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.
