Application of Radio Frequency Identification in Multistage Fracturing Sleeve Tools

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.
