摘要
Drilling is difficult for coring in large diameter deep hole because of large diameter, complex formation and borehole structure with immature drilling technology. According to the construction of the section of 0～897.66 m of hole WFSD-2, this paper introduced the main problems and technical measures in construction. Comparative analysis was made on different construction technologies and technical methods, and some suggestions were put forward.
