摘要

为了实现多级滑套压裂工具全通径、无级数限制和智能操控,研究了无线射频识别(RFID)技术驱动滑套的工作原理和施工工艺。RFID滑套由胶囊标签、天线单元、控制单元、执行单元、动作单元和连接单元等部分构成。胶囊标签携带信息码通过RFID滑套,激活控制单元接收信息码,当信息匹配时,控制单元输出控制命令,启动执行单元动作,实现滑套的打开或关闭动作。通过技术调研,掌握了RFID滑套的工作原理和施工工艺,明确了RFID滑套研制的关键技术难点,为无线射频识别技术在多级滑套压裂工具中的应用提供了技术支持。

Abstract

In order to realize full opening,unlimited fracturing stages and intelligent control of the fracturing sliding sleeve,the working principle and process of radio frequency identification(RFID) driven fracturing sliding sleeve have been studied.RFID fracturing sliding sleeve consists of capsule pins,an antenna unit,a control unit,an execution unit,action units,and the connecting unit.Capsule pins that carry the information codes through RFID fracturing sliding sleeve will activate the control unit that receives the information codes.If codes match,the control unit will send commands to start the action unit to open or close the fracturing sliding sleeve.Through technical research,we have gotten a clear understanding of the basic working principle and operation process of RFID fracturing sliding sleeve,the technical difficulties in RFID sliding sleeve development and provide technical support for the developing of RFID sliding sleeve in China.
