| 摘 要： | 对解堵体系JD性能进行了评价，结果表明，JD解堵体系对聚合物溶液的降解率大于98．5％，且温度升高，降解时间缩短；现场垢样总溶蚀率大于79％；注聚岩心流动试验解堵率为157％；JD体系对金属腐蚀速率很低，适合现场应用。JD解堵体系在SZ36—1-J03注聚井现场酸化解堵应用结果表明，目标层注入量大幅提高，达到了注聚井解堵的目的。

| Abstract: | The plug remover JD was evaluated.The result showed that the plug remover JD had the degradation rate of over 98.5% for polymer solution.The degradation time shortened with the rise of temperature.On-site corrosion rate for scale was greater than 79%,blocking rate for polymer-injection core in flow test was 157%.The plug remover had very low corrosion rate for metal,and therefore was suitable for field application.The application of plug remover JD in SZ36-1-J03 polymer-injection well showed that the amount injected into the target formation was substantially increased and the plug remover could get good result. |
