摘　　要：喷注式声波发生器是一种以流体为动力源的自激式水力振荡器,能有效解决油水井生产过程中的地层堵塞问题,提高地层渗透率,恢复油水井正常生产。但是,喷注式声波发生器工作参数的选择不当,往往是导致作业失败的主要原因。通过室内模拟试验,研究了喷注式声波发生器的工作特性,得到了振动频率和振幅同喷嘴直径、谐振腔深和喷距等参数的变化规律,并对其工作参数进行了优化。在孤岛油田进行了现场试验,效果显著,说明该声波发生器在现场施工中具有较好的应用效果及前景。Jet acoustic generator is designed to solve the problem of formation plug, to improve layer permeability and to resume normal production of production well, while the improper parameter combination of jet acoustic generator is always the key reason causing the operation failure in oilfields. A laboratory study is performed to investigate the operating feature of jet acoustic generator, from which the relationship data between frequency （amplitude） and structure parameters such as nozzle diameter, chamber depth and spacing is obtained. Finally, structure parameter of jet acoustic generator is optimized according to the experiment results. The application results of jet acoustic generators in Gudao block prove that it has a potential application prospection.
