The problem of dealing with the tack of the pipe column is considered as two independent tasks: prevention and elimination. Regulation of the properties of drilling flushing fluids
is an effective preventive measure to prevent the occurrence of tacks. The installation
of oil baths, despite the effectiveness, in some cases, especially when drilling at great depths, turns out to be fruitless. To increase the effectiveness of the fight against the tack of the drilling tool, it is necessary to bring the parameters of the bath fluids in accordance with the drilling flushing fluid located in the well, and also apply the technology of installing a bath that prevents their mixing.
