The invention discloses a three-layer double-pressure-regulating water injection technology pipe column, and belongs to the technical field of water injection pipe columns. The three-layer double-pressure-adjusting water injection technology pipe column comprises an oil pipe (15), and a water flow regulator, a packer and a bottom ball (8) are arranged on the oil pipe (15) in a sleeving mode. The three-layer double-pressure-adjusting water injection technology pipe column is characterized in that the oil pipe (15) is provided with pressure regulating devices, the pressure regulating devices arearranged by two groups up and down and correspondingly arranged at the upper and lower ends of the oil pipe (15) in a sleeving mode, and the pressure regulating devices are arranged between the waterflow regulator and the packer. The three-layer double-pressure-regulating water injection technology pipe column is additionally provided with two groups of pressure regulating devices up and down, and the effects that the pr
