Sediment Treatment for Deep Hole Drilling in Lanzhou-Chongqing Railway
Abstract:Thick in-hole sediment affects drilling operation with drilling tool not going down to the hole bottom or drill bury. The paper introduced sediment treatment in the 3# hole of west Qingling with depth of 850m in engineering geological exploration of Lanzhou-Chongqing railway, and summed up some treatment experience and measures in treatment of sediment in broken formation for the similar drilling failure.
