南海油田开发环境影响实例分析

国家海洋局南海环境监测中心,广东 广州 510300
摘要:
陆丰22-1是中国第一个正式弃置的海上油田,处于南海330m深水区。通过分析开发前、开发中期和开发末期油田附近海域表层海水、表层沉积物和底栖甲壳类体内石油烃含量数据,结果表明油田附近海域环境质量较好,油田开发对环境的污染影响较小,主要影响是表层海水和底栖生物体内石油类污染物质含量有所升高,尚未见生活污水和食品废弃物的排放对环境造成的影响迹象。含石油类污染物质的排放是海上油田开发环境保护中首要关注的污染因子。建议将污染监测的必测指标优化为:表层海水中油类和底栖生物体内石油烃含量。

An Case Study of the Environmental Impact by the Development of Oilfield at the South China Sea
Abstract:
The Lufeng 22-1 oilfield is the first decommissioned oilfield of China, which located at the profundal zone with the depth of 330 m in the South China Sea. According to the amount of discharged pollutant in the production period, with survey data of surface water, surface sediments and marine organisms around the oilfield area at August 1990, July 2003 and Apr~May 2008, the marine environmental impacts in the development period of Lufeng 22-1 oilfield had been studied. The results showed that the content of petroleum in surface water and benthos body increased, but no significant adverse impact on the water quality because of the sewage and food waste emissions. The sewage contained oil pollutants is the first pollution factor in the offshore oilfield development. It is suggested that monitoring index should be the oil concentration in surface seawater and oil contents in benthos body.
