In fact, polyacrylamide is widely used to treat those sewage. In fact, through understanding it, it is not difficult to find that it is also widely used in the drilling industry. Let's talk about how it is applied in drilling?

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 cleaning the bottom of the well. Moreover, it has good viscosity and rheological properties, which 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 clay swelling caused by filtrate entering the formation and well wall collapse. During the drilling process, the drilling fluid will leak due to the 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 emergence not only improves the drilling efficiency, but also can treat the sewage produced after drilling.
