Abstract

Aiming at the serious problem of corrosion of surface pipelines in Jiyuan Oilfield, this paper analyzes the corrosion law and corrosion mechanism of a gathering pipeline in Jiyuan Oilfield based on a variety of experiments. Research shows: through the spectrometer on the sampling pipe L245N composition analysis shows that the main elements of the pipeline tubing to meet the national standard requirements; the analysis of corrosion products and bacterial species shows that the corrosion type of this gathering pipeline is mainly CO2 corrosion and bacterial corrosion; based on the corrosion hanging experiment, it can be seen that the temperature in the temperature range of 10℃~50℃, with the increase in temperature corrosion rate becomes larger, the pressure on the pipeline corrosion rate has less impact; based on the results of water quality analysis and pipe corrosion microscopic morphology observation, the pipeline extracted water Cl- ion content is high, there is pitting corrosion, especially weld corrosion is more serious.
