本文介绍了清除注水井和采油井内聚合物堵塞物的方法，应采用的氧化剂为氧化氯或次氯酸钠。并介绍了氧化剂的使用浓度、用量、注入压力、注入浓度、接触时间、并通过实例说明了用此方法清除堵塞后、提高了注水井的注入量，增加了采油井的开采量。 This article describes a method of removing polymer blockages in water injection and production wells. The oxidant that should be used is chlorine dioxide or sodium hypochlorite. The use concentration, dosage, injection pressure, injection concentration and contact time of oxidant are introduced. By the example, it is shown that after the blockage is eliminated by this method, the injection volume of water injection well is increased and the production of production well is increased.
