摘要
特深钻探是获取深部实物资料、建立深入地球内部通道的唯一方法,在石油、天然气等能源资源勘探中发挥着愈发重要的作用。钻杆柱材料的选择和优化,是制约特深钻探发展最为关键的核心技术之一,直接影响着特深钻探的钻深极限、钻进效率和经济成本。本文从特深钻探钻杆复杂载荷工况出发,分析了钻杆柱材料面临的难题,结合钢钻杆和轻质钻杆的性能特点,针对性的梳理了国内外深井钻杆柱解决方案,并综述了钢钻杆强韧化调控、钻杆耐腐蚀性处理和应力集中处理三个关键技术,为特深井钻杆柱发展研究提供了参考依据。
Extra-deep drilling is the only way to obtain deep physical data and establish a deep channel into the earth’s interior,which plays an increasing important role in the exploration of oil,natural gas and other energy resources.The selection and optimization of drill pipe material is one of the most critical core technologies that restrict the development of extra-deep drilling,which directly affects the drilling depth limit,drilling efficiency and economic cost of extra-deep drilling.This paper analyzes the problems faced by drill pipe materials from the complex loading conditions of extra-deep drilling drill pipes,combines the performance characteristics of steel drill pipes and lightweight drill pipes,compiles the domestic and international solutions for deep-well drill pipes,and summarizes the three key technologies of steel drill pipe toughening and regulation,corrosion-resistant treatment of drill pipes,and stress-concentration treatment,which provides a reference for the research on the development of extra-deep drilling drill pipes.
