特深岩心钻孔套管程序和钻具级配等问题的探讨

Discussion on Casing Program and Drilling Tools Match Relation of Ultra-deep Geological Core Hole

摘要:

讨论了特深岩心钻孔钻探施工的套管程序、钻具及其级配和固井等问题，深入分析了这些技术问题对特深孔钻探施工的风险性和经济性的影响作用。在分析研究的基础上，提出了对我国施工特深岩心钻孔时的套管程序、钻具级配、特深孔钻杆柱、套管柱以及固井等技术方案的建议。

Abstract:

In this article some technical questions, such as casing program, drilling tools and their match relation and cementing for the drilling operation of ultra-deep geological core hole have been discussed. The influence of these technical factors on the risk and economics of drilling operation of ultra-deep geological core holes are analyzed. On the basis of analytical study, proposals on the casing program, drilling tool match relation, ultra-deep drill string and casing string schemes and cementing program for the drilling of ultra-deep geological core holes are put forward.
