Drag reduction agent

Product features
This product is a solid powder or emulsion of a polyacrylamide copolymer used in water-based fracturing fluids to reduce the friction coefficient when fracturing fluids flow, thus reducing pressure loss. The powder or emulsion resistance-reducing agent can disperse and dissolve in water quickly, with quick effect, and can be applied to on-site mixing equipment. In addition, this series of products also has good salt resistance performance, can be suitable for the backflow of fracturing fluid reformulation and reinjection.

 Method of application
 The addition amount can be adjusted according to the field conditions to obtain good resistance reduction performance. The addition amount of powder and emulsion is usually 0.01%-0.02% and 0.05%-0.3% respectively in water and liquid mixing. The dosage will be increased to 0.02-0.05% (powder) and 0.3-0.8% (emulsion) if prepared with field return drainage. Both types of products can be mixed online.

The shelf life of emulsion products is 180 days, and that of powder products is two years. Store in a dry and cool place.
