摘　　要：对国内外深井超深井井身结构设计以及所采用的套管与钻头系列进行的调研和分析表明,我国目前在深井超深井钻井中采用的套管与钻头系列较单一,对钻井液的依赖性太强,难以满足深井超深井钻井的需要。而国外在深井超深井钻井中采用了多种套管与钻头系列,其适应范围广,有较灵活的选择余地。通过研究,推荐了可应用于我国深井超深井钻井的六种套管与钻头系列。The investigations and analysis of well bore structure designs and casing and bit series used in deep and ultra-deep wells at home and abroad show that the casing and bit series used in such wells in China at present are too simple and too dependent on drilling fluids to meet the requirements. The authors introduces 6 kinds of casing and bit series suitable to deep and ultra-deep drilling in China by various researches.
