How about oilfield crude oil cleaning agents?

The crude oil cleaner is a kind of high efficiency cleaning agent for removing oil scale. It is a water-based cleaning agent specially used for cleaning oil scale wax deposition in Oil pipeline, which is composed of surface active agent other additives. It has strong oil solubility, high cleaning efficiency, good corrosion inhibition performance. This agent is non-toxic, odorless, non flammable, non explosive. It is easy to use, safe, harmless to the human body, has no pollution to the environment. Petroleum additives

This product is also widely used for the cleaning of crude oil pipelines, tanks, equipment, containers, tools, filter materials, well cleaning operations, various downhole tools, other fuel equipment in industries such as offshore drilling platforms, oil fields, refining. The usage method of crude oil cleaning agent: generally use a concentration of 2-5% stir evenly. Crude oil cleaner is a combination of various surface active agents organic additives. It has excellent permeability, emulsification, ability to remove crude oil. It has good solubility in water, is simple convenient to use, can be directly discharged after use. It is suitable for dissolving insoluble substances such as crude oil gum asphalt, cleaning surface precipitated oil stains.

The increasing depth of heavy oil extraction the complexity of geological conditions require emulsified viscosity reducers to be resistant to high temperatures mineral salts. Although petroleum sulfonates are inexpensive have been successfully applied in some oil fields, they have poor resistance to mineral salts due to their anionic emulsification viscosity reducing properties. Although the method of combining anionic non ionic surface active agents can partially solve this problem, the use of non ionic anionic composite emulsion viscosity reducing agents can cause "chromatographic" separation in the formation, which cannot avoid changes in the properties states of the composite system in the formation.

The Research Institute of Petroleum Chemical Technology has proposed a new approach to improve the salt resistance of emulsion viscosity reducers. By condensing anionic non ionic functional groups in the same molecule, a ternary emulsion viscosity reducer with sulfonic acid, carboxylic acid, polyether was synthesized. The emulsion viscosity reduction effect of this co Condensation polymer has no obvious change before after high temperature treatment at 350 ℃; In mineralized water with a calcium magnesium ion concentration of 2000 mg/L, its viscosity reduction rate still exceeds 90%, which is superior to sulfonate phosphate type emulsion viscosity reducers. Similar products include LB viscosity reducers.
