摘要
针对利用成像测井资料自动识别多裂缝过程中存在的问题,包括背景图像过于复杂和裂缝轨迹并非严格的正弦波轨迹,依据裂缝与其它地质现象形态的不同,提出了形态滤波算法和窗口扫描技术相结合的处理算法,解决了复杂地质背景下的多裂缝图像分割问题.采用Hough变换的方法对现场实际资料进行了处理与识别,取得了很好的效果.
The main problems of automatic recognition of multi-fracture from borehole images are discussed in this paper.Configuration filtering algorithm and window scan technique based on the difference between fracture configuration and other geologic phenomena in the image are first put forward.Therefore,multi-fracture image segmentation in complicated geological conditions could be settled by using this technique.Ideal results have been obtained by applying Hough transform algorithm to the identification and process of image data obtained in situ.
