摘要
///This 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.
