| Abstract: | The conventional separate-layer water injectiontechnology has such problemg as nondurable packer sealing,creep deformation of string,low Success rate of testing by pulling and running and inaccuracy of separate-layer metering.Therefore a separate-layer water injection technology through tubing and casing is developed especially for operation in deflecting wells and small-displacement wells,solving the problem of water injcction of two layers by one packer.This technology is proved effective and beneficial. |

| Keywords: | separate-layer water injection water injection through tubing and casing deflecting well water injection string |
