Problems solved by technology

[0006] 1. The radio frequency identification tag signal is transmitted smoothly, and it cannot be completely wrapped by metal materials, resulting in signal shielding
[0007] 2. The posture of the radio frequency identification tag is unstable when it is in motion. When the radio frequency identification tag passes through the antenna, it is perpendicular or approximately perpendicular to the axis of the antenna, which affects the communication results
[0008] 3. The radio frequency identification tag wrapping material blocks the circulation channel of the underground intelligent equipment
[0009] 4. The label has poor mechanical strength, cannot withstand impact, and is not resistant to temperature and pressure

Abstract

The invention provides an easy-hydrolysis RFID tag for oil drilling and a preparation method. The tag comprises a shell and an RFID tag body. The shell is in the shape of a water drop and is prepared from easily-degradable material. The shell comprises an upper shell and a lower shell in butt joint. The tag is prepared through a mold vacuum solidification method, so that the tag can control the movement direction of the tag when moving under a well, and package material is quickly degraded after the RFID tag achieves the goal of information delivery, in case of obstruction of a liquid outlet of under-well intelligent equipment which may lead to any complex under-well accident.

Description

technical field [0001] The invention belongs to the technical field of wireless information transmission, and in particular relates to a downhole easily hydrolyzable radio frequency identification tag for oil drilling and a preparation method thereof. Background technique [0002] Radio Frequency Identification is a communication technology that can identify a specific target and read and write related data through radio signals without the need for mechanical or optical contact between the identification system and the specific target. The advantages of its non-contact automatic identification technology are more and more used in the oil drilling industry. [0003] Existing information shows that many companies have applied radio frequency identification technology to underground intelligent equipment. When in use, the unique information code is first implanted in the radio frequency identification tag. When working, put radio frequency identification tags carrying differ...
