Corrosion and scale inhibitor polycarboxylic acid for oil production

Corrosion and scale inhibitor polycarboxylic acid for oil production

Chemical Name
Molecular Formula

【product manual】

  This product is a composite corrosion and scale inhibitor composed of a variety of organic phosphonic acids, polycarboxylic acids, sulfonate-containing copolymers, copper corrosion inhibitors, special surfactants, etc., using organic phosphonates to form on the metal surface The protective film plays a corrosion-inhibiting effect, and at the same time has a good chelating dispersion and lattice distortion effect on calcium carbonate, calcium sulfate, calcium phosphate, etc. in the water. According to the principle of reasonable proportioning, the synergistic effect is fully exerted, and it has the characteristics of high corrosion inhibition rate, high temperature resistance, strong scale inhibition, and difficult decomposition.


  It is mainly used in the oil production process to prevent the scale and corrosion of equipment, containers and pipelines caused by injected water, and to protect equipment, containers and pipelines.
