Abstract: Aiming at the problems in process of fiber video well logging processing, a novel technique of automatic apertures identification and processing is proposed, which uses selective Gauss Laplace edge detection and annular two-way rectangular box scanning technique to implement automatic aperture identification. It corrects apertures information in the database automatically with special algorithm, and estimates whether the aperture produces oil by calculating margin of certain pixel counts. Simulation experimental results demonstrate this technique can get a fast processing speed and high accuracy rate, which has the value of application.

Key words: aperture identification, Gauss Laplace edge detection, two-way rectangular box
