油气开采中,石油与天然气中均存在CO2(二氧化碳),其会使地面集输管道出现不同程度的腐蚀,不但会导致油气田开发过程中巨大经济损失的发生,而且,对环境还造成了不小的污染。笔者根据自身工作经验,首先指出了影响CO2腐蚀的具体因素,其次,对高含天然气集输管道的防腐对策进行了分析研究。 In oil and gas exploitation, there is CO2 (carbon dioxide) in both oil and natural gas, which will cause corrosion on the ground gathering and transporting pipe to different degrees, which will not only lead to great economic loss in the process of oil and gas field development, but also make a great impact on the environment Pollution. According to the author’s own working experience, the author first points out the specific factors that affect the CO2 corrosion. Secondly, the anticorrosion measures of the natural gas gathering pipelines are analyzed and studied.
