摘　　要：参考了小振幅振动在油层中传播特性的理论分析结果,在室内实验装置上进行了低频水力振动在岩心中传播特性的实验,利用实验数据,采用量纲分析法分析了大振幅低频水力振动在岩心中的衰减规律,从而可预测低频水力振动在实际油层中的有效作用距离;同时分析了低频水力振动对岩心等效渗透率的影响,为低频水力振动改善采油技术提供了依据.Consulting the theoretical analysis results of transmission characteristic of small swing oscillation,we carry out the experimental research of the transmission characteristic of low-frequency hydrodynamic oscillation in cores with the help of indoor experimental equipment,solving the attenuation law of big swing and low frequency hydrodynamic oscillation by using the experimental data and dimensional analytic method.Consequently we can forecast the available effecting distance of the low frequency hydrodynamic oscillation in practical oil layer and at the same time analyze the effect of low frequency hydrodynamic oscillation on the equivalent permeability of the core,providing the gist that low-frequency hydrodynamic oscillation enhances oil extraction technology.
