How to use four ram coiled tubing sealer

The invention relates to a method for using a four-gate continuous coiled tubing packer. The packer comprises a main casing and a hydraulic cylinder, wherein the inner cavity of the main casing is sequentially provided with a full sealing device, a shearing device, a suspension device and a semi-sealing device from top to bottom. During sealing, a support and a return spring are closed through gates to support a sealing carrier on the lower end surface of an upper joint to achieve the sealing. During repair, the gates are hydraulically driven to open to move a piston group down and push away the sealing carrier to further press the sealing carrier down and enable the sealing carrier to rotate around a gate rotating shaft, and coiled tubing can be lowered into a well along the upper joint inner cavity. The packer has the advantage that the operation space is expanded since the full seal is of a vertical structure, that is, at least one double wing is removed, the personal injury accident in the operation is greatly reduced, the overall weight is greatly reduced, and the operation difficulty and the processing cost are reduced.
