Method for installing drilling tool electronic tag

Abstract

The invention provides a method for installing a drilling tool electronic tag. A round groove is drilled in a cylindrical surface of a drilling tool joint, the outer periphery of the round groove is provided with a tag pedestal, the inner periphery of the tag pedestal is provided with a layer of thermal-insulation insulating material, the inner periphery of the thermal-insulation insulating material is provided with a cylindrical antenna, the center of the bottom of the insulating material is provided with a round hole, the round hole is internally provided with an electronic tag chip, and the outer periphery of the electronic tag chip is provided with a layer of a sealant. The electronic tag chip is a high temperature cylindrical electronic tag chip, on end of the electronic tag chip is welded with the tag pedestal, the other end of the electronic tag chip is welded with the antenna, and the electronic tag chip sends electronic tag signals or receives external instruction signals through the antenna. A part for installing the electronic tag chip is novel, compact and reasonable in structure, so that an innovative method for installing the electronic tag chip is provided. The installation process is simple, firmness and stability are achieved, the service life is prolonged, and information transmission of the electronic tag chip and safety of drilling well construction are ensured.

Description

technical field [0001] The invention relates to an electronic tag for an oil drilling tool, in particular to a method for installing an electronic tag for a drilling tool. Background technique [0002] It has become a consensus to adopt the method of secondary packaging and embedding electronic tags on the drill collar, and many universities and companies have also proposed various protective installation methods based on this. Including: secondary packaging engineering plastics, heat insulation filling layer method and embedded fixing method. Its problems are as follows: [0003] 1. The casing used in the secondary packaging method is high-strength engineering plastics. During actual installation, a large area of ​​plastic on the front of the label is exposed in the underground environment full of high temperature, high pressure, and debris mud, and is always subject to debris and high-pressure mud. It is easy to be damaged due to impact and scratching; some drilling tool...

AI Technical Summary

Problems solved by technology

[0005] (1) The electronic tag installed by thread connection must have a force point on the front, otherwise the tag cannot be installed in the concave hole on the drill collar, which destroys the integrity of the surface and is more likely to be scratched by cuttings leading to breakage and ultimately damage to the entire label, this technique is unreliable

(2) The method of fastening glue is easily affected by the aging of the glue caused by temperature changes, so it is usually used in conjunction with other installation methods, usually as an auxiliary fastening method; (3) The method of clamping the ring, in When there are gaps around the downhole circlip, the downhole mud flows and is corrosive, which makes the circlip easy to corrode and lose its elasticity, causing the label to fall off
