电成像测井在碳酸盐岩缝洞评价方面,得到了广泛的应用.然而纯人工进行缝洞的拾取和评价,劳动效率极低,且受人的影响较大.本文探讨利用最大类间方差法进行图像分割,自动划分出裂缝孔洞,进而提取缝洞相关参数.试验证明此方法效果很好.
電成像測井在碳痠鹽巖縫洞評價方麵,得到瞭廣汎的應用.然而純人工進行縫洞的拾取和評價,勞動效率極低,且受人的影響較大.本文探討利用最大類間方差法進行圖像分割,自動劃分齣裂縫孔洞,進而提取縫洞相關參數.試驗證明此方法效果很好.

Electrical imaging logging has been widely used in the evaluation of fracture and cave in carbonate.However manual evaluation of fracture and cave in carbonate is inefficient,and it is influenced by operator's experience.This paper explores OTSU method for image segmentation,for which can segment fractures and caves from the background automatically to extract the relevant parameters.It proves that this method works well.
