Description

Technical Field

[0001] The utility model relates to the technical field of oil well tubing, in particular to a tubing data acquisition device. Background Art

[0002] The traditional oil well tubing generally has a tubular structure with male threads at both ends. This type of tubing has played a role in the downhole operation process of oil extraction, but it also has the following problems: it is difficult to identify its advantages and disadvantages during use, inspection, repair, and management, and it cannot detect the service life or the number of uses, often leading to difficult-to-prevent accidents due to over-service.

[0003] Chinese Patent CN205036312U discloses a tubing coupling with an electronic tag. The tubing coupling with an electronic tag includes an electronic tag and a tubing coupling. The electronic tag is installed on the tubing coupling. The electronic tag includes a housing, a tag chip, and a buffer material plate. The housing is installed on the wall of the tubing coupling, the buffer material plate is installed at the bottom of the housing, and the tag chip is located in the inner cavity of the housing. The installation structure of this electronic tag is not stable enough and is not convenient for disassembly, with relatively large limitations in use.

[0004] Therefore, we have developed a new type of tubing data acquisition device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tubing data acquisition device aiming at the defects existing in the prior art.

[0006] The technical solution of the utility model is: a tubing data acquisition device, including a chip and a tubing or a coupling. A first blind hole is opened on the outer wall of the tubing or the coupling. A stud is threadedly installed in the first blind hole. A second blind hole is opened on the side wall or the inner end face of the stud. The chip is placed in the second blind hole. A plug is threadedly installed at the outer end of the second blind hole.

[0007] Preferably, the material of the stud is cemented carbide, and its hardness is higher than or equal to the hardness of the tubing.

[0008] Preferably, a ring-shaped seat is provided in the middle of the inner wall of the coupling, and the first blind hole extends into the ring-shaped seat.

[0009] Preferably, card slots adapted to disassembly tools are opened on the outer end faces of the stud and the plug.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The chip of this device is encapsulated in the stud through a plug. The stud can be installed on the tubing or the coupling. The installation structure of the chip of this device is stable and reliable, and is convenient for disassembly and assembly, and is easy to use. Brief Description of the Drawings
