摘要
An oil-gas well structure and a segmental flow-control method for a flow-control filter string (5) used in the oil-gas well. The segmental flow-control method for the flow-control filter string (5) comprises the following steps: 1) establishing a channel (2-1); 2) running the flow-control filter string (5); 3) filling with the anti-channeling flow pack-off particles (7); 4) sealing; 5) disconnecting a run-in string connected to the flow-control filter string (5). The segment flow control of the flow-control filter string (5) is achieved by using a pack-off effect of the anti-channeling flow pack-off particles (7).
