- It is shown that the delayed crosslinking time of fracturing fluid can be adjusted by changing the dosage of DCL-KB and pH value. 对DCL-KB的耐温性、剪切恢复性、破胶性、携砂等性能进行了评价。 结果表明,DCL_KB交联剂耐温耐剪切性能好,调节加量和胶液的pH值,可改变延迟交联时间。
- Tests indicate that the fracturing fluid containing DCL KB possesses the advan tage of adjustable delayed crosslinking time, good thermal stability, quick breaking property. 以DCL-KB为主剂的压裂液耐温耐剪切性能好、滤失量小、破胶快速彻底,而且具有良好剪切恢复能力,可满足小眼井压裂的需要。
