目前天然气中含有H_2S、CO_2、水等腐蚀性介质,井下油管会发生严重的腐蚀破坏。在研究区的气井进行生产开发时,由于产出来的天然气中有腐蚀介质,这些介质能够使气井油管发生很严重的腐蚀,从而破坏油管影响生产。针对目前的研究区的腐蚀情况,对气井产生的腐蚀因素进行分析,经过生产过程和实验室研究,加注适量的缓蚀剂是最有效最省开支的防腐材料。 At present, natural gas contains H 2 S, CO 2, water and other corrosive media, and the downhole tubing will undergo serious corrosion damage. When the gas wells in the study area are being developed for production, due to the corrosive medium in the natural gas produced, these mediums can cause severe corrosion of the gas well tubing, thus damaging the tubing and affecting the production. According to the corrosion status of the current study area, the corrosion factors of the gas well are analyzed. After the production process and laboratory studies, adding the appropriate amount of corrosion inhibitor is the most effective and cost-effective anti-corrosion material.
