摘要
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.
