喷注式流体声波发生器是广泛应用于油田解堵施工的解堵设备。系统介绍了喷注式声波发生器的发声和解堵机理,并推导了假设为小波传导下的波动方程来描述声波在多孔介质中的传播特性和考虑了尺寸效应的近井地带的声波传播特性,以确定声波在地层的传播半径。该技术在胜利、辽河、大港等油田近360井次的应用表明:增液幅度达162%以上,对因地层堵塞的低产井、新井以及长停井都起到了很好的解堵增产效果,取得了可观的经济效益。
Spray-type fluid acoustic wave generator is widely used in the construction of the anti-plugging block oil removal equipment. The mechanism of vocalization and unblocking of jet-injected sonic generator is introduced systematically. The wave propagation equation under the assumption of wavelet conduction is deduced to describe the propagation characteristics of sonic wave in porous media and the acoustic propagation characteristics in near-well zone considering the size effect. To determine the sound wave propagation radius in the formation. The application of the technique in nearly 360 wells in Shengli, Liaohe, Dagang and other oilfields shows that the rate of liquid increase reaches more than 162%, and plays a good role in removing and plugging stimulation of low-production wells, new wells and long-stopped wells that are clogged by strata. Achieved considerable economic benefits.
