摘　　要：声波速度测井已成为连接测井与地震的纽带,但是测井环境对声波测井的的影响因素很大,因此有效消除井眼环境影响,就显得尤为重要。从疏松地层的井眼环境对声波测井的影响入手,介绍环境影响的校正方法,特别是泥浆浸泡影响校正方法,从而求准原状地层声波速度。The acoustic velocity logging has become a link between the log data and the seismic data. It is very important to eliminate effectively the influence of borehole environment because the influence of logging environment on sonic logging is very great. In this paper, the discussion is mainly about the influence ofborehole environment on acoustic logging, and the correction method for environmental influence, especially the influence of mud immersion. The purpose to do this is to obtain the acoustic velocity of the undisturbed formation.
