摘　　要：针对油田常规分层注水工艺普遍存在封隔器密封有效期短、注水管柱蠕动、投捞测试成功率不高、分层计量不准等问题 ,特别针对斜井、小排量的分层注水工艺难题进行了攻关 ,开发了油套分注工艺技术。该项技术解决了一级两层分层注水问题 ,提高了分层注水有效率 ,使地质配注方案能得以准确有效地实施 ,对提高油田注水开发效果以及控水稳油、维持油田稳产高产起到了良好作用 。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.
