摘要： An apparatus, method and computer-readable medium are provided for estimating a resistivity property of an earth formation. A logging tool includes a first antenna arrangement and a second antenna arrangement of the logging tool; and at least one device for maintaining the first antenna arrangement and the second antenna arrangement in proximity to a wall of the borehole. The first antenna arrangement and the second antenna arrangement may be at substantially the same axial location on the logging tool. Alternately, the first antenna arrangement and the second antenna arrangement may be at different axial positions on the logging tool. Extendible arms of the logging tool are configured to extend one or more of the first antenna arrangement and the second antenna arrangement against a face of the borehole.

摘要： Measurements made by a multi-component induction logging tool are corrected for tool eccentricity in a deviated borehole. The eccentricity angle is determined from single frequency skin-effect corrected data and is then used to correct multifrequency data. Multifrequency focusing is then applied to the corrected multifrequency data. An inversion is then used to recover formation resistivity and relative dip and azimuth of the borehole. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要翻译：通过多部件感应测井仪进行的测量在偏心钻孔中校正了工具偏心率。偏心角由单频皮肤效应校正数据确定，然后用于校正多频数据。然后将多频聚焦应用于校正的多频数据。然后使用反演来恢复井眼的地层电阻率和相对倾角和方位角。要强调的是，该摘要被提供以符合要求摘要的规则，这将允许搜索者或其他读者快速确定技术公开的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。
