摘要
介绍了低于 2 0℃的超低温压裂液体系的添加剂优选及其配方 ,并对其耐温耐剪切、破胶时间、岩心伤害等性能进行了室内评价。室内试验和现场应用表明 ,该压裂液体系具有成本低、配制方便、快速破胶返排的优点 ,且增产效果明显 ,值得推广应用。
Additives' optimization and the formula of the fracturing fluid system used in low-temperature, shallow wells are introduced. Meanwhile, its comprehensive performances, such as resisting high-temperature and shear, gel breaking time and damage to core are evaluated at lab. Tests and field application show that this fracturing fluid system is cost-effective, easy to mix and fast for gel breaking. The increase of the production rate is also obvious. So it is worth being widely used.
