摘　　要：介绍了由井下PTCR热散式流速传感器和井口单片机数据采集系统组成的油井注入液体流速检测系统。解决了井下高粘度。The flow velocity detecting system of oil well injected liquid is introduced. The system is composed of the PTCR heat dissipative flow velocity transducer in the pit and the single chip computer based data acquisition system at the wellhead. The system solved the problem of measurement for flow velocity of fluid with high viscosity and low flow rate.
