摘　　要：为解决滑动钻井过程中大摩阻问题,结合现有轴向振荡释放摩阻以及钻柱扭摆释放摩阻的原理,设计了三维水力振荡器.阐述了三维水力振荡器的工作原理,并对其关键部位阀口进行了理论分析,得到阀口过流面积以及压降随时间变化关系.分析了三维水力振荡器作用区间,在不影响导向钻具工作的前提下,确定了三维水力振荡器安放位置.以φ172mm三维水力振荡器为例进行分析,分析结果表明：当压力脉冲为0.03-2.90 MPa时,水力振荡器具有较好的轴向振荡效果.确定三维水力振荡器的作用区间为20 m,故三维水力振荡器安放位置与导向马达距离保持在20 m 以上,可保证导向马达不受三维水力振荡器影响.研究结果可为水力振荡器的现场应用提供参考.To address the large friction ol slide drilling, a three-dimensional hydraulic oscillator has been designed under the principle ol current axial oscillation and the drill string pendulum friction release. The three- dimensional hydraulic oscillator working principle has been introduced, and the theoretical analysis of its valve port has been conducted. The valve port flow area and the pressure drop versus time have been attained. The function range of the 3D hydraulic oscillator has been analyzed to determine the installation position without affecting the directional drilling tool. Taking the 0172 mm hydraulic oscillator as an example, the analysis results indicated that the hydraulic oscillator would achieve a good axial oscillation performance when the pressure pulse is 0. 03 -2. 90 MPa. The function range of the 3D hydraulic oscillator is 20 m, so that it should be placed more than 20 m away from the steerable motor.
