Zusammenfassung:	The invention provides a steam flow control well completion pipe string, and belongs to the technical field of underground production casing pipe strings. The well completion flow control device is composed of a hanger arranged on a casing, a well completion flow control unit and a screwed plug. And the well completion flow control unit is respectively connected with the screwed plug and the hanger. The well completion flow control unit is composed of a plurality of underground injection and production two-way control devices and packers, and one packer is arranged between every two underground injection and production two-way control devices. The screwed plug is connected with the underground injection and production bidirectional control device in the well completion flow control unit corresponding to the lowest oil layer, and then the underground injection and production bidirectional control device is sequentially connected with the packer and the underground injection and production bidirectional control
