    摘要： The present invention is directed to a device which simply and efficiently compensates for changes in the volume of a fluid trapped in a fluid-filled cavity between two relatively immovable housings and an elastomeric seal ring. The present invention is particularly useful in an acoustic transducer pad assembly designed for installation on logging tools used in deep boreholes in the oil and gas industry where high temperatures and pressures are experienced at downhole locations. In a presently preferred embodiment, the device comprises a transducer unit housing fixedly secured to a metal wear pad housing with an elastomeric seal disposed therebetween to define a fluid-filled cavity between adjacent portions of the housings and the seal. The seal is disposed in a groove of sufficient size to permit the required lateral expansion and contraction by deformation or extrusion of the seal in order to compensate for the expected changes in the volume of the fluid-filled cavity.

    摘要： The present invention is directed to an apparatus useful in downhole logging tools used in the oil and gas industry. The present invention is particularly directed to an acoustic logging tool including improved, articulated transducer pad assemblies for providing improved transducer contact with the wall of a borehole or the inside wall of casing cemented in the borehole. The apparatus of the present invention provides a plurality of articulated transducer pad assemblies disposed about the circumference of an acoustic logging tool in a plurality of separately movable and adjustable groups. These assemblies each include a plurality of articulated joints permitting limited independent movement of each assembly. The assemblies are spring biased at each end into a deployed configuration to maintain good contact with the wall of the borehole or casing. A drive motor overcomes the biasing springs to retract the assemblies to provide a compact tool for tripping to the location of interest within the borehole.

    摘要： A vertical seismic profiling system includes seismic receivers for placement on a drillstring and surface seismic sources. One-way checkshot data may thus be measured without tripping the drillstring. A downhole acoustic tool measures the local interval transit time of the formation, and improves the detection of targets ahead of the drill bit. The local interval transit time may be applied to the time of travel from reflections in front of the bit to establish distance to the bit. The down-going wavetrain may be deconvolved with the total up-going wavetrain to extract the nearest reflector and the relative acoustic impedance at the reflector. A synthetic seismogram may also be created based on reflection depth data and corrected with checkshot data.

    摘要： A process and apparatus for treating a wellbore, comprising subjecting a substantially same portion of the wellbore to vibratory waves produced by a plurality of vibratory wave generators. The vibratory waves may have about the same frequency or a plurality of frequencies, and the frequencies may partially overlap, not overlap, or be modulated across a range. Additionally, the frequencies may be modulated in an oval, hoop, and flexural modes. The vibratory waves may be produced by firing the vibratory wave generators simultaneously or in sequence. Combinations of a vibrating pipe, piston pulser, or valve may be used as vibratory wave generators. In a preferred embodiment, the thickness and change of thickness of a mudcake on the interior surface of a wellbore are measured to evaluate the effectiveness of the wellbore treatment.

    摘要： Disclosed is a sonic well tool for performing acoustic investigations of subsurface geological formations penetrated by a borehole. The well tool generally includes a longitudinally extending body for positioning in said borehole. The tool also includes a transmitter supported by the body for transmitting acoustic energy, and a receiver supported by the body for receiving acoustic energy. Finally, the tool includes an acoustic attenuation section positioned on the body between the transmitter and the receiver. This section includes one or more cavities defined by the body, inertial mass members positioned inside the cavities in a suitable manner to form a gap between the wall of the cavity and the inertial mass members, and an acoustical attenuation fluid in the gap. The method for attenuating sonic waves generally includes transmitting a sonic wave from the transmitter to the tool, passing the sonic wave through the acoustic attenuation section, and receiving attenuated wave at the receivers.
