The invention discloses a horizontal well staged fracturing oil production method through injection and production in the same well. Multiple fracturing cracks perpendicular to a horizontal well shaft are generated at different parts of an oil layer through the horizontal well staged fracturing; one of the cracks is selected as a fluid injecting channel, and the adjacent cracks at two sides serve as crude oil production channels; displacement crude oil flows to the cracks at two sides along the crack in the middle; a double-oil-pipe segmented sealing technology is combined to seal the crack and the adjacent two cracks; a fluid is injected in from the middle crack; the displacement crude oil flows to the horizontal well shaft from the adjacent cracks at two sides; and produced liquid flows outside the shaft along another oil pipe channel to form a segmented same-well injection and production system in the same horizontal well.
