Problems solved by technology

[0003] The purpose of the present invention is to aim at the defects and deficiencies of the existing metal product marking methods, and provide a method for adding permanent and automatically identifiable marks to metal products with reasonable design and easy operation, which effectively solves the problem of downhole metal products such as pipe rod pumps Due to the indistinguishability of the old and the new, and the difficulty of distinguishing the good from the bad due to the inability to identify, it reduces operational risks and improves resource utilization

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to better understand the present invention.

[0017] Such as figure 1 As shown, the barcode mold in the method of adding permanent and automatically identifiable marks to the metal products downhole in the oil field is an 8-bit code compiled with CODE128 encoding. The material of the experiment period is stainless steel, and ordinary thin iron is used in the later stage. For hollow out.

[0018] In order to mark the used downhole metal products in the oil field, they need to be boiled to remove oil before marking, and the surface roughness of the metal is increased while local sandblasting and rust removal are carried out.

[0019] Using thermal spraying technology, two metal wires 3 of special material are used as electrodes to intersect at the end of the spray gun from the wire reel 2 through the wire feed roller 4, and the two metal w...

Abstract

The present invention relates to a method for identifying a metal product. The method is mainly used for the identification of an underground metal product such as a pipe rod pump in an exploration process tube and also can be extended to identify all metal products. According to the method, bar code compiling is included, a CODE128 encoding mode is used to compile a bar code for each metal product, and a metal mold is made for the bar code; a traditional method is used to carry out oil removing and rust removing on the partial part of the metal product and then carry out sandblasting, and the surface roughness is increased; the processed metal surface is subjected to rendering by using a thermal spraying mode; and a two-dimensional code is sprayed on a bottom surface by using a metal grinding device. The requirements of not damaging a body and no falling of the identification of the underground metal product such as a pipe rod pump are satisfied, the reading can be carried out through a scanning device, the information management is realized, old and new and good and bad products can be easily distinguished, and the utilization rate is raised.

Description

technical field [0001] The invention belongs to a marking method for metal products, which is mainly used for marking underground metal products such as pipe rod pumps in the process of oil exploitation, and can also be extended to marking all metal products. Background technique [0002] At present, there are two main identification methods for metal products: 1. Slot code technology. Including steel stamps, end markings, chemical corrosion, laser markings, etc., most of the markings are read manually, which is slow and has large errors; slot code technology will cause damage to metal products, and is easy to corrode and cannot be stored for a long time. 2. Attachment technology. Including nano-coating, spraying color code, magnetic code mark, etc., this kind of mark is easy to fall off. The above-mentioned marking method cannot meet the requirements that the marking of metal products such as pipe rod pumps cannot damage the body and is not easy to fall off. Due to the l...
