摘　　要：利用B&K声压测试系统对新型低压脉冲射流调制器样机振动特性进行试验,系统研究了调制器工作特性随钻头压降、钻井液流量及定子倾角等参数变化的规律。结果表明:调制器振动频率随钻井液流量的增加而增大,随钻头压降上升而基本不变,随定子流道倾角的增大而增高。为全尺寸定转子式脉冲调制器的设计和应用提供依据。The performance of the modulator is experimentally studied with the B K sound-pressure test system.The dynamic characteristics of a newly designed low-pressure pulses modulator are studied according to its structural parameters and the working hydraulic parameters such as the stator＇s obliquity,pressure drop and fluid volume and so on.The result of the experiment show that frequency of the modulator increase with increase of the fluid volume and the stator＇s obliquity,which provide an effective assistant way in the further study and application of the full-size rotor/stator low-pressure pulse jet modulator.
