Water-based fracturing fluid in water as a solvent or dispersion medium

Water-based fracturing fluid in hydraulic fracturing as a solvent or dispersion medium, to join the thickener's, additives. Mainly adopts three kinds of water-soluble polymer as the viscosifier, namely plant gum (melon glue, sesbania, konjac, etc.), cellulose derivatives and synthetic polymers. Several polymer swelling into sol in water, the formation of high viscosity gel after crosslinking. With high viscosity and suspended sand ability, low fluid loss, and low friction. Use of water-based fracturing fluid at home and abroad in the following several types: natural plant gum fracturing fluid, containing such as cluster and its derivatives hydroxypropyl melon glue, hydroxypropyl carboxymethyl melon glue, delay hydration hydroxypropyl melon glue; Polysaccharide has a half milk mannose glue, such as field of wellknown and its derivatives, glucomannans glucose glue; Cellulose fracturing fluid, including such as carboxymethyl cellulose, proppant sand manufacturers  carboxymethyl hydroxyethyl cellulose, etc.; Synthetic polymer fracturing fluid containing such as polyacrylamide, partially hydrolyzed polyacrylamide, methylene polyacrylamide and its copolymers.
