Research on Mud Flow Rate Measurement Method Based on Continuous Doppler Ultrasonic Wave
In deep-water drilling processes, the flow rate of drilling mud inside an annular pipe is significant judgment data for early kick detection. On the basis of the continuous-wave Doppler ultrasound, this paper proposes a new detection method of nonoriented continuous-wave Doppler ultrasound. The meth...
