| Abstract: | Because of the complex formations,deep hole drilling is very difficult in Changbai polymetallic mine area.The advanced borehole structure and wire-line coring drilling were adopted;with wire-line coring pipe of the same diameter as the intermediate casing;high performance PAB solid-free flushing fluid and the drilling technology with high-level broad spectrum bit were selected.A borehole of 1505.88 m depth was fulfilled,which became the drilling depth record of Jilin Geology and Mineral Surveying and Exploring Bureau.The paper emphatically introduced the construction technology of this borehole drilling. |
