摘要
水力振荡器以钻井液为动力源,将液压能转化为高频压力脉冲,能够有效提高滑动钻进过程中的钻压传递,保证工具面稳定,减小钻具与井壁之间的摩阻,减少钻具扭转振动,提高滑动钻进效率。文章主要介绍了水力振荡器在某油井中的应用情况。
The hydraulic oscillator uses drilling fluid as the power source to convert hydraulic energy into high-frequency pressure pulses,which can effectively improve the WOB transmission during sliding drilling,ensure the stability of the tool surface,and reduce the friction between the drilling tool and the borehole wall,Reduce the torsional vibration of the drilling tool and improve the efficiency of sliding drilling.The article mainly introduces the application of hydraulic oscillator in an oil well.
