| Quantitative computation of image logging data has always been the focus of log interpretation .In this paper ,based on the methods of computing fractural and area-hole from the ultrasonic-electric image logging data obtained from Atlas tools ,realized automatic identifying fracture and aperture in imaging logging by computer .Reviewed the developing history of logging technology ,and introduced the data process system of imaging logging at home and abroad .The developing imaging logging technology is quite adaptable to logging in complex in homogeneous reservoirs and hence a leading technology in the world today.Based on the research of processing procedures and the influencing factors on logging quality .Deeply analysis the principles and methods of ultrasonic-electric image logging ,the essential technology of fracture and aperture automatic identifying is formed .On this foundation ,realize the automatic identifying of fracture and aperture by using the advanced technology of data imaging process selecting BMP file format as the storage format of imaging logging data ,using smoothing silencing of noise image enhancement, boundary detection and image segmentation object detectionBased on the researching on the methods of quantitatively calculating the fracture and aperture, and the analysis of automatic identifying outcomes ,get a new method of quantitatively calculating based on image processing.In the condition of precisely detected target area ,this method realized quantitatively calculating by the statistics of pixels number and width ,effectively improve old methods which are only can be used in FMI and just to incline fracture.From the principles and steps of aperture identify, using the technology of image and boundary detection, realized the automatic identifying of area-hole and quantitatively calculate. |
