Abstract

An identity identification method and device applied to petroleum drill pipe operation, the method comprising: conducting a magnetic marker processing on a specific region of a drill pipe; detecting a change in a magnetic characteristic at the specific region; and upon detecting an anomaly value of the magnetic characteristic, detecting the magnetic marker of the drill pipe, and acquiring a code number of the drill pipe based on a position, width and / or magnetic anomaly amplitude information of the magnetic marker. The advantages of the present invention are: first, the invention is easy to achieve, acquiring the drill pipe code number based on the position, width and / or magnetic anomaly amplitude information of the magnetic marker; second, the invention facilitates automatic reading by a machine, in particular facilitates automatic reading of the code number during drilling in the field; and third, the invention, via the drill pipe code number, obtains identity information of the petroleum drill pipe so as to establish a record for each of the drill pipes, thus enabling the length of time each drill pipe operating under various depth, tension / pressure, vibration and mud corrosion conditions to be known, thereby achieving a more scientific drill pipe classification, thereby reducing drilling accidents, preventing excessive allowance after retiring drill pipes, and reducing overall cost of the drilling operation.

Description

technical field [0001] The invention relates to an identification method applied to oil drilling operations. Background technique [0002] In the prior art, oil drill pipe is an important tool for drilling operations. The length of each drill pipe is about 10 meters. faucets etc. The mud is conveyed downhole through the drill pipe. In the drilling operation using the rotary table drill, the drill pipe transmits the torque of the drilling machine to the drill bit downhole. The drill pipe is the longest part of the drill string. Drill pipes need to withstand tension, pressure, torsion, vibration, friction, and drilling fluid corrosion in the downhole. It is necessary to regularly evaluate the aging degree of drill pipes, classify drill pipes accordingly, and eliminate and update them in time. The current basis for grading drill pipe includes regular thickness testing and flaw detection. If you can file the drill pipes one by one, you can know the working time of each dril...
