Oil well drilling additive

The acid corrosion inhibitor is composite made with organic amine derivatives and acetylene alcohol.

The object of the present invention is to overcome the current use of temporary blocking agent is present in granular injection is difficult

Surfactant in the oil, water and gas well fracturing and acidizing used in the construction of new cleanup agent.

The agent is alcohol ether polyatomic acid, can form chelate with iron ion, and ultimately does not form a precipitate, Compared with citric acid, amino acid, they all have good stable iron ion effective, but ultimately form iron deposits.

The master agent of this product is an oil-soluble surfactant; the solvent is an alkyl group aromatic hydrocarbon.

Iron Ion Stabilizer by iron chelators and iron reductant.

During the construction process of injection, operation, drilling, fracturing and acidizing, it will inevitably produce clay swelling and migration, which reduce the formation permeability, increase the technical difficult of water injection and production.

Crude oil containing asphaltenes, resins and paraffin hydrocarbons in the molecular weight, these substances can react with acids, and even separate from crude oil.

The common working fluid used in acidification is mainly hydrochloric acid, hydrofluoric acid and other components.

A mutual solvent is soluble in either oil or water. For this reason, it is very effective in sandstone acidizing, in which it is important to keep all solids water-wet. Mutual solvents are either EGMBE or other modified glycol ethers.
