However, in severe cases the microannulus may encircle the entire casing circumference.
但是在严重的情况下，微环隙可围绕整个套管圆周。
The dependence of amplitude of first break for acoustic logging in cased borehole on the thickness of microannulus is studied in this paper with Finite Element Method (FEM).
本文采用有限元计算方法研究了微环厚度对套管井声波测井初至波幅度的影响。
