摘　　要：利用波动方程兵演波阻抗，由于计算工作量大、稳定性差等原因，一直没有在地震勘探资料处理中得到实际应用。本文提出的一维波动方程逐段折叠民演方法能较好地克服上还缺陷，具有计算量相对较小、精度高、稳定性好等特点，并在大庆长垣东部和西部的实际资料处理中见到了良好的效果。Wave impedance inversion using wave equation has not been used in practicalseismic data processing because of some troubles such as too much computation,poor stability and so on. Overlapped segmental inversion using 1-D wave equationcan well remove the troubles because of its quite small computation,high accuracyand good stability. The excellent effect has been seen in processing the seismic datafrom the east and west parts of the Changyuan prospect in Daqing district.
