中文摘要：

叙述了基于ArcGIS Engine的钻孔柱状图的生成方法与思想。从建立钻孔数据库入手，以面向对象的方法进行程序设计。对钻孔柱状图的设计、柱状图表格线的绘制、岩性柱的绘制及其岩性花纹的填充进行了详细的叙述。在．NET开发平台上，利用ArcGIS Engine组件进行二次开发，以某矿区钻孔数据为例，验证了该系统的正确性，能够满足实际工作的需要。

英文摘要：

The paper described the generation ideas and methods of drilling histogrmn based on ArcGIS Engine. Starting from the establishment of the drilling database. And using object - oriented programming approach. Give a detail description on the design of drilling histogram, the drawings of histogram form lines and litho logy columns, and how to fill lithologic patterns. The system is developed on the. NET platform combined with AreGIS Engine Components. Finally, an example of data mining drilling to verify the correctness of the system can meet the actual job requirements.
