Product features
The product is a kind of polyacrylamide copolymer solid powder or emulsion, applied to water-based fracturing fluid to reduce the friction coefficient of fracturing fluid flow, thereby reducing pressure loss. The powder or emulsion can be quickly dispersed and dissolved in water, with quick effect, and can be applied to the on-site online mixing equipment. In addition, this series of products also has good salt resistance, can be used for the reinjection of backflowback fracturing fluid.

Method of application
The amount of adding can be adjusted according to site conditions to obtain good drag reduction performance. When mixing liquid in clear water, the amount of powder is usually 0.01%-0.02%, and the amount of emulsion is 0.05%-0.3%. If prepared with field flowback drainage, Dosage could be increased to 0.02-0.05 per cent (powder) and 0.3 -0.8 per cent (emulsion).
The shelf life of emulsion is 180 days, and the shelf life of powder product is two years. Store in a cool, dry place.
