Aiming at the difficulties in interpretation of some unconventional phenomena exist in the logging data of CAST-V, This paper briefly introduces the working principle of CAST-V and the theoretical analysis of the various factors which cause these unconventional phe-nomena. The impact factors for each kind of unconventional phenomena such as acoustic signal frequency, the attenuation rate of wellbore fluid, the transducer and the distances of the target, the target surface texture, target angle, target ( stratum or casing wall material) are fully verified and the degree of difference between the wellbore fluid acoustic impedance are combined with field data of typical. Through these methods, grasp and understanding of these factors by logging data acquisition and interpretation of quality of some help. For the detec-tion of casing and cementing quality, there is a positive significance to improve the detection accuracy, so as to deal with the higher require-ments of the development of the petroleum industry put forward for crack logging technology.
