摘　　要：在江汉油田地震资料处理和解释系统平台上,一直没有精度高、计算量小的波场延拓叠前深度偏移软件。因此,中国石化江汉油田分公司勘探开发研究院开展了"基于起伏地表合成平面波叠前深度偏移"的方法研究和软件研制,成功研发了PWMIGD模块,并用它在SUN工作站上处理了四川山地地震资料,得到了较好的叠前深度偏移成像剖面。该技术可以作为开展地震资料叠前正演、反演、储层预测研究的基础,丰富了江汉油田地震资料处理和解释的手段。The system platform for seismic data processing and interpretation in Jianghan Oilfield has not wave field continuation prestack depth migration software with high accuracy and less calculation. Method research and soft- ware development are conductcxt based on undulating integrated plane wave prestack depth migration. PWMIGD module is successfully developed and applied to SUN workstation for processing seismic data of Sichuan mountainous land, gaining better prestack depth migration imaging profiles. It provides the foundation for seismic data prestaek forward and inversion and reservoir predication and another way of processing and interpreting seismic data in Jiang- han （ ）ilfield.
