The invention discloses a ball-throwing type layered sand control process pipe column and a method thereof. The pipe column comprises a sand control outer pipe and a sand control inner pipe placed inside the sand control outer pipe, wherein the sand control outer pipe comprises a top suspension setting mechanism, a reverse well-flushing device, external filling devices, screen tubes and a pipe plug from top to bottom, and the top suspension setting mechanism, the reverse well-flushing device, the external filling devices, the screen tubes and the pipe plug are connected in sequence. The sand control inner tube includes a releasing mechanism, inner filling devices, a switch mechanism and a bottom positioning device from top to bottom, wherein the releasing mechanism, the inner filling devices, the switch mechanism and the bottom positioning device are connected in sequence. The number of the inner filling devices is consistent with that of the external filling devices in each oil reservoir, and the inner filling devices and the external filling devices correspond to each other in the radial direction. Internal well-flushing valves are installed between every two inner filling devices. The ball-throwing type layered sand control process pipe column and the method thereof can realize completion of layered sand control construction of a multiple zone by one-trip pipe column, ensureindependence between layers, and give full play to the productivity of each small layer to achieve the best sand control production effect.
