The invention provides a partition recovery packer and a partition recovery construction method and relates to the technical field of oil recovery of an oil-gas field. The partition recovery packer comprises a packer body and a conveying pipe column; the packer body is a hollow pipe and comprises a diameter expansion segment, a transition segment and a setting segment from the lower end to the upper end in sequence, the outer diameter of the diameter expansion segment is larger than that of the setting segment, and multiple sealing rings are annularly arranged on the outer wall of the settingsegment; the conveying pipe column comprises an oil pipe and a pull rod, the oil pipe sleeves the pull rod, the lower end of the oil pipe and a setting cone are fixedly connected to form a setting mechanism, and the lower end of the pull rod and a setting plug are fixedly connected to form a plugging mechanism; an annular cavity is formed between the setting mechanism and the plugging mechanism, the setting cone can slide from the diameter expansion segment to the setting segment through the transition segment under the effect of pressure liquid, and the setting segment and the sealing rings are expanded. According to the partition recovery packer and the partition recovery construction method, the factors of the packer failure cussed by pipe column motion, rubber sleeve shoulder protrusion and the like can be eliminated, and the packer and the method can also be beneficial to downward construction of following oil pumping and pipe column production.
