天83站污水硫化物来源分析

Analysis of the source of sulfides in the wastewater of Tian 83 Station

江苏油田天83污水站硫化物高达68mg/L,跟注水系统硫化物2mg/L的推荐指标相比,超标严重,造成天83污水系统水体发黑发臭,水质不达标,腐蚀超标。本文通过岩心成分测试、细菌培养和硫元素同位素测定3个方面对硫化物的来源开展分析,确定了天83站的硫化物来源主要是生物成因,为天83站硫化物治理提供了依据。

The sulfide content of Tian 83 in Jiangsu Oilfield is up to 68mg/L and seriously beyond the recommended standard(2mg/L)of water injection system.Because of that,the wastewater of Tian 83 Station become black and smelly with off-specification of corrosion.In this paper,the core component determination,bacterial culture and sulfur isotopic determination was carried out to analyze the source of sulfide.And the sulfidesin the wastewater of Tian 83 Station is biogenic,which provides theoretical basis of the treatment of sulfides.
