Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.
[0037] refer to figure 1 , a dense single-layer staged treatment device for water injection wells, comprising a construction string 2, an upper packer 3, a lower packer 4, a constant pressure valve 5 and a ball valve 6.
[0038] The upper packer 3 and the lower packer 4 are arranged at intervals on the construction pipe string 2, the constant pressure valve 5 is arranged on the construction pipe string 2, and is located between the upper packer 3 and the lower packer 4, and the ball valve 6 Set at the lower end of the oil pipe.
[0039] The above-mentioned ball valve 6 includes a ball seat and a closed ball. When the plugging solution is injected into the lowermost end of the oil layer, the ball valve 6 is opened, that is, the closed ball is separated from the ball seat. When the ball v...
