20^#低碳钢腐蚀因素分析

Corrosion Factors Analysis on 20^# Low Carbon Steel

油气田生产系统中钢材的腐蚀严重影响了油田的正常生产。研究认为油气田生产系统中钢材的腐蚀程度取决于钢材所处的环境和钢材的材质。选取一种常用的钢材20#进行腐蚀因素影响分析,考察了温度、CL-1含量、Ca2+和Mg2+含量等因素对腐蚀速率的影响。实验发现上述因素对钢材腐蚀速率和规律影响程度差别很大,在不同的环境下需要考虑的因素也有差异,这为以后钢材防腐蚀提供了一定的理论依据。

Steel corrosion in oil and gas production systems seriously affected the normal production of the oil-field, studies suggested that the corrosion of steel in oil and gas production system depended on the steel environ-ment and tile steel material, and selected a commonly used steel 20^# to analysis corrosion factors, and studied the factors such as temperature, Cl^-1 content, Ca^2＋ and Mg^2＋ content effecting corrosion rate. It is found that the above factors varied widely on steel corrosion rates and patterns of impact, and the factors to be considered in differ-ent circumstances were also different, which provides certain theoretical basis for steel corrosion resistance.
