A slotting parameter extraction method for oil pipe electronic tag implantation

Abstract

The invention provides a slotting parameter extraction method for oil pipe electronic tag implantation. The slotting parameter extraction method comprises the following steps that the length A, the width B and the height G of an electronic tag are obtained; ANSYS simulation analysis is carried out to obtain the width W2 of the allowable slotting of the stress state of the tubing coupling, the depth H2 of the allowable slotting and the length L2 of the allowable slotting; The value ranges of the length L, the width W and the depth H of the electronic tag mounting groove are obtained; with the value range of the width W and the depth H of the electronic tag mounting groove fitting a functional relationship between the coupling stress and the stress function to obtain the yield strength of the material for the tubing coupling and the length L of the slot; fitting a function relationship between the radio frequency signal strength and the radio frequency signal strength function to obtaina second association relationship between the signal source strength required for receiving the radio frequency signal within a certain range and the length L, width W and depth H of the slot; And solving the first association relationship and the second association relationship to obtain accurate values of the length L, the width W and the depth H of the slot.

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
