摘要： The disclosure relates to methods and apparatus for determining the velocity of an ultrasound pulse in drilling fluids in downhole environments. A method for determining a velocity of ultrasound propagation in a drilling fluid in a downhole environment includes emitting an ultrasound pulse into the drilling fluid in a borehole using a first ultrasound transducer (37); detecting the ultrasound pulse after the ultrasound pulse has traveled a distance (d); determining a travel time (t) required for the ultrasound pulse to travel the distance (d); and determining the velocity of ultrasound propagation from the known distance (d) and the travel time (t). An apparatus for determining a velocity of ultrasound propagation in a drilling fluid in a downhole environment includes a first ultrasound transducer (37) disposed on a tool; and a circuitry (82) for controlling a timing of an ultrasound pulse transmitted by the first ultrasound transducer (37) and for measuring a time lapse between ultrasound transmission and detection after the ultrasound pulse has traveled a distance (d).

摘要： Acoustic communication apparatus for use with downhole tools are described. An example acoustic communication apparatus for use in a wellbore includes a first acoustic transducer to generate first acoustic signals. The first acoustic transducer is mounted in an interior of a first drill collar to transmit the first acoustic signals via at least a portion of a body of a drillstring or a mud channel within the drillstring to a second drill collar. Additionally, the example acoustic communication apparatus includes a first receiver mounted to the first drill collar to receive second acoustic signals transmitted from the second drill collar.
