Recent studies have revealed the great potential of acoustic reflection imaging logging in detecting near borehole geology structures. One of the main issues concerning acoustic reflection imaging logging is reflection wave separation. However, the overlapping of these reflection waves (PP wave, PS/SP wave, SS wave) increases the difficulties in making use of individual reflection wave properly. In this paper we have developed an effective wave separation algorithm and corresponding code for acoustic reflection image logging, by accommodating the PRT to the borehole environment for reflection wave separation and extraction. The parameter related to curvature between seismic and borehole acoustic for PRT have been analyzed and determined. The extracted reflections can then be used for better migration and imaging of near borehole geological structures. Applications to the numerical modeling data from different interface models (not shown here as the limitation of length) and the field data from a well in an oil field in the southwest of China have demonstrated the validity and capability of our PRT algorithm.
