Analysis of the efficient complex application of zinc coatings such as sherardizing on tubing surface and carbon dioxide inhibitors during the natural gas extraction on Lutsenkivske gas condensate deposit wells has been carried out. Microstructural and electrochemical investigations of zinc diffusion layer have been conducted. Existing industrial experience shows that the complex corrosion protection significantly increases the life of wells, which significantly increases the economic performance and prevents environmental pollution.
