The invention discloses an oil pipe dragging fracturing pipe column with a packer as a bottom seal and a fracturing method. The oil pipe dragging fracturing pipe column comprises a flow guide ball seat, a sand prevention hydraulic anchor, a throttling-free self-service unsetting packer, a hydraulic ejector and a hydraulic safety connector connected to the upper part of the hydraulic ejector through an oil pipe, wherein the flow guide ball seat, the sand prevention hydraulic anchor, the throttling-free self-service unsetting packer and the hydraulic ejector are sequentially connected from bottom to top. The flow guide ball seat comprises a cylindrical body, a valve ball and a baffle ring, wherein the valve ball and the baffle ring are arranged in the cylindrical body from bottom to top; andthe packer comprises a pipe body structure, a sealing mechanism and a power mechanism, wherein the sealing mechanism and the power mechanism sleeve the pipe body from bottom to top, and a compressionspring is arranged in the power mechanism and can move upwards under the hydraulic action to compress the sealing mechanism to form setting. According to the oil pipe dragging fracturing pipe columnwith the packer as the bottom seal and the fracturing method, the tripping-in safety of the fracturing tubular column can be improved, setting and unsetting are achieved through pressure changes in the fracturing tubular column, throttling is not needed, the tripping-in and tripping-out processes of the tubular column are convenient to operate, the fracturing operation efficiency is high, the costis low, the risk is small, and the oil pipe dragging fracturing pipe column can be applied and popularized on vertical wells and horizontal wells.
