摘　　要：本文根据声波速度测井仪的基本测量误差要求,对目前使用的某些仪器及一些测井实例进行了分析和讨论。文章除充分说明了补偿声波速度测井仪的优点外,还指出目前现场流行的一种测井曲线记录方法有很大的误差,对孔隙度解释及储量估计带来极大偏差,使先进的补偿声波测井仪得不到正确使用,妨碍了它的全面、合理的推广使用。This paper establishes the requirements for the errors in measurements ofacoustic velocity logging. Field examples are analysed and discussed. Thisshows the advantages of BHC acoustic velocity logging and reveals a seriousproblem in recording method currently used in oil fields, which causes a con-siderable error in log-derived porosity, and renders a large amount of errorin reserve ostimation. This problem hinders advanced BHC Acoustic VelocityLogging from proper and extensive use.
