| Popis: |
The common types and treatment methods of drilling accidents in directional drilling construction are described, and the principle, auxiliary salvage drilling tools, process methods and key points of reverse wire salvage technology are emphatically analyzed. The field practice shows that when the strong rotary pull-up method and casing milling salvage technology can not deal with directional drilling accidents, the reverse wire salvage technology can effectively solve the problem of drilling tools are stuck, and the maximum salvage depth is 1 152 m. |
