摘要: 为实现压裂级数不受限制、各级压裂滑套结构一致且可以智能控制的目标,设计出了一种基于RFID(射频识别技术)的滑套控制系统。当投放的RFID标签球通过压裂管道时,经过标签球里内置天线与读写器天线耦合,将存储的数据向井下发送。读写器接收载波信号后根据不同的设置发送指令信号给电控部分。电控部分驱动空心轴电机转动,空心轴电机部分通过霍尔信号控制电机精确换向,从而实现智能调节滑套的开度和启闭。通过搭建实验台架进行实验,验证了系统的可靠性。

Abstract: In order to achieve unrestricted fracturing stages and consistent and intelligently controllable sliding sleeves in all stages, a sliding sleeve control system is designed on the basis of radio frequency identifcation (RFID) technology. When the RFID tag ball passes through the fracturing string, the stored data is sent to the downhole through the coupling between in-built antenna and reader antenna. The reader sends a command signal to the electronic control unit according to different settings after receiving the carrier signal. The electronic control unit drives the hollow-shaft motor to rotate, and the hollow-shaft motor realizes accurate commutation through the Hall signal, so that the openness and opening/closing of sliding sleeve is intelligently adjusted. An experiment was conducted on the bench to verify the reliability of the system.

Key words: antenna, hollow-shaft motor, openness, radio frequency identifcation (RFID), sliding sleeve
