Embodiment 1

[0021] In this embodiment, the oil pipe with an outer diameter of 73 mm is taken as an example. The size of the coupling 2 is: the inner diameter is 73 mm, and the gap width connected in the oil pipe is 25.4 mm. It is an API oil pipe buckle, 10 buckles / inch, and the taper is 1:16; figure 1 , 2 , 3, the present embodiment establishes the annular structure carrier 1, carries the coding content of product information, then puts the identification ring tool into the middle part of the coupling 2 of the oil pipe 3 (or pipe rod), and the annular structure carrier 1 and the The connection between the collars 2 is threaded, and there is a gap between the ring structure carrier 1 and the pipe rod 3; the outer diameter of the ring structure carrier 1 is 73mm, the length is 23mm, the wall thickness is 5.0mm, and the outer diameter is threaded. , the coupling 2 buckle of the tubing 3 is: 10 buckles / inch;

[0022] The annular structure is made of metal materials such as oil pipe steel or ...

Embodiment 2

[0027] The difference from the embodiment is: taking the drill pipe as an example, the size of the coupling 2 is: the inner diameter is 150.0mm, and the gap width between the drill pipes in the coupling 2 is 12.5mm, which is an API drill pipe buckle. In this embodiment, the ring Shaped structure carrier 1 (the present embodiment is engineering plastics such as nylon material), carries the coding content of product information, then puts the logo ring tool into the middle part of the collar 2 of the drill pipe, the ring structure carrier 1 and the drill pipe 3 There is an interval between them; the outer diameter of the annular structure carrier 1 is 150.0mm, the length is 10.0mm, and the wall thickness is 10.0mm.

Embodiment 3

[0029] The difference from the embodiment is that: taking the 25.4 sucker rod as an example, the size of the coupling 2 is: the inner diameter is 34.9mm, and the gap width between the sucker rods in the coupling 2 is 10.0mm, which is an API sucker rod buckle. The embodiment establishes a ring-shaped structure carrier 1 (this embodiment is engineering plastics such as polyester resin), which carries the coded content of product information, and then puts the identification ring into the middle part of the coupling 2 of the sucker rod with a tool, and the ring-shaped structure There is a space between the carrier 1 and the pipe rod 3; the ring-shaped carrier 1 has an outer diameter of 34.9 mm, a length of 10.0 mm, and a wall thickness of 5.0 mm.

Abstract

This invention involves the marking technology, one kind of drill rod oil tube or the oil extraction rod marking method. This invention is equipped with the ring structure the carrier, carries the product information the code content, then sets it into oil tube or tube-pole connect center; states the ring structure carrier and connect between in the closer way; States the ring structure carrier with tube-pole between which remains a gap. This invention can realize the marking time which is long, the cost is low, and may work under the adverse circumstance goal.

Description

technical field [0001] The invention relates to marking technology, in particular to a marking method for drill pipe oil pipe or sucker rod. Background technique [0002] At present, there are hundreds of thousands of various oil and water wells in my country. Nearly 10 million tons of drill pipes, oil pipes and sucker rods are consumed every year. These drill pipes, tubing, and sucker rods come from different manufacturers, and the years of production and dates of downhole work are also different. Due to the needs of drilling and production operations, they are distributed in different oil and water wells, and often need to be replaced to other wells for continued use. Due to the lack of necessary identification technology and modern management methods, it is difficult to distinguish the downhole working time of drill pipe, tubing, and sucker rod in actual work, resulting in the indiscrimination of new and old pipes and rods in drilling and oil field production, and it is...
