为了减少地表对振动波的吸收,研制了井下自激振动增油器,分析了自激振动的解堵增产机理,并通过室内模拟试验研究了沉没深度、振片直径、振片间距、豁口缝等因素对自激波频率和振幅的影响,为优化设计井下自激振动增油器提供了依据。在孤岛油田现场施工多口井,效果明显,是一种不影响油井正常生产、无污染、高效的油井解堵增产处理工艺。 In order to reduce the surface absorption of vibration waves, a self-excited vibrating oil updraft was developed and the mechanism of self-excited vibration was analyzed. The depth of sinking, the diameter of vibrating plate, the spacing of vibrating plates, And other factors on the self-excitation frequency and amplitude of impact, in order to optimize the design of underground self-excited vibrating oil augmentation provided the basis. In Gudao Oilfield site construction of multiple wells, the effect is obvious, is a does not affect the normal production of oil wells, pollution-free and efficient oil well plugging stimulation production process.
