According to incomplete estimation, in the Ordos Basin, about 3 million m3 of fracturing fluid is pumped downhole each year, about 50% is flowed back. This fluid contains a lot of colloidal dispersion, chemicals, heavy metals and many harmful elements, it not only cannot be discharged directly and reused straightaway, but also creates water wastage and environmental hazards.
