Abstract
The invention discloses an embedded mark of a petroleum drilling tool, which comprises a cavity formed in an outer wall of the petroleum drilling tool, and a marker, wherein the cavity formed in the outer wall of the petroleum drilling tool is a counter bore with a flat bottom structure; a transition structure is arranged at the joint of a cavity bottom and a cavity wall; relative information of the petroleum drilling tool is engraved at the cavity bottom; information content which is the same as that of the cavity bottom is engraved on the front surface of the disc type marker; the marker is horizontally embedded in the cavity of the petroleum drilling tool; the front surface of the marker faces to the outside and sinks 1.0 mm to 1.5 mm; the surface of the marker, which faces to the inside, is parallelly hung on the cavity bottom of the cavity; as the information content of the petroleum drilling tool is engraved in the cavity, the information content is not contacted with and abraded by slurry during well drilling. The embedded mark adopting double marking has a simple and reasonable structure; the engraved information content can not be lost so as to facilitate the labor management of the petroleum drilling tool. The mark is suitable for being matched with petroleum drilling tools with different specifications, and is especially suitable for being matched with drill collars and drill rods.
Description
Technical field
The present invention relates to a kind of oil drilling tools marking structure, specifically, the present invention relates to the embedded sign of a kind of oil drilling tools.
Background technology
Petroleum drilling must use with drill collar and the drilling rod drilling tool as main body, needs order to lengthen to connect drilling tool along with well depth increases during drilling well, and the drilling tool workmanship directly affects quality of connection and drilling quality.The petroleum drilling engineering amount is large, responsibility is large and cost is large, does not allow to occur any quality accident.The industry is managed for the ease of drilling tool, and accomplishing has retrospective foundation to used drilling tool quality, and the spy is defined in the sign of scribing amount of correlated information on the every drilling tool outer wall.The drilling tool of prior art has been scribed the steel seal sign in the remarkable position of outer wall, and this marking structure is simple, scribes easily, and sign is easy to identification before installing, and the steel seal sign does not affect the normal use of drilling tool.But the mud in the drilling process between drilling tool outer wall and the borehole wall has micro-contact wear, and long term wear must diminish the steel seal sign of scribing on the outer wall, even obliterated steel seal sign.Drilling tool loses due sign except being unfavorable for field management, also loses the foundation of reviewing related responsibility when the drilling quality accident occurs, and thus, still there is fault of construction in prior art, can not satisfy the drilling quality regulatory requirement.
Summary of the invention
The problem that the present invention exists mainly for prior art, the embedded sign of a kind of oil drilling tools is proposed, this structure is located at sign in the drilling tool outer wall cavity, greatly reduce contact wear, also exempt from simultaneously bump, guarantee sign content do not lose, fuzzy, even the impaired replacing of Sign Board that embeds also is easy to.In addition, scribe identical sign in drilling tool outer wall cavity bottom, because of external Sign Board protection, built-in sign remains intact again, and the anti-lost performance of dual marking structure is good, uses safety, reliable.
The present invention is achieved through the following technical solutions technical goal.
The embedded sign of oil drilling tools, it is comprised of the cavity on the oil drilling tools outer wall and Sign Board.Its improvements are: the cavity on the described oil drilling tools outer wall is the flat-bottom structure counterbore, and the dark 3mm～5mm of cavity is provided with transition structure with wall joint portion, chamber at the bottom of the chamber, scribes the relevant information of oil drilling tools at the bottom of the chamber.Described Sign Board is disc-shaped, and scribe and the information content identical at the bottom of the chamber in the front, and the Sign Board horizontal is inlaid in the cavity of oil drilling tools, the front outwardly and sinking 1.0mm～1.5mm, one side inwardly suspends with paralleling at the bottom of the cavity chamber.
In the said structure, the cavity on the oil drilling tools outer wall is circular counter bore.Sign Board is copper board, and positive the employing is recessed into the character record related information content.
The present invention compared with prior art has following good effect:
1, setting-in Sign Board in the cavity on the oil drilling tools outer wall, simple in structure, make easily;
2, Sign Board is inlaid in the cavity on the oil drilling tools outer wall, and during drilling well and not motion contact wear of mud, sign content is difficult for being worn or losing;
3, scribe at the bottom of the cavity chamber on the oil drilling tools outer wall with the same information content of Sign Board, sign built-in under external Sign Board protection is intact, is conducive in the management with oil drilling tools;
4, Sign Board is replaceable after damaging, and reduces maintenance cost.
Description of drawings
Fig. 1 is structural profile schematic diagram of the present invention.
Embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
The embedded sign of oil drilling tools shown in Figure 1, it is comprised of the cavity 2 on oil drilling tools 1 outer wall and Sign Board 3.The cavity 2 that is located on oil drilling tools 1 outer wall is the flat-bottom structure circular counter bore, and the present embodiment PetroChina Company Limited. drilling tool 1 is Φ 100mm drilling rod, and cavity 2 dark 4.5mm are provided with the chamfering transition structure with wall joint portion, chamber at the bottom of the chamber, scribe the relevant information of oil drilling tools 1 at the bottom of the chamber.Described Sign Board 3 is disc-shaped, use the copper material manufacturing, it is positive to adopt recessed character record and the information content identical at the bottom of the chamber, and Sign Board 3 horizontal are inlaid in the cavity 2 of oil drilling tools 1, the front outwardly and sinking 1.2mm, one side inwardly suspends with paralleling at the bottom of cavity 2 chambeies.Sign Board 3 is inlaid in the cavity 2 on oil drilling tools 1 outer wall among the present invention, and during drilling well and not motion contact wear of mud, the information content of scribing on the Sign Board 3 is difficult for being worn.In addition, scribe the identical information content at the bottom of oil drilling tools 1 outer wall cavity 2 chambeies, owing to being among external Sign Board 3 protections, the information loaded content more is difficult for losing.Even Sign Board 3 damages or is fuzzy, also can at the bottom of cavity 2 chambeies, obtain relevant information, this two pass marking structure is simple, rationally, can the drop-out content in the use procedure, be conducive in the management with oil drilling tools 1.
Claims (3)
