Keywords: protection against corrosion, volatile corrosion inhibitors, conservation of oil field equipment

The goal of this work is the analysis of modern state of problem of application of volatile corrosion inhibitors (VCI) on objects of oil-and-gas complex and perspective directions of development of volatile corrosion inhibitors.
In the process of work, on the basis of literary data, the information about economic damage from corrosion is presented, the mechanism of protective action of inhibitors is described, historical inquiry about development of this direction in inhibitor protection is given. Synthesis methods, laboratory testing and determination of VCI in vapor phase are shown. Cases of appearance of corrosion in vapor phase on objects of oil-and-gas complex, protective methods with a help of VCI, cases of successful application and corrosion monitoring methods
in vapor phase are considered. Perspective directions of VCI developments are indicated.
