摘　　要：多极子阵列声波测井是继长源距声波测井之后的新一代全波列测井，其资料蕴含着丰富的地层（岩石）物理信息，在地质和工程应用中发挥着越来越大的作用。本文探讨了基于STC法的阵列声波测井资料的处理方法，并依此原理编制了处理程序，主要用以提取纵波、横波的时差数据。经实际应用检验，该程序处理精度高，与国外同类软件具有可比性。Multipole array acoustic logging,which contains rich physical information about formation(rock),is a new generation of full-wave well logging after long spaced acoustilog.It plays more and more important role in geological and engineering applications.The paper discusses the processing method of the array acoustic logging data based on STC and the processing programme compiled on the principle which is used to extract P-wave and S-wave time difference data.Practical application has proved that the program has high accuracy and is comparable with other software of the same kind abroad.
