| Abstract: | The paper introduced 3 deep holes construction in Zhuxi mining area about the drilling formation, drilling equipment, borehole structure, bit application, drill string lifting, washing fluid application, wall protection & lost circulation control and casing situation. Analysis and summery emphasized the drilling technologies of borehole structure, bit application and wall protection & lost circulation control. Some suggestions were made for deep hole construction on drilling equipment matching; outside bit diameter increasing; drilling efficiency improvement; hole deviation, especially azimuth out of tolerance and karst cave. |
