摘　　要：介绍了随钻地震(SWD)技术基本原理和现场信息处理方法,给出了利用SWD采集数据进行地层压力计算的理论模型。结合某试验井SWD技术现场使用情况,阐述了SWD技术在异常高压预测方面的应用过程,以及如何利用SWD处理结果来为技术套管下入深度选择提供依据。试验井应用实践表明,SWD技术可以用来预测井下的异常高压和埋藏深度,能够为确定探井的套管下入深度提供重要的科学依据。The basic principle and information treatment methods of seism while drilling（SWD） technology in field were introduced, and the theoretical calculation model of formation pressure by SWD data was given. Interacted with the field application in a test well, the application of SWD technology on overpressure forecast and how to use SWD treatment result to give foundation for choosing casing setting depth were elaborated. The application result indicates that the overpressure and buried depth underground could be forecasted by SWD technology, which can provide important basis for choosing casing setting depth in exploration well.
