Problems solved by technology

The main variable structural parameters of the flange are thickness and inner diameter. At present, the wellhead conformal flange adopts the scheme of thickness as thick as possible and inner diameter as small as possible to ensure safety. Such a flange is too heavy, causing serious damage to the field application great inconvenience
How to design a conformal protective flange for wellhead electronic tag readers considering both protective performance and weight has not yet been well resolved

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] as attached figure 1 and 2 As shown in the figure, the design object of the present invention is a conformal protective flange 2 for installing a wellhead electronic label reader. The structure of the flange is a hollow circular ring. The bottom surface of the conformal protective flange 2 is processed with electronic Label reader interface installation slot 1, which is a rectangular slot.

[0029] The invention provides a method for extracting structural parameters of a protective flange, and the specific implementation steps of the method are as follows:

[0030] Step 1, the stress analysis of the flange can be concluded that there are three factors that affect the stress of the flange during the pressure-bearing process: load-bearing G, flange thickness H, flange inner diameter D 1 ; For safety reasons, the stress generated after the flange...

Abstract

The invention discloses a protective flange plate structure parameter extraction method, and belongs to the technical field of flange plate structure design. The method comprises the specific implementation steps of firstly determining influence factors, influencing a stress value, of a flange plate in a pressure-bearing process and a mutual relation among the influence factors; secondly determining a reference bearing weight and a corresponding reference stress function; thirdly determining a reference stress range meeting a condition; and finally according to the reference stress range, determining flange plate inner diameter and thickness meeting the requirements. Through a mutual relation of a flange plate bearing weight, material yield strength and the flange plate inner diameter andthickness, a scientific design method is provided for determining the flange plate inner diameter and thickness; the conformal protective flange plate meets protective performance required for protecting a wellhead radio-frequency identification electronic tag reader; the weight can be reduced; and field application and popularization are facilitated.

Description

technical field [0001] The invention relates to a method for extracting structural parameters of a flange, in particular to a method for extracting structural parameters of a conformal protective flange of a wellhead electronic label reader during downhole operations in the petroleum industry, and belongs to the technical field of flange structure design. . Background technique [0002] In the production of oil and gas operations, oil pipe marking and usage status records are changing from old methods such as stamping and manual recording to intelligent ones. Oil pipes with electronic labels are the current mainstream solution. Electronic tags are mainly identified by hand-held and fixed RFID electronic tag readers. In order to avoid the tens of tons of elevators and tubing from damaging the electronic tag reader fixed at the wellhead during the process of running the tubing downhole, it is necessary to install a conformal protective flange matching the reader at the wellh...
