| 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. |
