|An Case Study of the Environmental Impact by the Development of Oilfield at the South China Sea
|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.
