Embodiment

[0024] This example is an improvement on existing technologies, such as image 3 As shown, the prior art is an annular groove with a width of 20 mm and a depth of 1 mm formed by direct turning on the outer surface of the workpiece. After the processing is completed, the part information is recorded on the 20mm wide surface of the annular imprint groove. After the imprint of the prior art is used for a period of time, it often occurs that the imprint is blurred and unrecognizable due to wear and tear, and finally the use record cannot be completed. Without the support of accurate records, it is very easy for drilling tools to be overdue or scrapped early, resulting in unnecessary accidents and waste. In addition, the surface of the existing ring-shaped marking groove 7 is arc-shaped, so the existing marking is a ring-shaped marking 8, and most of the marking printing devices need to work on a plane to obtain excellent printing effects. However, the imprint printed on the ou...

Abstract

The invention discloses a protection method and device for a drilling tool mark. According to the protection method and device for the drilling tool mark, a marking groove is machined on the outer circle of a high-strength section of a drilling tool in the axis direction through a common standard rod milling cutter, and the drilling tool mark is printed on the groove bottom; the drilling tool mark is covered with a sealing piece corresponding to the marking groove in shape, and a leaf spring with teeth at the two ends is clamped into the marking groove so as to prevent the sealing piece from falling off. By means of the protection method and device for the drilling tool mark, drilling tool information can be conveniently printed, and the original information of the position of the mark can be preserved for a long time. The requirement for the service life of all drilling tools and tools composing a drilling stem system can be met. The sealing piece can perform the action of preventing abrasion and slurry corrosion, and thus the original information in the marking groove is better protected. The accuracy of use records is ensured. Safe use of the drilling stem system is ensured to the maximum, the occurrence rate of drilling failures is reduced, and additional drilling cost caused by handling drilling failures is reduced. The device can be reused.

Description

technical field [0001] The invention relates to a method and a device for protecting drilling tool marks, belonging to the technical field of drilling tool mark protection. Background technique [0002] In oil drilling, after each drilling tool (such as drill pipe, drill collar, tool while drilling, etc.) in the drill string system reaches a certain service life, it must undergo corresponding size re-inspection and flaw detection to determine whether it can continue to be used. Drilling tools will be forced to be scrapped after reaching the end of their service life. In order to ensure the overall reliability of the drill string system and ensure the safety of use. This requires that all drill string drilling tools have their own detailed use records, which is convenient for counting the actual use time of each drilling tool. Therefore, each drilling tool must have a clear and definite mark, which is convenient for statistics and recording of its use. So that every drilli...
