摘要
综合分析了国内外大位移井钻进过程中经常遇到的几项关键技术研究进展情况 ,包括降低摩阻和扭矩技术、井眼清洗技术、井身剖面和钻柱优化设计、井壁稳定技术、套管磨损预测与防治技术等 ,并对未来的大位移井总体技术发展方向作了展望。
A comprehensive analysis is made of the development in the research of some key technologies that are often used in drilling greatly-displaced wells at home and abroad.They indude technology for reducing frictional resistance and moment of torsion,borehole-cleaning technology,optimal design of well-bore profile and drilling string,technology for stablizing borehole wall,and technoloy for predicting and preventing casing wear.A forecast is made of the future trends of development of the technologies for greatly-displaced wells.
