Electronic identification method for oil production string in oil field, as well as digital management method and system thereof

Abstract

The invention provides an electronic identification method for an oil production string in an oil field, as well as a digital management method and a system thereof, and belongs to the technical fieldof petroleum system digital management. The electronic identification method for the oil production string in the oil field provided by the invention comprises the following steps of welding an identification ring/plate made of a wear-resistant and corrosion-resistant metal material at a specific position on the surface of the oil production string by adopting an electromagnetic pulse welding manner; and laser-engraving an electronic tag containing information identification on the surface of the identification ring/board through a laser engraving technology. According to the electronic identification method for the oil production string in the oil field, as well as the digital management method and the system thereof provided by the invention, by means of the method, the manufacturing ofthe electronic tag which is high in corrosion resistance and capable of containing information identification can be achieved on the surface of the oil production string, the identity of the oil production string can be comprehensively managed and controlled when the oil production string is applied in any case, so that the purpose of whole-process information intelligent management of the oil production string is achieved.

Description

technical field [0001] The invention belongs to the technical field of digital management of petroleum systems, and in particular relates to an electronic identification method for an oil production pipe string in an oil field and a digital management method and system thereof. Background technique [0002] At present, the traditional method is still used to mark the information of the oil production string, that is, manually write the information identification code, or print the steel stamp or laser engraving on the oil production string, but this method cannot directly obtain the information. With the advent of the era of artificial intelligence, oilfields are also comprehensively building intelligent systems for oilfield big data and smart oilfields. Therefore, digital management systems are the future development trend. [0003] The key to the digital management system is the need to establish an electronic tag or electronic ID card for each oil production string, so th...

Problems solved by technology

[0004] However, the technical bottleneck of the intelligent management system lies in the design and production of the electronic label for identifying the information of the oil production string. The electronic label must be easy to identify, easy to decode, long-lasting and reliable

Some research institutions use electronic chips, magnetic strips, etc. as electronic tags, but it is difficult to guarantee their permanence and rel
