With the development of the internet of things technology, in various industries, an object with an intelligent label is connected with the internet through information sensing technologies and equipment such as RFID (radio frequency identification), an infrared sensor and a GPS (global positioning system), information exchange is realized, the functions of intelligent positioning, identification, tracking monitoring, management and the like are achieved, and the information intelligent management is greatly improved. In the process, the electronic tag is a unique identification number and plays an important role.

At present, RFID electronic tag drilling tools are gradually popularized and applied in the Internet of things of petroleum, natural gas and other energy industries. The RFID electronic tag drilling tool provides a great convenient means for storage, inspection, repair and management of pipe companies in various oil fields, and avoids huge and complicated work brought to the identification of the drilling tool due to the fact that the surface of the drilling tool is corroded and abraded and the steel seal number is fuzzy and unclear.

However, the oil and gas drilling tool needs to drill in a complex stratum environment, and is affected by extremely complex and harsh working conditions, high temperature, high pressure, abrasion, vibration and impact. In order to ensure that the electronic tag is safe, reliable and free from falling off in downhole use, the current mainstream mode is to directly extrude and embed the electronic tag into the surface of a drilling tool in an interference fit manner. This form of electronic tagged drill pipe presents two problems: (1) when the electronic tag is installed in an extrusion interference fit mode, electronic components in the electronic tag can be damaged, so that loss is caused; (2) because the electronic tag cannot be taken out, when the drilling tool is subjected to secondary internal coating high-temperature spraying processing, the electronic tag loses efficacy at high temperature, and a new electronic tag needs to be punched and installed, so that unnecessary economic loss is caused.

The utility model provides an electronic tag structure for drilling tool which is easy to be assembled and disassembled, which is characterized in that the electronic tag structure comprises a cylindrical electronic tag; the cylinder is locked or detached with a joint of the drilling tool through threaded fit; the center of the top of the cylinder structure is provided with an inner concave structure, and the matching of the inner concave structure and an assembling tool is used for completing the screwing of the threads on the cylinder and the joint, so that the requirements of installation or disassembly are met.

Further, the joints are blind holes in the surface of the drilling tool; the diameter of the blind hole is matched with the outer diameter of the cylinder; the inner surface of the blind hole is carved with internal threads, and the outer peripheral surface of the cylinder is carved with external threads which are matched with the internal threads of the blind hole.

Further, the external threads of the cylinder and the internal threads of the blind bore are coarse threads.

Further, the outer diameter of the cylinder is 20mm to 35mm, and the height of the cylinder is 6mm to 15 mm;

further, the concave structure is concave with a depth of 2mm to 8 mm.

Further, when the threads of the cylinder are fully tightened, the top surface of the cylinder is below the surface of the drill.

Further, the electronic tag is a metal-structured RFID radio frequency identification tag.

The utility model also provides an install the drilling tool of electronic tags structure, a serial communication port, the drilling tool contains one or more electronic tags.

Further, the drilling tool comprises a drill rod, a weighted drill rod, a drill collar, a conversion joint, a centralizer and a kelly.

Compared with the prior art, the utility model, it is showing characteristics and having:

1. the utility model discloses an electronic tags closes locking or normal dismantlement soon through screw-thread fit and drilling tool joint, can prevent that electronic tags from making the inside components and parts of electronic tags destroy because the extrusion is shaken and is hit in the installation, has also solved because interference fit leads to unable dismantlement of electronic tags and used repeatedly, easily installs and dismantles, has reduced electronic tags's use cost.

2. The utility model discloses an electronic tags is through special structural design, and electronic tags is less than the drilling tool surface with drilling tool locking back electronic tags top surface, can effectively reduce electronic tags and external collision damage and wearing and tearing.
