Seawater-based fracturing fluid from Huizhi holdings is suitable for offshore fracturing operations at a temperature of 80-163℃.By controlling the pH value of the working fluid, fouling can be effectively suppressed. The system has good adaptability to high-salinity water sources. When the salinity exceeds 50000mg/L, it still performs well.
