PAM est abbreviatio polyacrylamide. ¿Quid roles ludit in drilling?

Secco Polyacrylamide(PAM) flocculans organic high-molecular est. According to its ion type, it can be classified in anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, and zwitterionic polyacrylamide. Everyone knows that they play an important role in wastewater treatment, and it is an efficient wastewater treatment agent. In industriis such as papermaking, coal washing, mineral processing, textile, dying, feed processing, petrochemicals, biomedicine, and urban sewage treatment is widely used. It also plays an important role in geological exploration and drilling. In drilling, it is mainly used as drilling fluid. It can achieve the following effects:

Polyacrylamide

1. Polyacrylamide proprietates flocculationis fortes habet. It can flocculate the mud, rock debris in the drilling process, forming large flocks, which is convenient for cleaning the bottom of the well.

2. PAM non solum proprietates flocculationis habet, sed etiam bonas viscositates et proprietates rheological habet. During drilling, it can lubricate the drill bit and drill rod, reduce friction, lower resistance, increase drilling speed and reduce drilling costs.

3. Polyacrylamide particulas solas in fluctu fluctus fluctus fluctus protegere per adsorptionem multipunctis, effectum gelum protectionem et effectum aeris blocantem potest. It can prevent filtrate from entering the formation and causing clay water swelling and prevent well wall collapse.

4. During drilling, due to geological structure reasons, the drilling fluid will leak. In hoc case, the polyacrylamide gel can be used to plug leaks in fractures and loose rock layers.
