Fluid Loss Hydrolyzed polyacrylonitrile ammonium saltNH4-HPAN

Oil Drilling Fluid Loss NH4-HPAN quaternary ammoniumwidely used in anionic and zwitterionic-type water-based drilling fluid sys

Introduction

NH4-HPAN is light yellow powder, soluble in water and its aqueous solution is neutral. When used in drilling fluid system, it has good inhibitory fluid loss properties, as well as certain capacity of the viscosity reduction, which can effectively prevent borehole collapse and reduce downhole, can be widely used in anionic and zwitterionic-type water-based drilling fluid system.

NH4-HPAN can be used directly into the fluid or mixed with glue of 1% to 3%. General dosage is 0.5% -1.5%.
