摘要
基于射频识别技术的无干预完井系统无需钢丝绳、电缆或连续管等人机干预作业便可灵活地对完井作业过程实施远程控制和操作。射频识别技术由电子标签、阅读器、数据交换器和控制系统组成,其控制系统中的液压动力单元可自给电能和液压能,并与带有液压控制线的配套工具相连;可将液压循环阀当作液动滑套使用,采用无弹性体的金属对金属密封技术。性能测试和应用结果表明,系统的各项指标完全满足ISO标准和现场使用要求,液压循环阀可适应温度135℃、压力34.5 MPa的恶劣工作环境。
The intervention-less completion system based on RFID allows for remote control and operating dur- ing completion operation without slickline, wireline or coiled tubing intervention. RFID technology consists of elec- tronic tags, reader, data exchanger and control system. The hydraulic power unit in the control system is connected with the supporting tool with hydraulic control line, and could provide electric energy and hydraulic power. The hy- draulic circulating valve is metal-to-metal sealed and serves as hydraulic sleeve. Performance tests and application results show that the index of the system could fully meet ISO standards and the onsite application requirements. The hydraulic circulating valve could withstand challenging working conditions with the temperature of 135℃ and pres- sure of 34. 5 MPa.
