RESEARCH ON TREATMENT TECHNOLOGY OF HYDROGEN SULFIDE IN PRODUCTION PROCESS OF A CERTAIN OILFIELD
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 sul-fide 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 bac-teria NRB and the inhibitory effect on SRB.
