摘要： A downhole acoustic measurement tool includes at least one transmitter longitudinally spaced apart from a non-uniformly spaced longitudinal array of acoustic receivers. The array has a non-uniform spacing such that a first spacing between a first pair of consecutive acoustic receivers in the array is not equal to a second spacing between a second pair of consecutive acoustic receivers in the array. Non-uniform spacing of the receivers in the array reduces aliasing when the received waveforms are processed, for example, to obtain semblance data.

摘要： A microresistivity logging tool includes a dual function electrode deployed between a guard electrode and a return electrode. A drive circuit enables the electrical potential of the dual function electrode to be independently controlled so as to control a depth of investigation of a microresistivity measurement.

摘要： Methods for making calibrated microresistivity logging measurements in nonconductive drilling fluid are disclosed. A calibrated measurement parameter (e.g., a calibrated electrical impedance or a calibrated potential difference) is obtained and further utilized to compute a formation resistivity. The methods tend to be particularly well suited for drilling applications in which the borehole environment is highly resistive (i.e., boreholes in which both the drilling fluid and the formation have a high resistivity).

摘要： A downhole measurement tool includes at least one non-planar antenna configured for transmitting and/or receiving electromagnetic radiation. The non-planar antenna includes at least one non-planar loop of antenna wire deployed about a tool body. In one exemplary embodiment, the non-planar antenna may be thought of as being bi-planar in that it includes first and second sections defining first and second intercepting geometric planes. In another exemplary embodiment, the axial separation between the non-planar loop of antenna wire and a circular centerline of the antenna varies substantially sinusoidally with respect to an azimuth angle about the circumference of the tool. Exemplary non-planar antennae in accordance with the invention may be advantageously configured to transceive substantially pure x-, y-, and z-mode radiation.

摘要： An acoustic logging while drilling tool includes an acoustic transmitter and a linear array of acoustic receivers. At least one of the transmitter and the linear array of receivers is deployed on a blade having an outer diameter greater than that of the tool body. In preferred embodiments the transmitter and linear array are each deployed on a distinct blade. Deployment of the transmitter and/or the receivers on a blade reduces the standoff distance to the borehole wall which tends to improve the signal strength of received guided waves without an increase in transmitter power or receiver sensitivity.

摘要： A logging while drilling tool includes a directional resistivity antenna and an antenna shield having. The shield has at least one slot having at least one electrically open end formed therein. The antenna shield may include a base portion and a plurality of spaced apart fingers extending away from the base portion such that the finger ends are electrically isolated from the tool body and from one another. The antenna shield may alternatively include a plurality of spaced apart plates that are electrically isolated from the tool body and from one another. These antenna shields have been found to provide suitable physical protection for sensitive antenna components while at the same time being substantially transparent to both z-mode and x-mode electromagnetic waves.
