摘要： A breaker fluid for breaking a filtercake in a wellbore. The fluid including a hydrolysable ester of carboxylic acid, and a chelant, an alkyl glycoside, or a combination thereof. The breaker fluid may be pre-mixed and include an amount of water less than required to completely hydrolyze the ester.
摘要翻译： 用于打破井筒中滤饼的破碎液。 所述流体包括羧酸的可水解酯，螯合剂，烷基糖苷或其组合。 破碎剂流体可以预混合并且包括少于完全水解酯所需的量的水。

摘要： A process that includes pumping a first wellbore fluid comprising an oxidative degradable polymer into a wellbore through a subterranean formation; pumping a second wellbore fluid comprising a pH-activated oxidative breaker into the wellbore; pumping a third wellbore fluid comprising a delayed acid source into the wellbore; and allowing the delayed acid source to acidify at least a portion of the wellbore to a pH of less than 7 so as to activate the pH-activated oxidative breaker at the lower pH and degrade the oxidative degradable polymers is disclosed.
摘要翻译： 一种方法，其包括将包含氧化性可降解聚合物的第一井筒流体通过地下地层泵入井眼; 将包含pH激活的氧化断裂器的第二井筒流体泵入井眼; 将包含延迟酸源的第三井筒流体泵送到井筒中; 并且允许延迟的酸源将至少一部分井眼酸化至小于7的pH，以便在较低pH下活化pH活化的氧化性破乳剂并降解氧化降解聚合物。
