清洁压裂液——减少油层污染的新技术

Clean Fracturing Fluid-A New Technology to Reduce Reservoir Pollution

清洁压裂液是借助于具有一定特性的粘弹性表面活性剂,在一定环境条件下,形成稳定的棒状或蚯蚓状胶束增加液体粘弹特性以达到压裂液携悬砂的目的。该体系压裂液不仅克服了水基压裂液体系的不足,简化压裂施工工序、添加剂种类少,配液方便、压裂液性能稳定、携砂能力强,而且对储层伤害小等特点而倍受人们重视。

Clean fracturing fluid formed based on the properties of viscoelastic surfactant,and in certain environmental conditions,a stable rod-like or worm-like micelles were formed to increase the viscoelastic,which can enhance the ability of sand suspending in fracturing fluid.The system overcame the deficiencies of polymer based fracturing fluid,streamline the construction process of fracturing,less additives,with the liquid to facilitate fracturing fluid,stable performance,strong carrying capacity and less reservoir pollution.
