Abstract: The research and development on imaging technique based on guided waves are further conducted
to existing problems of current detecting and evaluation techniques in cased boreholes. The properties of
dispersion and leaky attenuation of A 0 mode in a steel plate, as well as the relation between the leaky at-
tenuation and characteristic impedance of the materials bonded to the back surface of this steel plate, are
analyzed. Further experimental testing for the leaky attenuation of A 0 mode and the properties of thickness
resonance mode are conducted for a steel plate, to which one side loaded with water and the other side bonded
with different materials. The results show that the properties of materials in annular space between the steel
casing and formation can be characterized effectively using the leaky attenuation of A 0 mode and the char-
acteristic impedance of the materials outside the casing obtained from thickness resonance measurement, and
the hydraulic communication status can also be evaluated accordingly. Based on these results, we designed
and developed the temperature and pressure resisting ultrasonic transducers, as well as detecting and imaging
system for cased borehole logging and evaluation. The logging results in model testing wells agree well with
the actual situations, and the good results also are obtained in cased boreholes in oilfields.
