基于摩阻和振荡力的水力振荡器安放位置计算方法

Calculation Method of Hydraulic Oscillator Placement Position based on Friction and Oscillation Force

水力振荡器是目前缓解定向托压最有效的方法之一。在大斜度井、大位移井、水平井等复杂结构井中应用越来越广泛,并取得了较好的应用效果。但目前没有形成一套水力振荡器合理安放位置计算方法,导致应用效果参差不齐。基于摩阻和振荡力,建立了安放位置计算模型,并制作了优选图版。现场应用效果表明,该安放位置计算方法有效可行。可为水力振荡器现场应用提供理论支持和技术指导。

The hydraulic oscillator is currently one of the most effective ways to relieve the directional pressure. It has been widely used in complex structural wells such as high-angle wells, large-displacement wells and horizontal wells however currently with no method for calculating the reasonable placement position of a hydraulic oscillator, resulting in uneven application results. The calculation model of the placement position based on the friction and oscillation force was established and the preferred layout was generated. The field application results show that the proposed position calculation method is effective and feasible.
