Coding and identification method and management system for heavy oil environmental work equipment

Abstract

The invention relates to a thick oil environment working device with a logo and a manufacturing method of the logo on the thick oil environment working device. The manufacturing method includes the step of recording a rectangular-ambulatory-plane shaped positioning icon and a long strip icon on the working device. Furthermore, the invention discloses a method and a device for identifying the logo. The method for identifying the logo includes the step: performing multi-information synchronization and identification on a code by using a two-dimensional searching and matching recognition algorithm, and realizing the digital management of the working device. Besides, the invention discloses an identity identification management system of an oil tube. According to the method for encoding and identifying the thick oil environment working device and the management system, the rectangular-ambulatory-plane shaped icon is convenient to position and identify, and also easy to record; the long strip icon is easy to record, clean and identify, and matched up with the principle of binary code; the recognition algorithm of the invention takes the two-dimensional searching and matching as the principle; by sampling a specific sampling point, the sampling frequency is reduced, the recognition scale is effectively improved and the integration of the encoding information is added; moreover, the recognition rate is greatly improved.

Description

Technical field [0001] The invention relates to a coding and identification technology, in particular to a coding and identification method and management system for working equipment in a heavy oil environment. Background technique [0002] At present, in the field of oil production, due to the complex downhole operating environment (high temperature, heavy oil, corrosion, etc.), the management of downhole equipment (such as tubing, production tools, etc.) is still in the non-digital stage. The traditional one-dimensional or two-dimensional code identification can not survive in the underground working environment, which makes the traditional identification method have a low recognition rate, cannot read the identification code information correctly, and affects the digital management of the equipment. [0003] For example, the oil production plant’s preparation brigade’s tubing repair line process such as figure 1 As shown, the main processes are cleaning, straightening, flaw det...

Problems solved by technology

[0004] In the above-mentioned process, due to the large amount of manual participation in the sorting technology and the long sorting area, there are the following main problems: (1) It is impossible to distinguish the source, service life, manufacturer, etc. of the oil pipes (new and old pipes are mixed, causing safety hazards ); (2) The long-term human eye observation causes the staff to be quite tired and the labor intensity is very high; (3) The operators in the control room are required not to leave their posts under any circumstances during the working hours; because the sorting area is too long, the human eyes Due to limitations, it is easy to misjudge the mining area where the oil pipeline belongs, which increases the workload of error correction and reduces work efficiency; (4) With the development of science and technology, manual operations are gradually replaced by machines, and the degree of automation is getting higher and higher , artificial recognition can no longer adapt to the development of contemporary economy
