摘　　要：在随钻石油测井仪器中,涡轮发电机必须经过严格的可靠性测试才能应用到井下测井仪器中。常规的水循环测试方法存在测试设备体积庞大、试验成本高、费时费力的问题。设计了涡轮发电机在线测试系统。采用电动机对拖发电机的方式使涡轮发电机转动。通过改变电动机的转速,便捷地模拟出井下不同成分和密度的泥浆流动工况环境。输出的电力整流滤波后进入可调的电子负载模块,从而测量出发电机的发电能力,以完成涡轮发电机本体输出能力测试及可靠性测试。试验结果证明,该系统操作简单、方便实用,降低了仪器的开发周期和开发成本。该系统已成功应用于随钻仪器的研制及测试,对今后涡轮发电机本体的设计与改进有指导意义。In oil logging instruments with drilling,turbine generators must undergo rigorous reliability testing before they can be applied to downhole logging instruments.Conventional water cycle test method has the problems of the bulky test equipment,high test cost and high time-consuming and laborious.A turbine generator on-line test system is designed.A motor-to-drag generator is used to rotate the turbine generator.By changing the rotational speed of the motor,the downhole mud flow condition environment with different compositions and densities is conveniently simulated.The output power is rectified and filtered into the adjustable electronic load module,to measure the generator’s power generation capacity and complete the turbine generator body output capacity test and reliability test.Test results prove that the system is simple to operate,convenient and practical,and reduces the development cycle and development cost of the instrument.The system has been successfully applied to the development and testing of drilling instruments,which is of guiding significance to the design and improvement of the turbine generator body in the future.
