| Abstract: | The acoustic reflection of near borehole fractures on many planes and a curved surface was simulated experimentally. The technique of diffraction scanning migration stack for two dimensional seismic exploration was applied to the processing of experimental data, and the images of the near borehole structure were achieved. The geometrical properties of the fractures, such as the dip, location and dimension, were found from the images. The processing results are in good agreement with the actual values. |
