| Abstract: | According to the drilling technical problems in deep complex formations of the iron mine surrounding Makeng of Fujian,discussion was made on drilling technology process combination.By the combination of wire-line coring hydraulic hammer,multi-functional hole bottom reverse circulation by single swiveling and double tube coring,and borehole wall protection and circulation loss prevention（case,mud and cement）,the difficult coring,frequent borehole wall troubles and easy deviation in the complex formation were solved preliminarily,a set of drilling technologies and measures were summed up. |
