Abstract: Seismic exploration has a wide investigation scope and a large spatial scale. Its data acquistion,
processing and interpretaion system are complete and it owns a high utilization rate, but its vertical resolution
is low. Acoustic remote detection logging is capable of detecting anomalous bodies that exist tens of meters
away from the borehole, which overcomes the limitation of shallow investigation depth for conventional logging
and has a high resolution in vertical, circumferential and radial directions, but dipole shear wave remote
detection has 180 degree azimuthal ambiguity, and the radial detection range is less than that of seismic
exploration. This study combines the advantages of both, and through the comprehensive analysis of the
remote detection and seismic response characteristics of the fracture-cavity geological anomalies, constrains
the remote detection azimuthal interpretation results, finely characterizes the morphology and development of
the geological anomalies, improves the lateral extension information of the remote detection logs, effectively
improves the accuracy of the remote detection interpretation, and finally forms a comprehensive evaluation
technology of acoustic remote detection logs and seismic integrated seamhole, which improves the drilling hit
probability and development efficiency of the seamhole oil and gas reservoir. The result is a comprehensive
evaluation technology that integrates acoustic remote logging and seismic to improve the drilling encounter rate
