    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.

    摘要： Apparatus is provided for assisting a subsurface well logging instrument, perforating tool or wireline service tool in tubing or casing re-entry in deviated boreholes. The apparatus includes a body member, composed of two conjugated halves, rotatably mounted on the well logging cable immediately above the well logging instrument. A pair of wheels are rotatably mounted to the uphole facing portion of the apparatus. These wheel members provide a lifting action upon tubing or casing contact to thereby lift the logging cable off the casing and prevent the logging instrument from engaging in jammed contact with the exposed end of the tubing or casing.

    摘要： An axially extended downhole seismic source is disclosed. In one embodiment, the seismic source includes multiple pressure storage chambers, each having an inlet valve and an outlet valve. The inlet valve is coupled between the pressure storage chamber and the interior of the drill string, and the outlet valve is similarly coupled between the pressure storage chamber and the annular space around the drill string. A compressible fluid may be provided in the pressure storage chambers, and pistons may be positioned to contact the compressible fluid. For each pressure storage chamber, an inlet piston contacts the compressible fluid and fluid inside the drill string, while an outlet piston contacts the compressible fluid and fluid in the annular space around the drill string. When the outlet valve is closed, the inlet valve can be opened to allow pressure inside the drill string to compress the compressible fluid inside the pressure storage chamber. Subsequently closing the inlet valve and opening the outlet valve causes fluid to be ejected into the annular space, thereby generating seismic waves. The use of multiple pressure storage chambers allows the pressure front from the seismic source to be extended axially to advantageously increase the fraction of seismic energy transmitted into the formation while preventing damage to the formation.

    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.
