Water well drilling rigs often encounter stuck drilling when they are working. Then how should we deal with water well drilling rigs stuck drilling? The following water well drilling rigs will show you how to deal with water well drilling rigs stuck drilling.
When water well drilling rigs are drilling, the most common thing is stuck drilling. Any phenomenon where the pipe column and tools cannot be lifted, lowered or rotated in the well is called stuck drilling. When encountering this phenomenon, the work of water well drilling rigs can no longer be carried out normally.
In terms of the current strength of the drill bit for drilling, the broken wing has basically been eliminated. In case of special circumstances, a seamless pipe with a diameter that is not much different from the aperture can be used. The pipe is filled with butter, asphalt, etc., and the drill pipe is connected to the bottom of the hole. Take out the broken wing at the bottom of the hole, and blow the rock powder at the bottom of the hole before salvaging.
In more severe situations, the drilling tool cannot be lifted up, can’t be put down, and the impactor does not sound. At this time, only the torque is applied or auxiliary tools are used to help the drill tool rotate, and then the drilling tool must be promoted while supplying air until the fault is relieved.When re-drilling the rock, first add a little pressure, and then gradually increase the propulsion force until the normal working pressure is reached.
Necessary inspection work before the use of the water well drilling rig
With the continuous development of living standards, the application of water well drilling rigs is also becoming more and more extensive. The following Linyi water well drilling rigs will take you to understand the necessary inspection work before the use of water well drilling rigs.
1. Check whether the oil volume of each fuel tank is sufficient and the oil quality is normal. Check whether the oil volume of each reducer gear is sufficient and the oil quality is normal; check whether there is an oil leakage failure.；
2. Check whether the main and auxiliary wire ropes are broken and whether their connections are intact and safe.
3. Check whether the extractor rotates flexibly and whether the internal grease is contaminated.
4. Check the steel strong structure for cracks, rust, desoldering and other damage.
