摘要
在油气田开采、集输和气田水回注系统中,存在着各种微生物群体,包括盐酸盐还原菌、铁细菌以及其它微生物,它们在生长、代谢、繁殖过程中,可引起集输设备、回注管线的堵塞和腐蚀,给油气田开发带来极大的经济损失。其中危害性最大的微生物就是硫酸盐还原菌。通过对重庆气矿各站场硫酸盐还原菌对气田水处理工艺及油套管腐蚀状况和分析对比,推荐一种现场运用较好的SRB防腐控制技术。
In the systems of oilfield development,gathering and transportation,and gasfield water reinjection,there are various microbial populations,including sulfate reducing bacteria( SRB),iron bacteria,and other microorganisms. They can cause the plugging of gathering and transportation equipments and the corrosion of reinjection pipelines,which brings about substantial economic loss. In particular,SRB is one of the most dangerous microbes. This study takes many stations in Chongqing Gas District as examples,and then,analyzes the gasfield water treatment processes caused by SRB in these stations,compares the corrosion condition of tubing and casing. Finally,a kind of SRB anti- corrosion technology is recommended.
