摘　　要：井壁微电阻率扫描图像（FMI）以其分辨率高、图像形象直观而著称，常用于特殊地层的岩性与岩相分析、裂缝的识别与定量评价等。另外，FMI图像比较重要的一点就是它具有方向性，利用岩心刻度测井的方法，使岩心与测井图像的深度与方位都一致，这样不但可以取代昂贵的定向取心，而且还可应用在确定地层、裂缝产状及沉积环境等方面。Formation microscanner logging is well-known for its high resolving power and audio-visual images .It is useful to analyze the litho-types and litho-facies of special formations, and identificate fracture and evaluate fracture quantitatively .On the other hand ,its images have direetivity,which is important to us .If the method of core＇s scale logging is sufficiently used, and at the same time the core and logging images consists with each other ,thus we may replace costly orientational coting, also determine correctly fracture attitude of dipmeter and depositing environment
