摘　　要：用柱状多层理论模型,计算了裸眼井、单层套管井、双层套管井中的声波波形。分别用地层纵波、横波和套管波信息,结合三种模型对双层套管井中不同条件下水泥胶结质量进行了详细分析。指出用内层套管波列和地层波列可定性判断两层套管之间的水泥胶结质量,用外层套管波列和地层波列能判断外层套管和地层之间的水泥胶结质量。结果表明,裸眼井和套管井的声波全波资料综合分析,能较好地评价水泥胶结质量。Huang Wenxin,Zhang Chengguang,Hu Wenxiang,Wang Guangui.Analysis of Acoustic Waveforms from Bi-layered Cased Hole.WLT,1993;17(3):190～196 Calculates acoustic waveform from openhole,single layered and bi-layered cased holes by multi-layered cylindric theoretical model.Based on three different models,evaluates bond quality camented under different conditions in bi-layered cased hole with shear wave,compressional wave and waves travelling through casing.Qualitatively assesses the cement bond quality between two-layer casings with wavetrain travelling through the inner casing and the formation and assesses the cement bond quality between outer casing and the formation with wavetrain travelling through outer casing and formation.The result proves that evaluation of cement bond quality can be successfully made through synthetic analysis of acoustic full wavetrain from both openhole and cased hole.
