PAM is short for polyacrylamide, what are the roles it plays in piling?
Polyacrylamide (PAM) is an organic polymer flocculant, which can be divided into anionic polyacrylamide, cationic polyacrylamide, non-ionic polyacrylamide and zwitterionic polyacrylamide according to ionic type. We all know that they play an important role in wastewater treatment, is an efficient wastewater treatment agent, in paper making, coal washing, mineral processing, textile, printing and dyeing, feed processing, petrochemical, biomedicine, urban sewage treatment and other industries have a wide range of applications. It also plays an important role in site exploration and drilling. It is mainly used as drilling fluid in drilling. It can play the following roles:
polyacrylamide
1. Polyacrylamide has strong flocculation, which can flocculate mud and cuttings in the drilling process to form large floc, which is easy to clean the bottom of the well.
2, in addition to flocculation, PAM also has a good viscosity and rheology, in the drilling process can lubricate the drill bit and drill pipe, reduce friction, reduce resistance, improve drilling speed, reduce drilling costs.
3. Polyacrylamide can protect the sol particles in drilling fluid through multi-point adsorption, adhesive protection and void blocking, prevent the filtrate from entering the formation to cause clay water swelling and prevent wall collapse.
4, in the drilling process, due to geological structure, drilling fluid will be lost, only with polyacrylamide gel can crack, loose rock for plugging.
