A slotting parameter extraction method for oil pipe electronic tag implantation

Abstract

The present invention provides a method for extracting slotting parameters for the implantation of oil pipe electronic tags, comprising the following steps: obtaining the length A, width B, and height G of the electronic tag; Width W 2 , Allowable groove depth H 2 and allowable slot length L 2 ; Obtain the value range of length L, width W, and deep H of the slotting of the electronic tag installation slot; within the range of length L, width W, and depth H of the slotting of the electronic tag installation slot, the fitting coupling The functional relationship between stress and stress function Obtain the first correlation between the yield strength of the material used for the tubing coupling and the length L, width W, and depth H of the slot, and fit the relationship between the RF signal strength and the RF signal strength function The functional relationship between the signal source strength required to receive radio frequency signals within a certain range and the second correlation relationship between the length L, width W, and depth H of the slot; solve the first correlation relationship and the second correlation relationship, and obtain the opening The exact values ​​of the length L, width W, and depth H of the groove.

Description

technical field [0001] The invention relates to the technical field of oil pipe couplings, in particular to a method for extracting slotting parameters for implanting oil pipe electronic tags. Background technique [0002] In the production of oil and gas operations, oil pipeline marking and usage status records are changing from old methods such as printing stamps and manual records to an intelligent direction. Oil pipes with electronic tags are currently the mainstream solution. In order to prevent the electronic tag from being damaged by environmental factors such as friction and vibration during the oil pipe operation, the electronic tag needs to be embedded and packaged in the pipe wall, that is, the electronic oil pipe. Considering the size, wall thickness and tensile strength, the collar is a reasonable place for the electronic tag to be installed. [0003] The coupling is a single part that connects two oil pipes. It is threaded with the oil pipe. During operation,...

Problems solved by technology

However, for the electronic tubing currently being promoted on the market, the slotting positions of the couplings are different, and the slotting parameters are only obtained through continuous trials, which is not only time-consuming and labor-intensive, but also difficult to meet the conditions of different well conditions in different regions requirements, it is difficult to dispel market doubts
