Bridge type concentric profile control water injection allocation apparatus and process thereof

The invention provides a bridge type concentric profile control water injection allocation apparatus. The bridge type concentric profile control water injection allocation apparatus is composed of a bridge type concentric profile control water injection allocation unit and a profile control stopper. The bridge type concentric profile control water injection allocation unit is composed of an upper joint, a positioning and anti-reverse cylinder, a connecting cylinder, a concentric adjusting cylinder, a main body, a fixed pedestal and a lower joint. The invention also provides a bridge type concentric profile control water injection allocation process, and belongs to the technical field of oil field separated layer water injection. According to the invention, bridge type concentric water injection well profile control operation can be carried out without pulling strings, a profile control agent injection process meets low-shear requirements, problems in the prior that a profile control operation process is complex, a profile control agent is subjected to high shear effects, and the operation has large risks are solved, the water injection well separated layer profile control efficiency and success rate are greatly improved, and the operation cost is reduced.
