摘要： A wellbore fluid including a peroxide degradable polymer and an encapsulated peroxide source. The peroxide degradable polymer may be a polysaccharide. The peroxide source may include an inorganic peroxide, including zinc and alkaline earth metal peroxides, such as magnesium peroxide. The encapsulating material may be a polymer, including enteric polymers. The release of peroxide, from peroxide sources generally, can be controlled by means of pH such that peroxide source can be activated, and peroxide released, by a change in pH. In a wellbore, this pH change can be effected by using produced fluids to lower the pH of a more basic wellbore fluid.

摘要翻译： 包括过氧化物可降解聚合物和包封的过氧化物源的井眼流体。 过氧化物可降解聚合物可以是多糖。 过氧化物源可以包括无机过氧化物，包括锌和碱土金属过氧化物，例如过氧化镁。 封装材料可以是聚合物，包括肠溶聚合物。 通常可以通过过氧化物源释放过氧化物，通过pH可以通过pH的变化使过氧化物源活化，并释放过氧化物。 在井眼中，这种pH值变化可以通过使用产生的流体来降低更基本的井眼流体的pH来实现。
