| 摘 要： | 含硫气井的腐蚀一直是气田开发过程中需要面对的难题,含硫气井的腐蚀主要是电化学腐蚀,影响因素主要有天然气中所含的水、H_2S的浓度、温度、pH值、CO_2等。榆林气田整体H_2S含量较低,腐蚀轻微,但由于榆20集气站含硫气井集中,从历年清管情况来看,存在一定的H_2S腐蚀。通过分析含H_2S气井的腐蚀机理和榆林气田含硫气井防腐现状,提出进一步减轻H_2S腐蚀的优化措施。

| Abstract: | The corrosion for the sour gas well is always the difficult problem faced in the pro- cess of the gas-field exploration, which is main the electrochemical corrosion. The affection factors contain the water of the gas, the concentration of H2S, temperature, pH, CO2 and so on. The general content of the Yulin gas-field is lower and the corrosion is litter. However, the sour gas well of the Yu 20 Gas gathering station is nearer. For the pigging of Yu 20 Branch line, there exists corrosion. Through analysis the corrosion mechanics and the anticorrosion status for the sour gas well of Yulin gas-field, the improvement step that abating the H2S corrosion is introduced. |
