The utility model relates to a multistage subdivision water injection well augmented injection construction pipe column for oil field water injection well's augmented injection job execution. This construction pipe column links together as combination acidizing instrument including throttle sprayer, packer, acceptor and backwashing valve, will throttle sprayer, packer and acceptor, will make up the acidizing instrument most likely and connect the oil reservoir position gone into down to the well in oil pipe, and backwashing valve and throttle sprayer are connected to oil pipe's bottom. According to the design of oil reservoir position, connected augmented injection construction pipe column, once go into the well and target in place, the successive layer is thrown throttle sprayer, the ballsealer of throwing that the ball sealer opened in the combination acidizing instrument and is held by the acceptor from bottom to top, the successive layer augmented injection is under construction.And need not make a round
