Ultra-high pressure water jetting has a use for assisting mechanical breaking of rock in petroleum drilling. We found by experiment that the main factors affecting the breaking of rock are pressure, distance, speed and angle of jetting. With the pressure increasing, the breaking of rock is better and at 150 MPa, the efficiency of rock breaking is the highest. The most distance of jetting is 32.5 times diameter of nozzle when the pressure is 200 MPa, and the best jetting angle is 12.5°.

超高压水射流在石油工业中的应用主要是超高压射流联合机械破岩。对超高压淹没射流破岩规律的研究,其目的在于为超高压PDC钻头的研制提供依据。研究发现:影响超高压射流破岩的主要因素有压力、喷距、喷嘴移动速度和喷射角度等,射流压力越高破岩效果越好,最优喷距随着压力的升高而升高,200 MPa时最优喷距达到32.5倍喷嘴直径,150 MPa时破岩效率最高,喷射角度在12.5°时破岩效果最好。

超高压水射流在石油工业中的应用主要是超高压射流联合机械破岩。对超高压淹没射流破岩规律的研究,其目的在于为超高压PDC钻头的研制提供依据。研究发现:影响超高压射流破岩的主要因素有压力、喷距、喷嘴移动速度和喷射角度等,射流压力越高破岩效果越好,最优喷距随着压力的升高而升高,200 MPa时最优喷距达到32.5倍喷嘴直径,150 MPa时破岩效率最高,喷射角度在12.5°时破岩效果最好。

Ultra-high pressure water jetting has a use for assisting mechanical breaking of rock in petroleum drilling. We found by experiment that the main factors affecting the breaking of rock are pressure, distance, speed and angle of jetting. With the pressure increasing, the breaking of rock is better and at 150 MPa, the efficiency of rock breaking is the highest. The most distance of jetting is 32.5 times diameter of nozzle when the pressure is 200 MPa, and the best jetting angle is 12.5°.
