В работе представлены результаты исследования состава продуктов углекислотной коррозии методом рентгеновской дифракции. При углекислотной коррозии в ходе растворения стали основной продукт — FeCO3. Для сидерита характерно явление изоморфизма в кристаллической структуре (изменение химического состава фазы при сохранении ее кристаллической структуры). При этом часть ионов железа в FeCO3 может замещаться ионами марганца, кальция, магния. Установлено, что фазы образующихся осадков нестехиометрического состава (CaxMgyMnzFe)CO3 плохо окристаллизованы. Это связано с наличием дефектов в кристаллической структуре. Они будут иметь худшие защитные свойства по сравнению со стехиометрическим FeCO3, пленка которого упакована, равномерно распределена и плотно прилегает к поверхности стали. Анализ дифрактограмм свидетельствует о хорошей окристаллизованности FeCO3, форма частиц которого стремится к правильному гексагональному габитусу. Полученные результаты могут быть использованы при исследовании стойкости продуктов коррозии, образующихся на внутренних поверхностях оборудования газодобычи в агрессивных условиях присутствия CO2 в добываемых и транспортируемых углеводородах.</p></abstract><trans-abstract xml:lang="en"><p>The internal carbon dioxide corrosion is one of the most common types of corrosion in the gas fields development. The results of studying the composition of carbon dioxide corrosion products by X-ray diffraction method are presented. FeCO3 is the main product resulting from dissolution of steel upon carbon dioxide corrosion. Siderite is characterized by the phenomenon of isomorphism in the crystal structure (a change in the chemical composition of the phase at the same crystal structure). In this case, some of the iron ions in FeCO3 can be replaced by manganese, calcium, and magnesium ions. It is shown that phases of the precipitates of non-stoichiometric composition (CaxMgyMnzFe)CO3 thus formed are poorly crystallized which is attributed to the presence of defects in the crystal structure. They will exhibit inferior protective properties compared to stoichiometric FeCO3. The film of FeCO3 is packed, uniformly distributed and tightly adhering to the steel surface. An analysis of the diffraction patterns revealed a good crystallization of FeCO3. The shape of FeCO3 particles tends to a regular hexagonal habitus. The results obtained can be used in studying the resistance of corrosion products formed on the internal surfaces of gas production equipment under aggressive conditions in the presence of CO2 in produced and transported hydrocarbons.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рентгеновская дифракция</kwd><kwd>продукты коррозии</kwd><kwd>углекислотная коррозия</kwd><kwd>карбонат железа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>X-ray diffraction</kwd><kwd>corrosion products</kwd><kwd>carbon dioxide corrosion</kwd><kwd>iron carbonate</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kantyukov R.
