DETECÇÃO DE EFEITOS DE FURO DE POÇO DEVIDO À EXCENTRICIDADE EM ISNTRUMENTOS DE INDUÇÃO COM TRANSDUTORES INCLINADOS |
摘要 |
An apparatus, method and computer-readable medium for evaluating an earth formation are disclosed. A logging tool which has two coplanar antennas disposed at a known distance from an axis of the logging tool is conveyed into a borehole. The presence of a borehole effect is determined from a difference between outputs of the two antennas. The borehole effect may include eccentering of the logging tool in the borehole. Measurements made by an additional antenna and/or the two coplanar antennas may be corrected for the effects of eccentering. Horizontal and vertical formation resistivity as well as additional petrophysical properties may be determined. |
