Summary:The utility model relates to a separately flooding tension bearing device of a flooding well oil pipe, which is characterized in that a snap clamp 4 arranged outside a central pipe 2 clings to a groove of the inner wall of a long coupling 3. The separately flooding tension bearing device of the flooding well oil pipe has simple structure, convenient use, reliable working and low processing cost, and can be widely used for three-pipe separately flooding processes of various flooding wells. Particularly, when used for deep well flooding, the separately flooding tension bearing device for the flooding well oil pipe can obviously increase the use depth of the three-pipe separately flooding processes and improve the development effect of oil fields.
