Abstract

The mathematical modeling of acoustic waves, based on the mechanical properties of samples of cement, was done for a model of cased well. Informative parameters of waves that characterize the quality of cementing well, their frequency dependence for various gaps in the contact column-cement and cement-rock were established. Acoustic cement bond logging is carried out by probes with various frequency characteristics. By Gutorov's works (1995) the frequency dependence of amplitude of a wave on a column on gap size is experimentally shown. In this investigation, based on mathematical modeling of the acoustic cement bond logging the influence of frequency of the emitter on the parameters of acoustic waves (amplitude and velocity of waves on the column and the Lamb-Stounli wave) was investigated. Simulation was carried out for three types of cements. The results are the basis for improving data interpretation of acoustic cement bond logging in conditions of lightweight cements.
