【Summary Description】 When the scratch mark on the drill pipe body is about 1mm deep and is in a spiral state for more than one turn, please use it with caution. Prevent the drill pipe from being broken during construction, causing greater losses.

1.Pay attention to check the wear of each part of the drill pipe, and find out the reason in time if there is abnormal wear:

(1) Determine whether the drill pipe is scratched by the sharp hard substance in the hole;

⑵ Determine whether the drill pipe is scratched by the drill guide device.

When the drill pipe body is scratched with a depth of about1mmPlease use caution when the spiral state is more than one turn. Prevent the drill pipe from being broken during construction, causing greater losses.

2.Note that if the drill collar is found to be damaged (cross-buckling, disorderly buckling, serious wear, etc.), it should be replaced in time to damage the drill pipe thread.

3.Attention shall be paid to hoisting and handling of drill pipes to avoid impact and damage to the public buckle.

4.Pay attention to avoid mixing drill pipes with different buckle types; Do not mix drill pipes even if they are not made by the same manufacturer (because the technical parameters, processing methods, tools and mechanical equipment used by different manufacturers are different, and the tolerance and close distance of the processed drill pipes will be different); Do not mix drill pipes with too much difference between the old and the new and with too much difference in wear degree to avoid construction risks.

5.It is found that the drill pipe buckle type has a local small range (about1-2Buckle, long10mm) damage, should be repaired in time before making.

6.Pay attention to avoid clamping any part of the drill pipe body with vise clamps to avoid the rod body being clamped by slips and reduce the service life of the drill pipe.

7.Use qualified screw oil. The screw thread oil is insufficient, so that the shoulder of the joint is damaged to a high degree, which is easy to loosen the thread connection and cause thread damage. If the thread oil is not used or the thread oil is not qualified, the surface of the thread will be bonded and the thread will be glued.
