振动法采油技术是一种利用物理方法提高油井生产效率的方法,可有效提高中后期油井产量和采收率。井下自激振动技术在井下设置振源,大大的延长了设备在井下的工作时间。井下自激振动发生装置通过在常规抽油杆工作时,管柱发生周期性弹性变形带动工作,将产生的弹性性能转换成脉冲能量,利用井下液体冲击地层发生振动,从而达到油井解堵增产的目的。振动片是该装置的核心部件,研究对振动片的影响因素,得出最优的纵向振动效果。

Vibration method oil production technology is a way to use physical methods to improve oil production efficiency, which can effectively improve oil production and recovery rate in the late. Underground self-excited vibration technology to set the vibration source in the mine, greatly extending the equipment downhole working time. Downhole self-excited vibration generating device through the work of the conventional sucker rod, pipe string periodically elastic deformation led the work will be generated by the elastic properties into pulse energy, the use of downhole liquid to impact the formation of vibration, so as to achieve oil well solution plugging stimulation purpose. Vibration plate is the core component of the device, the study of the impact of vibration of the film, the best longitudinal vibration effect.
