- It is shown that the delayed crosslinking time of fracturing fluid can be adjusted by changing the dosage of DCL-KB and pH value. 對DCL-KB的耐溫性、剪切恢復性、破膠性、攜砂等性能進行了評價。 結果表明,DCL_KB交聯劑耐溫耐剪切性能好,調節加量和膠液的pH值,可改變延遲交聯時間。
- 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為主劑的壓裂液耐溫耐剪切性能好、濾失量小、破膠快速徹底,而且具有良好剪切恢復能力,可滿足小眼井壓裂的需要。
