The polyacrylamide for drilling produced by zikun company has the following characteristics:

A: High viscosity, fast starting viscosity, instant product B: salt resistance, no loss of viscosity in the environment of salinity. C: The viscosity lasts for a long time and is not easy to degrade.

The application in the drilling industry has the following advantage aspects:

1. Polyacrylamide can be used for drilling flocculation and wastewater treatment. It has strong flocculation and can flocculate mud and rock cuttings during drilling to form a large flocculation group, which is convenient for bottom hole cleaning. In addition, it also has good viscosity and rheological properties. It can lubricate the bit and drill pipe during drilling, reduce friction, reduce resistance, improve drilling speed and reduce drilling cost.

2. polyacrylamide protects the sol particles in the drilling fluid through multi-point adsorption, gel protection and gel plugging to prevent the filtrate from entering the formation and causing clay expansion and well wall collapse. During drilling, drilling fluid will leak due to geological structure. It can be used to plug cracks and loose rock formations.

In the above content introduction, the application of Polyacrylamide in drilling is mainly introduced. Its appearance not only improves the drilling efficiency, but also can treat the sewage produced after drilling.
