【 摘 要 】

In oil exploration, the acoustic wave is usually generated by the hammer stroke method and then propagates to the interior of the formation. Finally, the information of oil reservoirs is obtained by inverting the reflected compressional waves. In order to make full use of the echoes, we use the reflected shear wave to inverse the compressional wave velocity and compare it with the actual measured compressional wave velocity to serve as a quicklook oil detection. COMSOL Multiphysics, based on the finite element analysis, is used to simulate the propagation process of ultrasonic waves in the physical model, which is different from the previous simulation methods. Moreover, it can provide data for other imaging algorithms quickly.
