具有非同步振荡器的钻井工具及其使用方法
摘要：
使用非同步振荡器来钻探井筒的设备和方法。一种用于钻探井筒的设备包括油管柱和联接到该油管柱的底部钻具组合。该底部钻具组合包括第一振荡器和第二振荡器。第一振荡器被构造成以第一频率限制油管柱中的流体流并在油管柱中引起压力脉冲。第二振荡器被构造成以第二频率限制油管柱中的流体流并在油管柱中引起压力脉冲。该第一频率不同于第二频率。
摘要（英）：

Apparatus and method for drilling a wellbore using non-synchronous oscillators. An apparatus for drilling a wellbore includes a tubing string and a bottom hole assembly coupled to the tubing string. The bottom hole assembly includes a first oscillator and a second oscillator. The first oscillator is configured to restrict fluid flow and induce pressure pulses in the tubing string at a first frequency. The second oscillator is configured to restrict fluid flow and induce pressure pulses in the tubing string at a second frequency. The first frequency is different from the second frequency.
