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 the product should be determined according to the field temperature and crosslinking ratio. For example, when the temperature is high, the amount of adding is 0.8% to 2%; At low temperature, the dosage is 0.2-0.4%. Sand-carrying liquid systems with different crosslinking time and crosslinking strength can be obtained by combining different organometallic Crosslinking agents.
The shelf life of emulsion products is 180 days and powder products are two years. Store in a cool, dry place.
