Abstract

Summary

Due to the influence of shallow biogas, it is difficult to get the accurate structural imaging velocity and nice identification accuracy of the thin interbedded gas layers only through P-P data. SH-SH wave with the horizontal source and PP-wave with the vertical source was directly excited and received with 3C receivers to solve the structural and reservoir characterization problems jointly. The researches show that the SH-SH wave data has a good imaging in the gas cloud area, which can recover the structural form of the gas reservoir area properly and well identify the pseudo structure caused by near surface anisotropy; SH-SH data has a higher lateral resolution than P-P data on the faults, which is good to the structure interpretation of gas reservoir; SH-SH and P-P wave data have a substantially consistent frequency range in their respective propagation time domains. After an SH-SH and P-P wave matching, SH-SH wave has a wider frequency band than P-P wave; the near-offset SH-SH wave has a higher S/N ratio than the P-P wave, thus it is much easier to identify the gas-bearing reservoir using the seismic attributes and the inversion results of the P-P and SH-SH wave data.
