摘要： Acoustic transducers configured with integrated electronics technology are adapted to digitize signal data close to the transducer. The transducers are packaged with a reduced number of elements and sealed for exposure to harsh environments, without oil compensation. A transducer assembly includes a frame, an acoustic transducer element disposed on the frame, and an electronics module disposed on the frame and linked to the acoustic transducer element. The pressure and temperature tolerant electronics module is adapted to process a signal associated with the transducer element.

摘要： Acoustic transducers configured with transducer elements disposed on an arch or arcuate shaped member adapted to fit in juxtaposition around a tubular. The arcuate shaped member is adapted with conductors to provide a voltage to the transducer elements. One embodiment uses a metallic arcuate shaped member. Embodiments implemented as sources are used to excite borehole acoustic modes. Some embodiments provide phased array acoustic energy excitation/signal reception. The transducers are covered with a sealer in a liquid-free configuration and shields are used to protect the transducers.

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： Methods and apparatus to control a formation testing operation based on a mudcake leakage are disclosed. A disclosed example method for use with a downhole tool disposed in a wellbore comprises measuring a property of a mudcake layer at a first location in a wellbore, determining a value representative of an estimated leakage through the mudcake layer based on the property, and determining, based on the value, whether to continue a formation testing operation.
