The paper studies the propagation of low-frequency harmonic pressure waves in a fracture formed by hydraulic fracturing and perpendicular to the wellbore in a porous and permeable medium. The influence of reservoir characteristics and fracture (e.g., permeability, fracture width) has been analyzed. It was found that when waves propagate from a wellbore along radial fractures, the characteristic penetration distances of pressure perturbations can be significantly higher than the penetration depth of perturbations from an open well in bedding with no fracture.

垂直于井眼的水力裂缝中的谐波过滤波动力学

本文研究了低频谐波压力波在水力压裂形成且垂直于井眼的多孔可渗透介质中的裂缝中的传播。分析了储层特征和裂缝（例如渗透率，裂缝宽度）的影响。已经发现，当波从井眼沿着径向裂缝传播时，压力扰动的特征穿透距离可能明显高于没有裂缝的裸露层中来自裸眼井的扰动穿透深度。
