The selection questions of the corrosion inhibitors for protection of oil-field pipelines in article are considered. Results of research of technological and anticorrosive properties the corrosion inhibitors in the environments modelling trade environments are presented. The methodological approaches to selection of the corrosion inhibitors on a stage of laboratory experiments on an example Kaverdinsky hascondancate deposits are described. It was found that all the surfactants tested in the model environment of the formation waters show a protective effect of more than 90% with a dosage of 1 g/dm3. It is recommended to use bischofite solution with a mass fraction of MgCl2 of 24% and the addition of a corrosion inhibitor КI-1M 0.1% to protect industrial gas pipelines from carbon dioxide corrosion. This composition provides a degree of corrosion protection of 99.6% relative to the model environment of the formation waters. The results of industrial tests confirmed the effectiveness of the complex system – bischofite solution with a mass fraction of MgCl2 24% and the addition of a corrosion inhibitor KI-1M 0.1%. The cationic surfactants KI-1M, St, SRK and amphoteric surfactants EM and KAPB effectively protect in a reservoir modeling environment and provide a degree of protection from carbon dioxide corrosion of 91.2-98.9%.
