Study on Judgment Methods of Cement Deficiency Position of Non-axisymmetric Well-hole
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.
