ys-1低温破胶助剂HPG压裂液体系的研究

Study of the Low Temperature Breaker-Activating Agent ys-1 for HPG Fracturing Fluid System

室内研制出一种新型ys-1低温破胶助剂,研究了该低温破胶助剂对压裂液性能的影响。结果表明:在破胶助剂ys-1/APS破胶体系的作用下,能使有机硼作交联剂的HPG压裂液在低温(15℃～30℃)条件下彻底破胶水化,该破胶助剂稳定性好、应用简便、用量少且成本低廉,具有现场推广使用价值。

A new type of low temperature breaker-activating agent,ys-1,was developed in lab for HPG fracturing fluid,and the influence of breaker-activating agent on the fracturing fluid was researched. The results show thatthe cross-linked HPG fracturing fluid by organic boron canbe completely destroyed by ys-1/APS at low temperature(15℃～30℃).The breaker-activating agent has the advantages of good stability,convenient application,less dos-age and low cost.
