Abstract
Active and promising hydrocarbon deposits, including those on the sea shelf, are often characterized by an increased content of corrosive carbon dioxide and hydrogen sulfide. Corrosive gases present in the produced crude is a serious threat to the safety and reliability of the equipment and pipelines operating at gas production facilities. We present the results of assessing the dependence of the steel corrosion rate in the presence of CO2 on the salinity and temperature. The experimental data were processed using the methods of mathematical statistics. It is shown that the obtained dependences provide calculation of the corrosion rate with a high degree of reliability. The impact of each factor (salinity and temperature) on the steel corrosion rate was evaluated separately. The results obtained can be used to control and predict the danger of corrosion destruction of the infrastructure facilities of oil – gas fields.
