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 reserved. 8 需要掌握的內容 ?巖石的力學參數(shù) ?聲速或聲幅在巖石中的變化規(guī)律 ?井眼中聲波的發(fā)射與接收原理 ?各種聲波測井方法的原理、儀器結構、測量過程、曲線和應用 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reserved. 9 學 教方法 ?1. 通讀全書(學生) ?2. 提出問題 (學生) ?3. 提問問題(教師) ?4. 演講問題(學生 老師) ?5. 解答 解釋問題(老師 學生) ?(老師 學生) ?(學生) interaction 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reserved. 10 教材內容 Input 掌握內容 Output 學教方法 Process IPO思維方法 (如何學 激勵 興趣) 第二章 聲波測井 11/20/2022 Directed by Liu Hongqi Copyright reserved. 11 測井研究的幾個方向: 1. 理論研究:電磁場理論,彈性波動力學,核物理學,巖石力學等,數(shù)學物理方程的數(shù)值解法; 2. 計算機方法:編程開發(fā)大型商業(yè)化軟件,數(shù)值模擬; 3. 儀器的研發(fā); 4. 數(shù)據(jù)處理解釋技術,學習各種軟件。(治療) c)在媒質中傳播時能產(chǎn)生巨大的作用力,可以用來為硬質材料做切割、鑿孔等,也可以用來清洗和消毒等。超聲治療時將超聲波能量作用于人體病變部位,以達到治療疾患和促進機體康復的目的 ? 在全球,超聲波
