Zusammenfassung:The invention discloses a focusing processing method and device for array induction logging data of an inclined shaft or an inclined stratum. The method comprises the steps that according to a constructed initial stratum model, a conductivity response theoretical curve is calculated through forward modeling; performing skin effect correction and resolution matching processing on the conductivity response theoretical curve to obtain a theoretical curve with the same longitudinal resolution; judging whether the error between the theoretical curve and the actual measurement curve with the same longitudinal resolution meets the precision requirement or not, if so, performing high-frequency noise removal processing on the theoretical curve to obtain an array induction resistivity curve with a certain resolution and different detection depths, and completing focusing processing; and if not, modifying the initial stratum model, and repeating the steps until the error meets the precision requirement. The method can e
