摘　　要：为了解决当前常规随钻扩眼器在实际应用中的问题,设计了一种基于射频识别控制技术的随钻扩眼器,实现了控制命令的井下无线传输和接收,并通过液压执行机构控制扩眼刀翼动作,实现井下扩眼操作。工具设计过程中,在射频识别天线外部安装铁氧体屏蔽环,解决了井下金属涡流对天线磁场强度的削弱问题,保证了井下射频识别通讯系统对控制命令的可靠接收;通过理论计算和仿真分析确定了液压执行系统最大承压能力,为电磁阀优选和液压回路承压设计提供了理论依据,保证扩眼刀翼的可靠锁止。设计的RFID随钻扩眼器成功进行了4口井的现场扩眼作业,验证了工具的工作可靠性和稳定性。In order to solve the problems of conventional reamer while drilling in practical application,the paper designed a kind of reamer while drilling based on RFID technology.The commands are wireless transmitted and received by RFID commutation system,and hydraulic executive system control the action of reamer blade to realize the downhole reaming operation.In the process of tool design,by installing ferrite shielding ring outside the RFID antenna,the problem of weakening the magnetic field intensity of the antenna caused by downhole metal eddy current is solved,it ensures the reliable reception of commands by the downhole RFID control system.The maximum pressure of hydraulic executive system is determined by theoretical calculation and AMESim simulation,which provides a theoretical basis for optimum selection of solenoid valve and pressure design of hydraulic circuit,so that the reamer blade can be reliably locked.The designed RFID reamer while drilling has been successfully used in 4 wells,which verifies the reliability and stability of the tool.
