介绍了聚合物驱分层注入工艺技术，该技术主要是解决由笼统注入方式而导致的层间矛盾及利用常规分层配水工艺配注聚合物而出现的剪切降解问题。它主要是通过双管分注管柱来满足聚合物的分注和洗井需要，既可最大限度地避免或减小聚合物流经水咀时造成的剪切降解及铁离子的伤害，又可使射孔井段以上套管不承受高压，同时实现不同分子量不同浓度聚合物的分层定量注入，分层注入量可在地面控制，计量既简便、直观、准确，又减少了传统分层测试的劳动强度，并能较好地解决由于笼统注入方式导致的层间干扰问题。并通过现场试验论述了该项技术应用的可行性及发展前景。
In this paper, the technology of polymer flooding delamination injection is introduced. The technique is mainly to solve the problem of shear degradation caused by the general contradiction between layers and the use of conventional stratified water distribution technology with polymer injection. It is mainly through the double pipette to meet the needs of polymer dispensing and well washing wells, both to minimize or reduce polymer flow through the nozzle caused by shear degradation and iron ion damage, but also So that the casing above the perforation well section does not withstand high pressure, and at the same time, different layers of polymers with different molecular weights and different concentrations can be layered and injected in a quantitative manner. The layered injection amount can be controlled on the ground. The measurement is simple, intuitive and accurate, Labor intensity, and can better solve the problem of interlayer interference due to the general injection method. Through the field test, the feasibility and the development prospect of this technology are discussed.
