Drill rod label capable of resisting high temperature and high pressure

Abstract

The invention belongs to the technical field of RFID tags, and particularly relates to a drill rod label capable of resisting high temperature and high pressure. The drill rod label comprises a coupling circuit chip and a stainless steel shell. A feed circuit is connected into the stainless steel shell. The feed circuit is fixedly connected with the coupling circuit chip; the feed circuit is fixedly connected with a stainless steel top plate; the upper surface of the stainless steel top plate is lower than the outer edge of the upper surface of the stainless steel shell; the stainless steel shell on the lower side of the stainless steel top plate is filled with a high-temperature-resistant filler; the coupling circuit chip and the feed circuit are completely wrapped by the high-temperature-resistant filler, the upper side of the stainless steel top plate is provided with a hydrophobic material PEEK layer, and the hydrophobic material PEEK completely covers the surface of an inner groove of the stainless steel shell. The drill rod label is stable in structure, can resist high temperature and high pressure, can prevent water, and can cope with severe environment of petroleum exploration.

Description

technical field [0001] The invention belongs to the technical field of RFID tags, and in particular relates to a drill pipe tag capable of high temperature and high pressure resistance. Background technique [0002] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets , for radio frequency, it is generally microwave, 1-100GHz, suitable for short-distance identification communication. At present, RFID technology is widely used, such as: libraries, access control systems, food safety traceability, etc. At present, with the increasing competition in the oil drilling market, the number of deep wells, exploration wells, and difficult wells is gradually increasing, and the req...

Problems solved by technology

Water has a high dielectric constant and loss. Once a water film is formed, it will greatly attenuate or even completely shield the electromagnetic signal. At the same time, during the use of the drill pipe, there will be an oil film on the surface of the label. The oil film is a mixture. The conductive ions in it will interfere with the signal of the tag, and conduct the radiator of the tag antenna with GND to form a shielding film, which will affect the use
