摘要
水力振荡器通过高频轴向震动,能够有效减少钻井摩阻,施加钻压,提高机械钻速,解决钻井过程中托压、机械钻速慢的问题,其主要指标是轴向振动力、振动频率和振动位移。为进一步检测其性能指标,川庆钻采院研制了一种水力振荡器室内测试平台。应用结果显示,研制的水力振荡器室内测试平台能真实的模拟水力振荡器井下工作状态,对其功能性、可靠性和工作指标进行检验、检测,为水力振荡器的现场推广应用提供了有力的数据支撑。
The hydraulic oscillator,by high-frequency axial vibration,can effectively reduce drilling friction,exert WOB,improve ROP,and solve the backpressure problem during drilling.Its main indicators are axial vibration force,vibration frequency and vibration displacement.For further testing of its performance,an indoor testing platform for hydraulic oscillator was developed.The test run showed the testing platform could simulate the real downhole working status of hydraulic oscillator,so as to test and monitor its function,reliability,and performance,providing data evidence for field application of the hydraulic oscillator.
