Summary
OBF-CS is an aqueous solution with organic ammonium salt as the main component. It is widely used in drilling and completion fluid, paper making, water treatment and other industries, and has the effect of inhibiting clay hydration expansion.
Features
It can be adsorbed on the rock surface without changing the hydrophilic and lipophilic balance on the rock surface, and can be used for drilling fluid, completion fluid, production and injection increasing.
Its inhibition of clay dispersion migration is better than DMAAC clay stabilizer.
It has good compatibility with surfactant and other treatment agents, and can be used to prepare low turbidity completion fluid to reduce the damage to oil layers.
