摘要： The invention relates to an improved enhanced recovery method using polymers, wherein these polymers are preserved from mechanical degradation by adding an additive comprising sacrificial compounds. The sacrificial compounds are preferentially degraded instead of the active polymers, thus allowing optimized recovery of the oil in the petroleum reservoir. The sacrificial compounds can be polymers of same nature as the active polymers, but of higher molecular weight, or polymers of different nature having more fragile bonds. The sacrificial compound(s) is/are selected according to a lesser resistance to mechanical degradation, in comparison with the active polymers of the solution allowing enhanced recovery.
摘要翻译： 本发明涉及使用聚合物的改进的增强的回收方法，其中通过加入包含牺牲化合物的添加剂来保护这些聚合物免于机械降解。 牺牲性化合物优先降解而不是活性聚合物，从而允许石油储存器中油的最佳回收。 牺牲化合物可以是与活性聚合物相同性质但具有较高分子量的聚合物，或具有更多脆性键的不同性质的聚合物。 与溶液的活性聚合物相比，牺牲化合物根据较低的机械降解性能来选择，从而能够提高回收率。
