Quaternary ammonium salt for anti-swelling agent

I. Product performance
This product is a new type of hyperbranched Gemini quaternary ammonium salt, which has a high Zeta potential and is easily adsorbed on the clay particles by intermolecular force, preventing the clay particles from migrating due to electrostatic repulsion, thereby effectively preventing the clay The effect of swelling reduces the hydration, swelling and dispersion of shale, which is conducive to the stability of sensitive sandstone clay minerals. This product is non-toxic and non-corrosive, and has good compatibility with various acidizing fluids, fracturing fluids, workover fluids, drilling fluids, fluid loss additives, viscosity increasing agents, lubricants, various surfactants and inorganic salts, etc. sex.

Three, product use
This product can prevent clay from swelling and migration, stabilized clay has a long effective period, and has a stable molecular structure. After being compounded with other additives, it can not only meet the requirements of oil fields with high permeability, but also meet the needs of medium and low permeability reservoir clay stabilization processes. It has good effect, strong sand control and swelling ability, and high temperature resistance. It can increase the water injection volume of water injection wells, increase oil well production, extend the operation period of oil well inspection pumps, and increase oil recovery; at the same time, it can be used in drilling fluid systems to stabilize well walls, Inhibit shale hydration expansion and dispersion, anti-sticking, anti-impedance, anti-mud bag, etc. And it has good compatibility with water and other petroleum additives.
