How to deal with the sticking of water well drilling rig
When the water well drilling rig is drilling, the common problem of Z is sticking. The phenomenon that the pipe string and tools cannot be lifted, lowered or rotated in the well is called sticking. In case of this phenomenon, the work of the water well drilling rig can no longer be carried out normally
Drilling is based on the strength of the current drill bit, and broken wings have been basically eliminated. In case of special circumstances, a section of seamless pipe with a diameter almost the same as the hole diameter can be used. The pipe is filled with butter, asphalt and other objects, which are connected with the drill pipe and enter the hole bottom. Take out the broken wings at the hole bottom, and blow out the rock powder at the hole bottom before fishing.
In severe cases, the drilling tool can't be lifted or put down, and the impactor doesn't sound. At this time, only apply torque or use auxiliary tools to help promote the drilling tool to rotate, and then raise the drilling tool while supplying air until the fault is removed. When drilling again, first apply a little pressure, and then gradually increase the propulsive force until the normal working pressure.
