Oil drilling grade PAC
Key words: PAC-LV,PAC-HV, Oil drilling PAC, Polyanionic cellulose
Application: Polyanionic cellulose referred to as PAC has strong salt resistance ,temperature tolerance and anti-bacterial ability. Widely used in oil drilling as an effective water loss controller and viscosifier , especially in offshore oil drilling wells and salt water wells. HV type mainly as good mud thickener has hyperviscosity, high mud-making volume, high yield value; LV type has ultra-low viscosity, good heat and salinity tolerance and filtration.
