| Abstract: | Drilling construction is very difficult in the complex formation of Daxigou mining area in Song County of Henan Province with multi-structure and broken brittle fragment formations. Water gushing, leakage, diameter shrinkage and block-falling occurred frequently with some boreholes abandoned. According to the formation characteristics and construc- tion difficulties, pertinent technical measures were taken in equipment selection, borehole structure, washing fluid and cementing with good effects. The experience of drilling construction was summed up in this paper. |
