Hydrolyzed polyacrylonitrile ammonium salt NH4-HPAN is a light yellow powder prepared by hydrolysis of acrylic fiber under high temperature and high pressure. It contains -- COOH, COONH4, CONH2, CN and other groups, and has a certain ability to resist mild and salt. It also has the function of light resistance and corrosion resistance, and has a certain anti-collapse effect due to the Mosaic effect of NH4+ in shale. This product is formed by polyacrylonitrile degradation at high temperature and high pressure, and its main components contain carboxylic acid, carboxyanyl, amide and ammonium nitrite, and its particles are not easy to caking. The product has strong functions of reducing fluid loss and high temperature and high pressure fluid loss, strong temperature resistance, good thermal stability, etc. It has certain clay hydration and anti-collapsing ability, and has good salt resistance and anti-pollution ability.
How to use:
This product can be directly applied to a variety of water-based drilling fluid system, as a filtration agent, anti-collapsing agent, and polypropylene potassium salt can be used together to enhance the effect of viscosity reduction, and can be used in combination with a variety of treatment agents. The recommended increase is 0.5% to 1.5%
The recommended addition of hydrolyzed polyacrylonitrile ammonium salt NH4-HPAN is 0.5%--1.5%
