of torque fluctuations, suppression of stick-slip vibration; thus, cutting short of the drilling duration, and reduction of the drilling incidents. The field application shows that the multi-dimensional impact drilling technology can achieve high efficient rock breaking, and increase drilling rates in formation of poor drillability and deep hard rock formation, effectively reducing the drilling cost. It is worthy of further promotion and application in suitable formations.
