某油田生产流程硫化氢治理技术研究

RESEARCH ON TREATMENT TECHNOLOGY OF HYDROGEN SULFIDE IN PRODUCTION PROCESS OF A CERTAIN OILFIELD

通过分析某油田的生产历史和硫化氢成因机理,制定针对性的生产流程硫化氢治理方案,并在现场采用两种治理药剂,对油田生产流程中的硫化氢污染进行加药治理。通过对现场生产水中SO42-、S2-、VFA及伴生气中的硫化氢浓度检测结果说明,两种药剂均有明显治理效果;在硫化氢浓度和产量两个指标上分析,药剂I的治理效果优于药剂II的治理效果;同时两种药剂均对有益菌NRB的增殖和SRB的抑制效果起到促进作用。

By analyzing the production history and mechanism of hydrogen sulfide formation in a certain oilfield,a targeted hydrogen sulfide treatment plan for the production process is formulated,and two treatment agents are used on site to treat hydrogen sulfide pollution in the oilfield production process.The results of detecting the concentrations of SO42-,S2-,VFA and hydrogen sulfide in on-site production water indicate that both agents have significant treatment effects.In terms of hydrogen sulfide concentration and production,the treatment effect of Agent I is better than that of Agent II;both drugs have a promoting effect on the proliferation of beneficial bacteria NRB and the inhibitory effect on SRB.
