description The invention discloses a tracer water exploration and segmented water control system and method. The tracer water exploration and segmented water control system comprises a tracer water exploration tubular column and a segmented water control tubular column arranged inside the tracer water exploration tubular column. The tracer water exploration tubular column comprises a plurality of expansion packers used for dividing a reservoir of a horizontal well into a plurality of water control sections, and tracer agent screen tubes used for obtaining oil and water information of each water control section. The adjacent expansion packers are connected by the tracer agent screen tubes. The segmented water control tubular column comprises a plurality of isolating and sealing nipples used for sealing the multiple water control sections in a segmented mode to form a plurality of sealed sections, and water control valve nipples used for water-controlled oil mining in the sealed sections. The adjacent isolating and sealin
