【摘要】：针对纤维压裂液的降解能力问题,设计了室内实验,研究了温度、碱浓度对纤维压裂液降解能力的影响。实验表明,KTL1型纤维在10 d内无论是水解还是碱解降解率都低于60%,不适合工程使用;KTL2型纤维在75℃时,无论是水解还是碱解降解率都不超过40%,在储层温度为75℃时不适合工程使用;储层温度为100℃时,经过16 h后,降解率已达到90%以上;储层温度为120℃时,经过4 h后,降解率已达到90%以上;因此,建议在储层温度低于90℃时慎用KTL2型纤维,在储层温度高于90℃时选做工程使用,效果较好。最后评价了纤维压裂液的携砂能力和储层伤害,对长庆油田纤维压裂液的使用具有指导意义。
[Abstract]:Aiming at the degradation ability of fiber fracturing fluid, laboratory experiments were designed to study the effects of temperature and alkali concentration on the degradation ability of fiber fracturing fluid. The experimental results show that the degradation rate of KTL1 type fiber is lower than 60% in 10 days, and it is not suitable for engineering use when KTL2 type fiber is used at 75 鈩，
