Drilling tool code recognition system

Abstract

The invention relates to a drilling tool code recognition system comprising coding chips, a portable infrared scanner and a computer, wherein coding chips are two round anti-corrosion hard-plastic flakes with small holes in the centers, and each flake is engraved with a two-dimensional digital code of the same drilling tool; a blind hole is drilled in an area on a male connector of the drilling tool, adjacent to a slope table shoulder side, one coding chip is placed at the bottom of the blind hole, an anti-corrosion fluororubber pad with the outer diameter same to the size of the blind hole is covered on the coding chip, the other coding chip is placed on the fluororubber pad, with the surface engraved with the two-dimensional digital code upward, and finally, a small quantity of steel adhesive is applied on the inner side of the blind hole, tightly adjacent to the coding chips, so as to fix the coding chips; the corrosion and high-temperature resistant fluororubber pad in the coding chips can be used for isolating the chip at the bottom layer with a working environment so as to effectively protect the chips; and the portable infrared scanner improves the efficiency and accuracy of code recognition, avoids errors caused by manually recording codes, and promotes the digitization and the informatization of drilling tool coding management.

Description

Technical field: [0001] The invention relates to a drilling tool code recognition system, which is used for the information management of various drill pipes with external threaded joints, heavy drill pipes and some downhole tools or pup joints used in oil field drilling operations. Background technique: [0002] Drilling tool coding was first used by manufacturers to mark their own products for subsequent traceability inquiries when tracking product quality. At present, this technology has been widely used. There are often two sets of codes on drilling tools, one is the mark on the product by the manufacturer, so as to uniquely mark and code its own product, and can control the entire process and production of the product from raw materials to finished products. The inspectors conduct traceability and tracing, which belongs to an internal control management system of the manufacturer. The other set is the code of the oilfield user, which is usually much simpler than the co...

AI Technical Summary

Problems solved by technology

Due to the wear and corrosion of the drilling tool during use, the code printed on the outer surface of the drilling tool becomes blurred after a period of use and cannot be accurately identified

Although the stencil on the inner side of the bore diameter of the internal thread can be preserved for a long time, it is inconvenient to print the code in the oil field, and it is also inconvenient to observe. Every time you check it, you must carefully scrub and apply the thread compound used to protect the thread. High intensity, many people are needed, and the efficiency is low
