摘要： Harmonics and subharmonics of acoustic measurements made during rotation of a sensor on a downhole are processed to estimate the location of the imager, and size and shape of the borehole. A piecewise elliptical fitting procedure may be used. These estimates may be used to correct measurements made by a standoff-sensitive formation evaluation sensor such as a neutron porosity tool.
摘要翻译： 对在井下的传感器旋转期间进行的声学测量的谐波和次谐波进行处理以估计成像器的位置，以及钻孔的尺寸和形状。 可以使用分段椭圆拟合程序。 这些估计可以用于校正由诸如中子孔隙度工具的对立敏感地层评估传感器所做的测量。

摘要： An embodiment of a communication system for communicating between a wired pipe string in a borehole and a surface location includes at least a first wired pipe downhole component and a second wired pipe downhole component in the wired pipe string, a coupler configured to transmit a transmission signal between the first wired pipe downhole component and the second wired pipe downhole component, and a wireless transmission assembly in at least one of the first wired pipe downhole component and the second wired pipe downhole component. The wireless transmission assembly is configured to wirelessly transmit a wireless transmission signal to a receiver antenna, and the receiver antenna is disposed at the surface location and configured to receive the wireless transmission signal.
