摘　　要：引入多极子阵列声波测井资料进行煤层参数计算,通过增加的接收器阵列可以校正来自井径变化的影响,同时单极子和偶极子声波测井资料的结合可以得到准确的煤层的纵、横波慢度。首先通过数值模拟研究了煤层的单极子和偶极子声波测井响应特征,证明单极子和偶极子测井的结合才能准确获取煤层慢度参数。In this paper,multipole array acoustic logging data is introduced to calculate coal seam parameters.By adding receiver array,the influence from borehole diameter change can be corrected.At the same time,the combination of monopole and dipole acoustic logging data can obtain accurate P-and S-wave slowness of coal seam.Firstly,the response characteristics of monopole and dipole acoustic logging in coal seam are studied by numerical simulation.It is proved that the combination of monopole and dipole logging can accurately obtain the slowness parameters of coal seam.
