The drilling process of the spiral drill pipe: pressurize and rotate forward at an appropriate rotation speed. It can only be carried out when the drill pipe is completely locked. Avoid pressurization during the locking process, that is, use the machine locking drill pipe as a friction drill pipe, because the forward rotation drilling during pressurization will cause the pressure pair to join and crush the lock point. -Precautions for Spiral Drill Pipe of Yikuang Science and Technology (I) According to geological characteristics, when drilling under pressure in forward rotation, the pressure sometimes needs to be alternated between "large and small", but the small pressure is not zero pressure, let alone "negative pressure". "Zero plus pressure" and "negative plus pressure" will cause the pressurization process "off-lock" and "partial lock bar" phenomenon, resulting in

auger drill pipe matters needing attention (I)
According to the geological characteristics, when the forward rotation pressure drilling, the pressure sometimes needs to be changed from "large to small", but the small pressure is not zero pressure, let alone "negative pressure". "Zero pressure" and "negative pressure" will cause "off lock" and "partial lock bar" in the pressurization process, resulting in damage to the pressurization point. -- Yikuang Technology
auger drill pipe matters needing attention (II)
According to geological characteristics, it is sometimes necessary to reverse during drilling (footage). During reverse, the pressurizing device should be raised to form a certain distance between the pressurizing pairs at the locking point to ensure that the rod can be completely locked during subsequent forward rotation pressurizing drilling. -- Yikuang Technology

That is, fully lock the rod forward pressure drilling, pressure pair away from a (longitudinal) distance reverse drilling. -- YiKuang Technology
