The invention belongs to the technical field of gas production of oilfields, and specifically provides a compressing type subsealing packer. The compressing type subsealing packer comprises a reversing centralizing mechanism, an anchoring mechanism and a sealing mechanism which are connected from bottom to top in sequence; the reversing centralizing mechanism comprises a lower connector, a guide center pipe, a guide pin, a guide pin carrier, a centralizing block, a centralizing block carrier and a spring; the anchoring mechanism comprises a slip box, a slip, a slip spring and a cone body; the sealing mechanism comprises a lower side ring, an outer rubber barrel, a center pipe, an inner rubber pipe, an inner center rod and a pressing cap. Compared with the general cracking packer, the compressing type subsealing packer has the advantages that the construction efficiency is high, the requirement for dragging and cracking a plurality of sections by feeding at a time can be met, and the problem that the working cost and risk are increased due to frequent putting out and feeding can be solved at the same time.
