摘要
可回收压裂液体系是一种新型的表面活性剂压裂液,体系具有"无残渣、低伤害、低摩阻、直接混配、可回收利用"的特点,液态稠化剂遇水混合即可快速稠化携砂,现场使用连续混配施工,同时无需添加破胶剂,地层遇原油或地层水即可实现破胶,其技术特点特别适合水平井及丛式井提速提效、节能环保和大规模工厂化作业需求。2012-2017年,该压裂液体系在长庆区域累计推广应用200口水平井(1 781段),节水降耗效果显著,并取得了较好的措施效果。今后,在低渗透油气田大规模清洁化生产改造中具有广阔的应用前景。
Recycled fracturing fluid system is a new type of surfactant fracturing fluid, it has the characteristics of ＂no residue, low damage, low friction, continuous mixed and recyclable＂. It can be quickly thickening for carry the proppant when the liquid thickener mixed with water. At the scene it uses the continuous mixed construction without adding gel breaker, the gel breaking can be realized when it encounter crude oil or water in the formation. Its technical characteristics is especially suitable for the horizontal wells and the cluster wells accelerated efficiency, energy conservation, environmental protection and large-scale factory operation. Between 2012 and 2017, the fracturing fluid system application 200 wells（1 781 sections） in horizontal wells in Changqing oilfield, water saving and reducing consumption achieve significant effect, and achieve good reservoir reconstruction effect. The system will have broad prospect of application in the large scale renovation of clean production for the low permeable oil fields in the future.
