工程勘探钻孔岩心图像管理技术

Management Technology of Engineering Exploration Borehole Rock Core Image

岩心是勘探的重要成果,传统的岩心管理方法已不适应实际工作的需要。以河南省钻孔岩心数据为例,建立了岩心图像管理系统。系统是在建立图像管理实体概念模型的基础上,借助于GDI+图像处理和文字显示技术,实现了岩心图像入库、图像绘制及图像编号,使用Image类打开和保存一个Image类对象,使用Graphics类在视图中绘制Image类对象,设计了CNNImage、CNNARowAlbum和CNNAlbum三个类用于管理三级图像;实现了岩心相册建立、岩心对比及岩心查询等功能。该系统便于勘探人员观察、处理和分析岩心信息。

Rock core is the important result of the engineering exploration. The traditional rock core man- agement methods haven＇t adapted to the requirement of current works. We develop rock core image man agement system with Henan Province as an example. On the basis of the establishment of image manage- ment entity conceptual model, the system achieves rock core image storage, image drawing and image number by means of image processing and text display technology of GDI＋. The system opens and saves an image class object by image class and draws the image class object in the view by the graphics class. We design three classes such as CNNImage, CNNARowAlbum and CNNAlbum to manage three levels image. The system provides some function to create rock core image album, compare rock core image and search rock core information. It is convenient for explorer to observe, edit and analyze rock core information.
