摘　　要：为了实现注水井的测调一体化以及智能注水,在注入流道直径小于40mm的情况下,根据发电机的设计原则,计算了尺寸和参数。利用COMSOL软件建立了发电机模型,并对发电机的电磁场进行了仿真,得到了发电机的磁通分布。加工实物后进行实验,实验数据与期望结果基本一致,验证了发电机定转子排布与尺寸的合理性。当转速为600 r/min时,可稳定输出10 W以上功率,可见本发电机能满足井下脉冲发射器与电池的供电要求。In order to realize the integration of measurement and adjustment of water injection well and intelligent water injection,the size and parameters of injection channel are calculated according to the design principle of generator when the injection channel diameter is less than 40 mm.The generator model is established by COMSOL software,and the electromagnetic field of the generator is simulated.The magnetic flux distribution of the generator is obtained.The experimental data are basically consistent with the expected results,which verifies the rationality of the generator stator and rotor arrangement and size.When the speed is 600r/min,the generator can stably output 10W power.It can be seen that the generator can meet the power supply requirements of downhole pulse transmitter and battery.
