  摘要:为了解决实物岩芯在取样、运输、存储与管理等方面存在的问题,提出了以电子岩芯替代实物岩芯并建立电

  子岩芯库的技术。该技术以高清钻孔电视提供的完整、清晰的孔壁图像数据为基础,利用孔壁图像与实物岩芯的

  耦合原理实现了电子岩芯及电子岩芯数据库管理系统。在实际应用中有效地解决了实物岩芯存在的问题,还提高

  了地质钻孔勘探的效率。目前,在云南乌东德水电站中进行了一系列工程应用,取得了非常好的效果。

  Abstract:To solve problems of sampling, transport, storage and management of actual core, the technique of elec

  tronic core, which is used to replace actual core, is presented, and the establishment of electronic core database is

  put forward. Based on high quality images provided by high definition borehole TV, an electronic core model was

  established, and the database system of electronic core was formed in accordance with the principle of coupling be

  tween the image of hole wall and the actual core. The system has functions of pre processing, storing, searching,

  analyzing and plotting, as well as maintaining and managing of the electronic core. By using this technique, prob

  lems of the actual core can be effectively solved in project, and the efficiency of bore drilling exploration can be im

  proved. At present, this technique has been applied to Wudongde hydropower station very well.
