For oil field fracturing, sand, water shut-off operation.
Fracturing in the oil field has a high viscosity, low residue, aqueous solution is good,water insoluble agents were lower underwater,
damage to the sandstone reservoir is small, easy to control rheological properties, and so easily from the bottom row of the anti-
characteristics.2 is mainly used for oil wells, hydraulic fracturing of oil and gas operations in thewater-based fracturing fluid and acidizing
fluid in the front, Takai high temperature,low-permeability reservoir fracturing thickening of the products must be used.3 is widely used in
oil field fracturing, sand, water shut-off operation.
