micro-annulus的參考例句
1.And the fluid micro-annulus does not affect the shape of spectra, but its existence is equivalent to lowering the acoustic impedance of the cement. 水泥膠結類型不同，反射譜的特徵亦不同；微環的存在相當於水泥環聲阻抗變小，基本不影響反射譜的形態。
2.Aimed at the cement job quality problem that the second interface is strong bonding and micro-annulus is lied in the first interface, three rock lays FEA model is established. 針對二界面固結良好，一界面存在微間隙的固井質量問題，建立了三岩層剖面的有限元模型，研究了微間隙對井筒溫度場和應力場的影響。分析結果表明，微間隙改變了井筒徑向溫度分佈的連續性；
