摘要
油田控制SRB的新技术是以油田中硫循环基本规律为基础,通过在注入水中添加硝酸盐/亚硝酸盐,利用地层中NRB、NR-SOB与SRB的种间竞争达到抑制SRB生物活性的效果的。这项技术已经在国外现场应用,在较短的施工周期内取得很好的效果,具有成本低,实效高,对地层没有损害的优点。本文介绍了这项新技术的应用以及国内外实验研究成果,旨在为预防和处理H2S污染提供新的技术支持。
The new technology of controlling SRB in oil field, which was based on the oilfield sulfur cycle basic rule and add nitrate or nitrite in reinjection water, taking advantage of the competition between NRB/NR - SOB and SRB to get the effect of suppressing SRB biological activity. The technology applied in foreign field achieved good effect in a relatively short period of construction cycle with the advantages of low cost, high effect and no damage to the formation. The appli- cation and research achievement of the new technology at home and abroad were introduced to provide new technical sup- port for preventing and disposing H2S pollution.
