摘要：The bonding quality of the seal formed by the cement or collapse material between casing and
formation rock is critical for the hydraulic isolation of reservoir layers with shallow aquifers,
production and environmental safety, and plug and abandonment issues. Acoustic logging is
a very good tool for evaluating the condition of the bond between different interfaces. The
understanding of the acoustic logging wavefields in wells with single casing is still incomplete.
We use a 3-D finite difference method to simulate wireline monopole wavefields in a single
cased borehole with different bonding
