摘要 针对FMI成像测井常见的图像失真问题,根据地层沉积过程中空间小范围内岩石结构和纹理具有渐变性和相似性的原理,利用数字图形图像处理领域常用的图像修复技术进行失真图像的复原,并针对FMI图像的特殊性质进行了方法的改进。实际效果证明,该方法可以非常逼真自然地修复受损图像,并将其应用到恢复裂缝形态、准确计算裂缝参数以及消除钻具刮擦及极板污染造成的图像中非地层因素影响,从而为测井和地质分析提供地层真实的FMI图像。 In consideration of the problem of FMI image distortion in conventional well logging, based on the principle transition property and similarity of rock structure and its lamination within the small range of sedimentation, the image repair technique, which is often used for graphic and image treatment, is used for restoring the distorted images, and methods are improved in combination with the specialities of FMI images. The effect of application demonstrates that the distorted images can be easily and naturally restored by using the method and it is used for removing non-formation effects on images induced by restoration of fracture shape, accurate calculation of fracture parameters, removal of scoring from drilling tool and pad breakdown, and actual FMI images of reservoirs are provided for logging and geologic analysis.
