摘　　要：聚合物驱油技术是目前国内各大油田三次采油技术中提高采收率的一种主要技术措施。但随着注聚的不断注入、向前推进运移,因聚合物的黏弹性以及存有不溶物残物,导致注聚井注入压力逐渐升高,出现注聚井注不够、注不进的现象日趋严重,影响正常生产。针对海上油田生产特性和注聚井情况及堵塞物的深入细致分析,通过堵塞物分析、解堵剂稳定性、聚合物解堵实验、堵塞物解堵等实验研究,室内研发出适合海上油田注聚井解堵的一种有效、安全、可靠的解堵剂。Polymer flooding is present a major technical measures to improve EOR in every big oilfield for three times. But as polymer injects continuously into and moves forward,the polymer well is a gradually increasing pressure for viscoselasticity of polymer and there is polymer wreckage.And appear the phenomenon injecting not enough and not into,and it is serious, affect the normal production.Against the features of oil production in the sea,the situation of polymer well and the detailed analysis to plugs,through a great deal of experiments and research, obtain an efficient,safe and reliable agent for the well injecting polymer.
