However theoretical analysis and research has been done for along time ago, the economic tools are available in the last 1015y. Now, LWDAC can acquired pressional, shear wave and fullwave data, which can be used to understand the properties of bolehole, pipe and formation 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reserved. 6 參考資料 ?唐曉明 定量測井聲學 石油工業(yè)出版社 2022 ? ? ?………… 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reserved. 7 參考資料 ?唐曉明 定量測井聲學 石油工業(yè)出版社 2022 ? ? ?………… 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reser
