Abstract: A kick detection system for drilling a well including an ultrasonic module for transmitting signals to a returning drilling fluid from the well, and receiving corresponding backscatter signals; and a process apparatus for obtaining a flow characteristic of the returning drilling fluid based on the backscatter signals, and detecting a kick based on the flow characteristic of the returning drilling fluid and drilling related data. A well drilling system including a drilling string for guiding a drilling bit and a drilling fluid to a well; a conduit defining a channel for accommodating the drilling string and a returning drilling fluid from the well; and the kick detection system. A kick detection method is also described.

Abstract: A method of measuring a flow rate of a fluid flowing in a space between an outer conduit and an inner element in the outer conduit is provided. Ultrasonic waves are transmitted and received through the space between multiple pairs of ultrasonic transducers along multiple propagation paths, respectively. A mean line velocity of the fluid is calculated based on data from each pair of ultrasonic transducers. As such, multiple mean line velocities across the space are obtained. The flow rate of the fluid is calculated based on the multiple mean line velocities.

Abstract: An ultrasonic flow meter system includes a conduit defining a channel, at least one pair of first transducers, at least one second transducer, and a processor. The pair of first transducers is mounted on the conduit and includes a transmitting transducer and a receiving transducer for generating a first responsive signal. The transmitting transducer and the receiving transducer are arranged on a chordal path. The second transducer is mounted on the conduit for generating a second responsive signal. The processor is configured to receive the first responsive signal and the second responsive signal, select one responsive signal according to a relationship of the first responsive signal and noise thereof and a relationship of the second responsive signal and noise thereof, and determine a flow rate of a flow medium according to the selected responsive signal. A method for measuring the flow rate of the fluid medium is also provided.
