摘要： A transducer configuration disposed within a wellbore sonde for acoustically imaging a target region behind an acoustically reflective layer includes a transmitting transducer for producing a transmitted acoustic beamspread pattern defined by a insonified zone having a width approximately equal to a width of the transmitting transducer and a transmitting main lobe beyond the transmitting collimated zone. The transducer configuration also includes a receiving transducer disposed adjacent the transmitting transducer. The receiving transducer includes an acoustic signal reception pattern defined by a insonified zone having a width approximately equal to a width of the receiving transducer and a receiving main lobe beyond the receiving insonified zone. A beamspread angle defines an amplitude contour forming an outer periphery of the transmitting and receiving main lobes. Intersection of the transmitting and receiving main lobes behind but not within an acoustically reflective layer allows the transducer configuration to null reverberation energy from the acoustically reflective material and enhance acoustic energy received from the less reflective material disposed behind the highly reflective material.

摘要： A system for acoustically imaging a target region behind an acoustically reflective layer includes a transducer configuration for acquiring acoustic image data from the reflective layer and target region, wherein the reflective layer and target region are divided into voxels circumferentially disposed about a central point. The system includes a mechanism for processing the data comprising a transmitting transducer for transmitting a first acoustic pulse, a receiving transducer for detecting a first arrival of a first acoustic reflection signal associated with the first acoustic pulse, and a mechanism for suppressing multiple reflected signals from the acoustic reflection signal associated with the first acoustic pulse, wherein the suppressing mechanism facilitates the acquisition of image data from the target region. The system may also include a mechanism which filters and compresses acoustic data downhole, transmits data uphole and which reassembles data uphole for conversion into an image on standard computer display equipment.

摘要： A transducer configuration for use in acoustically imaging a target region behind an acoustically reflective layer includes a sonde having a geometrical center and constructed and arranged to support a plurality of transducers. The system includes a first transducer disposed within the sonde at a first distance from the geometrical center for generating a first acoustic pulse and for receiving a first acoustic signal. The acoustic signal comprises a first reflection from the reflective surface, a first set of fluid multiples arising from reflections between the reflective layer and a surface of the first transducer, and a first signal associated with the target area. The system also includes a second transducer disposed within the sonde at a second distance from the geometrical center for generating a second acoustic pulse and for receiving a second acoustic signal. The second acoustic comprises a second reflection from the reflective surface, a second set of fluid multiples arising from reflections between the reflective layer and a surface of the second transducer and a second signal associated with the target area. A mechanism for receiving and processing signals received by the first and second transducers at time intervals which occur between receipt of the first and second sets of fluid multiples, respectively, wherein signal values at time intervals between receipt of fluid multiples provide acoustic waveforms associated with the target region. Each target region, therefore, has a time interval on at least one of the two waveforms which is free of fluid multiples.

摘要： A sonic or acoustic tool is disclosed which includes a transmitter with reduced transmitter spawned noise. The transmitters are either monopole or dipole depending on the orientation of ports in a chamber divided by a piston driven by an actuator. The transmitter size is limited only by the diameter of the tools itself because the transmitters are oriented within the tool parallel to the axis of the tool.

摘要： Disclosed herein are various embodiments of power conversion systems and methods employing synchronous multi-phase AC-to-DC conversion. In one embodiment, a power converter comprises a transistor bridge and a switching controller that operates the transistor bridge in response to AC voltage threshold crossings. The switching controller may include a period counter to measure times between threshold crossings, and a delay counter to trigger a delayed state transition for the transistor bridge. One disclosed method embodiment comprises: receiving multiple phased alternating voltages; comparing each phased alternating voltage to a threshold; determining a period associated with voltage threshold crossings; triggering state transitions at some fraction of the period after each threshold crossing; and placing a transistor bridge into a configuration associated with a current state. For each state, the transistor bridge configuration is designed to couple phased alternating voltages to two output terminals in a sequence that produces a non-alternating voltage difference.
