Abstract

For routine cleaning fracturing fluid system:1.5%~2%VES+0.4%~0.5%NaSal,KCl can reduce the rheology of the cleaning fracturing fluid;while crude oil has little effect to break cleaning fracturing fluid,fresh water and salt water is also very limited to break cleaning fracturing fluid;terpineol and oil acids can be used as breaker,but dosage is large and can not completely break cleaning fracturing fluid;0.2% octanol,0.1% SDS,0.1% SDBS can let clean fracturing fluid quickly break,and the viscosity will be less than 5 mPa·s.
