Development of a New Multifunctional Inhibitor for Protecting Oil Industry Equipment From Corrosion

详细

In order to protect oil industry borehole equipment and the product transport system from corrosion, and also to improve oil recovery in highly viscous oil deposits a new reagent is developed based on acidol, technical-grade isopropyl alcohol, and technical-grade phosphatide. Laboratory studies show that the reagent reduces the oil dynamic viscosity by a factor of 2.9, and is also effective as an inhibitor (the degree of overall corrosion protection is 94–96 %), while the protective effect of general corrosion is 94–96 %. Industrial testing shows that as a results of action of the reagent in the bottom-hole formation zone oil production increases on average by 22 %, and the degree of protection from overall corrosion is 90 %. Measurements also show a reduction in flow pressure in product transport pipelines 20 % from 0.12 to 0.096 MPa.
