摘    要:介绍了钻孔结构设计的依据和原则,目前国内最深的岩心钻探钻孔结构和基于新的岩心钻探规程下专家建议的深孔钻孔结构。据此提出了小秦岭地区深部钻探钻孔结构的设计,建议深孔钻探必须加大开孔口径,留足用套管隔离深部复杂地层的空间。

关 键 词:深部钻探  钻孔结构  小秦岭地区

Abstract:The paper introduced the basis and the principle of borehole structure design,the deepest borehole structure of core drilling in China and the deep borehole structure suggested by the experts according to the new core drilling rules.Hereby,the design of borehole structure for deep drilling in Xiaoqinling region was put forward;the initial diameter should be enlarged to provide enough space for casing to isolate deep complex formations.
Keywords:deep drilling  borehole structure  Xiaoqinling region
