Selection of Diameter of Spherical Tagin Fracturing Process which Use Radio Frequency Identification Technology
Shengtong Yuan | Jian Chen
Abstract: In recent years, multi-stage fracturing technology of horizontal well with intelligent sliding sleeve based on radio frequency identification technology is gradually applied to the field of horizontal well fracturing. The selection of diameter of spherical tag become a new problem because the new process need tags have slow speed when pass through the smart sleeve and these spherical tags could not come into being blocked by themselves when fracturing fluid backflow. This paper took some researches of diameter selection of the spherical tag through these two aspects. The numerical simulation and mechanics analysis results show that, the smaller diameter of RFID tag, the higher recognition of signal within a certain range. However the diameter of RFID tag should not be too small considering the blocking in fracturing fluid backflow process. Spherical tag moving in the tubing which diameter is 76mm carried by fracturing fluid, the diameter of spherical tag select 48mm is suitable.
