摘　　要：根据石油工业工程需要,研究开发了一套用于井下流量、温度、压力监测的无线数据交换系统,系统通过无线方式从井下提取已采集的数据并实时传送给地面监测系统.在该系统中,天线作为井下无线数据交换的核心部分,起着决定性的作用.文中针对这一应用介绍了天线的设计方法、工作方式及参数计算举例,给出了经过优化设计后的天线各参数值,实验结果验证了其有效性.According to the requirements of oil industry engineering, a wireless data transfer system is developed, which is used in deep oil well or water injected well for temperature, flux and pressure monitoring. Because of the particular working condition of deep oil well and water injected well, the antenna design is more complicated than the common microwave antenna worked on ground. In this paper, the theory of antenna designing is introduced in details at first. Then the operation mode and parameter calculation method of the antenna are given via examples. Finally, optimized parameter values are obtained by various antenna adjustments. Experiments show the correctness and effectiveness.
