摘要： Methods for processing ultrasonic signal data to evaluate subsurface properties and tool orientation. Acoustic signals are transmitted into a plurality of azimuthal borehole positions. Formation echo signal transit time distributions are then determined in a plurality of azimuthal sectors for the acoustic signals. Front face echo signal transit times are also measured and farther-mode and closer-mode transit times are determined for the distribution of formation echo signals. Farther and closer tool standoffs are determined for the azimuthal sectors and a borehole diameter is determined from a summation including standoffs in opposing sectors. The standoffs are also used to determine a preferential tool position.

摘要： A Measurement-while-Drilling method and apparatus for obtaining information about a formation uses sensors on substantially non-rotating pads attached to a rotating housing that is part of the drilling assembly. The pads make contact with the formation. The sensors may be density, NMR, resistivity, sonic or electromagnetic. The NMR sensors may use a static magnetic field that can be either radial or longitudinal in direction. The resistivity sensors may involve direct measurement of leakage current or may rely on induction methods. The sonic sensors may be three component transmitters and/or receivers for determining compressional and shear velocities of the formation and may also be used to image the formation in a VSP or a reverse VSP. In an alternate arrangement, the sensors rotate with the drill bit. A downhole microprocessor analyzes the data to improve signal-to-noise ratio and to reduce redundancy in the acquired data. Depth information may be telemetered from an uphole controller to facilitate the process. The downhole processor has adequate memory to store the processed data for subsequent retrieval when the well is being tripped. Alternatively, a subset of the stored data may be telemetered uphole during the drilling process.

摘要： An apparatus and method for using swept frequency energy to inspect a casing or other body is disclosed. A transducer (75) transmits a swept frequency pulse at a casing and receives the reflection resulting from the pulse's impact against the casing. The reflected energy is translated to a reflection signal and analyzed by a signal processor having an envelope detector (240) which translates the reflection signal into an envelope signal. A microprocessor (260) located within the signal processor analyzes the envelope signal to compute data such as the thickness of the casing and the quality of the cement bond holding the casing.

摘要： A method and apparatus for measuring formation characteristics as a function of angular distance segments about the borehole is disclosed. The measurement apparatus includes a logging while drilling tool which turns in the borehole while drilling. Such characteristics as bulk density, photoelectric effect (PEF), neutron porosity and ultrasonic standoff are all measured as a function of such angular distance segments where one of such segments is defined to include that portion of a "down" or earth's gravity vector which is in a radial cross sectional plane of the tool. The measurement is accomplished with either a generally cylindrical tool which generally touches a down or bottom portion of the borehole while the tool rotates in an inclined borehole or with a tool centered by stabilizer blades in the borehole.

摘要： An apparatus and a method are provided for measuring the caliper of a borehole, and the standoff of a drilling tool from the walls of a borehole during a drilling operation. The apparatus includes three or more sensors, such as acoustic transducers arranged circumferentially around a downhole tool or drill collar. The transducers transmit ultrasonic signals to the borehole wall through the drilling fluid surrounding the drillstring and receive reflected signals back from the wall. Travel times for these signals are used to calculate standoff data for each transducer. The standoff measurements may be used to calculate the caliper of the borehole, the eccentricity of the tool in the borehole, and the angle of eccentricity with respect to the transducer position. The eccentricity and angle computations may be used to detect unusual movements of the drillstring in the borehole, such as sticking, banging, and whirling.

摘要： An MWD measuring apparatus and technique using a single transducer mounted on an MWD drill collar near a tubular member, such as an upset or stabilizer blade. The minimum stand-off is the radial difference between the MWD drill collar and the tubular member when the drillstring is side-walled against the borehole wall. Control apparatus connected to the transducer determines elapsed time for each pulse transmitted towards and reflected from the borehole wall. A plurality of round-trip transit time (RTT) values are measured and the results statistically analyzed to identify and verify the RTT.sub.min value corresponding to the minimum stand-off distance. The RTT values may be analyzed directly or using histogram techniques. Once determined, the sound speed of the drilling fluid is calculated as twice the radial difference between the MWD collar and stabilizer blade or upset divided by the RTT.sub.min value. Also, the sound speed is used to calculate the stand-off distance corresponding to other RTT values, if desired.
