Product Introduction
This series of products is the main additive of fracturing fluid, which can increase the viscosity of fracturing fluid, significantly improve the sand carrying performance of fracturing fluid, and have the characteristics of reducing filtration loss, good shear resistance, and convenient construction. Reduce the types of additives, lower the cost of liquid preparation, and be suitable for large-scale construction.

Application
This series of products has the advantages of good filtration control, no residue, high temperature resistance, high viscosity, good backflow effect, easy to completely break the gel, good rheological properties, and strong sand carrying capacity for low-permeability reservoirs. During construction, it can create more ideal fracture lengths in the target oil and gas reservoirs, maintain high fracture conductivity, and improve the recovery rate of oil and gas wells while reducing damage to the formation.
