Acoustical well logging is an important technology for petroleum industry. Calibration and testing of tools in real wells is not feasible because the cost is high and the condition is not controllable. During manufacturing and maintaining, the logging tools are usually tested in a fluid filled circular pipe. The acoustic field in non-circular wells are calculated by using of the PDE mode of COMSOL Multiphysics Software. The received waveforms of the dipole tools in non-circular pipes are more complicated than that in the circular pipes because more modes are excited. It seems that the pipes of different sections may be used to calibrate logging tools.
