The invention discloses a method and a device for calibrating a while-drilling remote detection electromagnetic wave resistivity logging instrument. The device comprises two elliptical discs, a fixingframe, a limiting rod, a sleeve and a fastening handle, wherein the two elliptical discs are connected and fixed by glass fiber reinforced plastics or other non-metal materials; two dials are elliptical and are made of the glass fiber reinforced plastics or other non-metal materials; the two dials are limited by a glass fiber reinforced plastic connecting rod; a middle connecting rod hole has a wire passing effect; the fixing frame is divided into an upper part and a lower part and is made of super-hard aluminum; the dials are fixed in the middle by bolts; a polytetrafluoroethylene lining isembedded in the fixing frame; a locking device is arranged at the bottom of a lower dial frame to prevent the dial frame from rotating and falling off; and full verification is performed in the designand debugging process of an instrument prototype. The device is easy to manufacture and operate; and by externally connecting a resistor and a capacitor, the complex impedance of a dial ring can be simply and accurately adjusted, so that the instrument is convenient to debug, the standard of measurement parameters is convenient to establish, and the instrument can accurately obtain required scalecoefficients of each parameter.
