Application of liquidwhistle acousticgenerator to scale control and paraffin control.

液哨式声波发生器是一种机械型的流体动力式声波发生器 ,适合在液体环境下激发声波 ,在油田防垢、驱油、防蜡、降粘等方面具有广泛的应用前景。本文介绍了液哨式声波发生器的机械结构和工作原理 ,开展了声波防垢和降粘实验。经声波处理后 ,原油结垢量明显减少 。

Liquidwhistle acousticgenerator is a mechanical hydrodynamic one, which is fit for exciting sonic wave in liquid with wide applied prospect on scale control, oil displacement, paraffin control, viscosity break and other aspects in oilfield. Mechanical structure and working principle of the liquidwhistle acousticgenerator are introduced in this paper. Scale control and viscosity break by sonic wave are experimented. Amount of scale buildup of crude oil reduces obviously and viscosity of waxbearing crude reduces at large range after sonic wave treatment.
