| description | The utility model provides a constant proportion dropping-fishing-free seperated layer water injection technique tubular pipe so as to overcome the shortcomings that dropping-fishing is difficult and requirements for water injection can not be met when an existing seperated layer water injection tubular pipe is applied to a deep well, a highly-deviated well and a horizontal well. A packer I, a dropping-fishing-free quantitative water distributor I, a packer II, a dropping-fishing-free quantitative water distributor II and a ball seat are fixedly connected through oil pipes and mounted in sequence from top to bottom; the dropping-fishing-free quantitative water distributor I is located on a water injection layer I, the dropping-fishing-free quantitative water distributor II is located on the water injection layer II, the upper end of the packer I is connected with a wellhead Christmas tree through a pipeline; one end of a constant flow water distribution device is connected with a water injection pipeline; the |
