What is it about?
The characteristics of natural fractures are complex and varied, which makes it difficult to detect fractures by acoustic wave. Our research introduces a more representative petrophysical model that encompasses fracture zones. Through the analysis of experimental data, the relationship between waveform characteristics and crack characteristics of sound wave is established.

Why is it important?
Experimental Investigation shows that, when considering equivalent fracture widths, an increase in the number of fractures correlates with a reduction in Stoneley wave amplitude. As the radius of fracture extension expands, the relative amplitudes of Stoneley and shear waves decrease, adhering to a logarithmic relationship with the fracture extension radius.
Perspectives
I hope that through the publication of this article, more friends in the field of acoustic detection can contact me.
