摘要： A method and apparatus for detecting a kick in a wellbore using acoustic transducers. In one embodiment, a system for detecting a kick in a wellbore includes a drill string having a plurality of sections of drill pipes and a plurality of kick detection subs disposed between the sections of drill pipes. Each of the kick detection subs includes an acoustic transducer and kick detection circuitry coupled to the acoustic transducer. The kick detection circuitry is configured to detect gas bubbles in the wellbore based on acoustic signals received by the acoustic transducer. The kick detection circuitry is also configured to determine whether a kick is present in the wellbore based on the detected gas bubbles. The kick detection circuitry is further configured to transmit information indicating whether a kick is present to the surface.

摘要： A method for in-situ calibrating acoustic receivers while the tool is in an open or cased borehole or during a logging run in a borehole. The method and system facilitate calibrating the acoustic receivers while they are mounted to a downhole acoustic tool. Calibrating the acoustic receivers in situ provides more accurate results than previously available. The method and system provide separate compensation factors for the acoustic receivers at different frequencies and for different transmission sources. The separate compensation factors facilitate more accurate signal acquisition over a wider range of conditions.
