The present invention discloses systems and methods for calculating flow rates. The system includes at least two ultrasonic sensors, an ultrasonic transceiver device and a signal processing device. At least two ultrasonic sensors are arranged on the pipe for fluid to flow through, the at least two ultrasonic sensors have different ultrasonic beam paths, and the ultrasonic beam paths of the at least two ultrasonic sensors have overlapping regions. The ultrasonic transceiving device is used to excite at least two ultrasonic sensors, to transmit one or more ultrasonic signals to the pipeline through one or more of the at least two ultrasonic sensors, and to receive ultrasonic signals through at least two ultrasonic sensors. The signal processing device is used for processing the received ultrasonic signal, so as to accurately calculate the flow velocity of the fluid. The system and method of the invention can be applied in many fields and have high application value.
Description
technical field [0001] The present invention generally relates to systems and methods for calculating flow rates, and more particularly to a system and method for calculating flow rates during drilling. Background technique [0002] When drilling, the rotatable drill bit is set on the drill pipe, and the offshore platform controls the drill bit through the drill pipe, and the drill pipe drives the drill bit to rotate, thereby drilling the wellbore from the seabed. During this time, the drilling fluid from the fluid tank provided on the offshore platform passes through the drill pipe to the drill bit and then returns to the fluid tank through the annular space formed between the drill pipe and the riser. The drilling fluid maintains a certain hydrostatic pressure to balance the pressure of the fluid from the wellbore and cool the drill bit. In addition, drilling fluid is mixed with materials produced during wellbore formation to return and carry them to the surface for dispo...
