DEVELOPMENT OF THE COMPLEX-ACTION REAGENT BASED ON TECHNOLOGICALLY COMPATIBLE DEMULSIFIERAND CORROSION INHIBITOR

Abstract

The authors consider the problem of developing oilfield chemicals of complex action on the example of preparation of a composite from chemicals of different process action (demulsifiers for water-oil emulsions and metal corrosion inhibitors). Unlike the common practice of empirical selection of reagents for evaluation of their action effectiveness in the technological process the offered approaches are based on the possibility of reagents selection using the inductive dielectric method. It was found that the peaks tgδ, detected by the inductive method, the most suitable for using in the complex-action composite technologically compatible oilfield chemicals, should be observed at almost equal in value frequencies. It was shown that the developed mixture of a demulsifier with a corrosion inhibitor simultaneously exhibits much higher efficiency as a corrosion inhibitor and a demulsifier, i.e. the mixture obtained is a complex-action agent.
