1. Product performance:
Hydrolyzed polyacrylonitrile-ammonium salt is a light yellow powder, which is a fluid loss reducer for drilling fluids. Contains -COOH, -COONH4, -CONH2, -CN and other groups, the molecular weight is between 10000-50000. It has the special function of reducing water loss due to high pressure difference and good thermal stability. The actual effect is mainly the rheology of drilling fluid, preventing clay hydration and dispersion, and has a certain resistance to salt. Due to the mosaic effect of NH4+ in the shale, it has a certain anti-slump effect.
