摘　　要：在对天然气储集层进行开挖勘探的过程中,最重要的是要能够精准辨识、评判天然气储层。借助双向介质孔隙地层多极子敬孔生产数值模型,全方位探讨气层多极子阵列声波测井响应特点,并找出对气层变化反应较大的变量和指标,从而为气层的辨别和评判提供参考依据,从而使多极子阵列声波识别法更加完善。In the process of natural gas reservoir excavation exploration,the most important thing is to be able to accurately identify and evaluate the natural gas reservoir.With the help of the numerical model of multipole array production in two-way porous formation,the response characteristics of multipole array acoustic logging in gas reservoir are discussed in an all-round way,and the variables and indexes that respond greatly to the change of gas reservoir are found out,so as to provide reference for the identification and evaluation of gas reservoir,so as to make the identification method of multipole array acoustic wave more perfect.
