    摘要:

    山东招远大尹格庄3000 m科学钻探项目是在胶东地区招平断裂带处施工的最深科学钻探项目,设计钻孔深度为3000 m。为达到提高钻探施工效率、降低孔内事故概率的目的,本项目采用高效稳定的XY-9DB型变频钻机、自主研发的高效长寿命金刚石钻头、CHD76系列高强度钻杆及联合研发的LZRT360型钻井液离心机,采用了P/H绳索取心液动冲击钻探技术、绳索取心涂层减阻内管技术等关键技术,进行深孔钻进施工,并针对不同地层进行了冲洗液体系的优选。该项目终孔孔深3120.35 m,终孔孔径78 mm,平均岩心采取率95.6%,平均矿心采取率97.9%。本文对此项目施工过程中钻遇复杂地层的处理方法、解决方案以及设备使用情况进行了总结,为类似深部钻探工程项目提供了参考。

    Abstract:

    The 3000m scientific drilling project of Dayingezhuang in Zhaoyuan, Shandong Province is the deepest scientific drilling project in the Zhaoping fault zone in Jiaodong area, with a design drilling depth of 3000m. In order to improve the drilling construction efficiency and reduce the probability of accidents in the hole, the project adopts an efficient and stable XY-9DB variable frequency drill rig, self-developed high-efficiency long-life diamond drill bit, CHD76 series high-strength drill pipe and jointly developed LZRT360 drilling fluid centrifuge. The key technologies such as P/H wire-line coring hydraulic percussion drilling technology and wire coring coating drag-reducing inner pipe technology are adopted to carry out deep hole drilling construction, and the rinsing fluid system is optimized for different strata. The final hole depth of the project is 3120.35m, the final hole diameter is 78mm, the average core recovery rate is 95.6%, and the average core recovery rate is 97.9%. This paper summarizes the treatment methods, solutions, and equipment usage of complex formation drilling in the construction process of this project, aiming to provide references for similar deep drilling projects.
