关键链法在3000 m小口径深钻工程管理中的应用

Application of key chain technology in 3000m small-diameter drilling project

摘要:

山东省第六地质矿产勘查院施工的招远水旺庄3000 m科钻项目是招平断裂带第一深孔，终孔孔深3000.58 m，历时232 d，创造了全国金矿小口径绳索取心钻探同类型钻孔效率之最。以该项目进度管理为研究课题，在前期设计中深入分析了项目施工过程中的各个环节，并用WBS对其进行分解，查找出影响工程进度的主要因素，设置汇入缓冲区，在施工过程中采用关键链法对施工进度优化并最终取得成果。关键链法使项目管理人员对整个工程有一个既动态又实时的掌控，对深孔钻探及规模性钻探工程的工期控制有重要的意义。

Abstract:

The 3000m drilling project undertaken by the Sixth Geological and Mineral Exploration Institute of Shandong Province in Shuiwangzhuang, Zhaoyuan is the deepest hole in Zhaoping Fault Zone with the completion depth at 3000.58m, operation period of 232 days, and a record in the drilling efficiency for the similar holes in small diameter wireline drilling. In this paper, the project schedule management is taken as the research topic, and the various aspects of the drilling process are deeply analyzed in the preliminary design. WBS was used to break down the work to find out the main aspects that affect the progress of the project with the import buffer set up. The key chain technology was used to optimize the drilling progress and achieved good results. The key chain technology enables project managers to have a dynamic and real-time control of the entire project, which is of great significance to deep hole drilling and large-scale drilling works.
