Abstract: In some embodiments, an apparatus and a system, as well as a method and an article, may include exciting a plurality of signal source pairs having a substantially equal and non-zero acoustic signature amplitude difference in a frequency domain to provide acoustic signal data, and acquiring the acoustic signal data along a selected azimuth. The plurality of signal source pairs may comprise acoustic bender plates, perhaps included in the outer wall of a downhole tool.

Abstract: One or more acoustic transducers are used to measure ultrasonic velocities in the mud in the interior channel of a drill collar. Corrections may be applied for temperature and/or fine grain drill cuttings to get the ultrasonic velocity in the annulus between the drill collar and the borehole wall. The latter velocity may be used for caliper measurements and for correcting measurements made by formation evaluation sensors.
Abstract translation: 使用一个或多个声换能器来测量钻铤的内部通道中的泥浆中的超声波速度。 校正可以应用于温度和/或细粒钻屑，以获得在钻铤和钻孔壁之间的环空中的超声波速度。 后者的速度可用于卡尺测量和用于校正由地层评估传感器进行的测量。

Abstract: A downhole acoustic logging tool is used for generating a guided borehole wave that propagates into the formation as a body wave, reflects from an interface and is converted back into a guided borehole wave. Guided borehole waves resulting from reflection of the body wave are used to image a reflector.
Abstract translation: 井下声波测井工具用于产生作为体波传播到地层中的导向井眼波，从界面反射并转换成导向的井眼波。 使用由身体波反射引起的导向井眼用于对反射镜进行成像。

Abstract: Acoustic measurements made in a borehole using a multipole source are used for imaging a near-borehole geological formation structure and determination of its orientation. The signal to noise ratio (as defined by the ratio of the signal radiated into the formation to the axially propagating signal) depends upon the type of source (force or volume) and its position in the borehole (on the tool, in the fluid or on the borehole wall).
Abstract translation: 使用多极源在钻孔中进行的声学测量用于对近井眼地质构造结构进行成像和确定其取向。 信号噪声比（由辐射到地层中的信号与轴向传播信号的比率所定义）取决于源的类型（力或体积）及其在钻孔中的位置（在工具上，在流体或 在井壁上）。
