摘要
本文对声波在双层套管的传播及水泥环厚度对套管波幅度的影响进行了描述,对不同胶结情况下的双层套管首波幅度和到达时间进行分析,提高了对套管波所代表含义的认识,总结了声波变密度评价双层套管固井质量的方法,对评价双层套管固井质量具有借鉴作用。
The wave propagation in double casing and the influence of cement thickness on casing wave amplitude are described in the paper Through analysis of the first wave amplitude and arrival time under different cement conditions,we understood the meaning of casing wave better and summarized the evaluation method of double casing cementing quality with the acoustic variable density data.It wil provide reference for double casing cementing quality.
