Abstract

In a series of non-axisymmetric well-hole sound filed, besides judging the channelling type according to characteristics of different sound fields, judgment of cement deficiency position of channelling well-hole is also important. The essay put forward to arrange a series of receivers around the wall of a well, adopt the one-shot eight-receiver device and the three-dimensional finite difference method to simulate various non- axisymmetric well-hole sound fields, select amplitude or travel time of the first wave as the reference and determine the deficiency position of non-axisymmetric sound fields so as to provide theoretical basis for practical well measurement.
