To quantitatively determine the effect of different factors such as fracture width, dip angle, extension and filling material on Stoneley wave amplitude decreasing, the shock tube experiment method was changed from fixing the sample and vertically moving the sensor in the borehole to fixing the sensors along the shock tube wall and vertically moving the sample without drilling the borehole in it. The measurement accuracy and the signal-to-noise ratio of the first Stoneley wave were improved by the time corrections and amplitude corrections of Stoneley wave signals. At the same time, 21 sets of core models with different fracture parameters were processed for this measurement method by using full-diameter carbonate core, and relative amplitudes were defined to characterize Stoneley wave amplitude decreasing. The experimental results show that the relative amplitude of Stoneley wave exponentially decreases with increasing fracture width. The relative amplitude of Stoneley wave linearly decreases with increasing fracture dip angle. The relative amplitude of Stoneley wave exponentially decreases with increasing fracture extension. The relative amplitude of Stoneley wave decreases with increasing the permeability of filling material in the fracture. Under the above four conditions, the fracture width has the greatest effect on the decreasing of Stoneley wave amplitude, followed by the fracture extension and the permeability of filling material, and finally the fracture dip angle.

为了定量确定诸如裂缝宽度，倾角，延伸和填充材料等不同因素对斯通利波振幅减小的影响，将冲击管实验方法从固定样品并垂直移动到井眼中改变为沿固定传感器。冲击管壁并垂直移动样品，而无需在其中钻孔。通过对斯通利波信号进行时间校正和幅度校正，可以提高第一斯通利波的测量精度和信噪比。同时，采用全直径碳酸盐岩心，对该测量方法处理了21组具有不同断裂参数的岩心模型，并定义了相对振幅来表征斯通利波振幅的减小。实验结果表明，斯通利波的相对振幅随着裂缝宽度的增加而呈指数下降。斯通利波的相对振幅随着裂缝倾角的增加而线性减小。斯通利波的相对振幅随着裂缝扩展的增加呈指数下降。斯通利波的相对振幅随着裂缝中填充材料渗透率的增加而减小。在以上四个条件下，裂缝宽度对斯通利波振幅的减小影响最大，其次是裂缝扩展和填充材料的渗透性，最后是裂缝倾角。斯通利波的相对振幅随着裂缝倾角的增加而线性减小。斯通利波的相对振幅随着裂缝扩展的增加呈指数下降。斯通利波的相对振幅随着裂缝中填充材料渗透率的增加而减小。在上述四个条件下，裂缝宽度对Stoneley波振幅的减小影响最大，其次是裂缝的扩展和填充材料的渗透性，最后是裂缝的倾角。斯通利波的相对振幅随着裂缝倾角的增加而线性减小。斯通利波的相对振幅随着裂缝扩展的增加呈指数下降。斯通利波的相对振幅随着裂缝中填充材料渗透率的增加而减小。在上述四个条件下，裂缝宽度对Stoneley波振幅的减小影响最大，其次是裂缝的扩展和填充材料的渗透性，最后是裂缝的倾角。
