孤东油田含油污泥现状及处理技术

含油污泥是油田开发过程中的重要污染源,孤东油田目前对含油污泥主要采用自然干化填埋处理法。为了更好地回收原油,提高环境效益和经济效益,实验用离心分离法处理含油污泥,结果表明:使用该技术使油回收率可以达到80%以上。当含油量达到一定值时,会产生明显的经济、环境及社会效益。

The Current Status of Oily Sludge and its Treatment Technique in Gudong Oilfield

Oily sludge is an major pollution source during the development of oilfield. Natural drying and burial method have been mainly adopted for the oily sludge in Gudong oilfield at present. To recycle the petroleum more efficiently, improve the environmental efficiency and economic benefit as well, the method of centrifugal separation has been adopted experimentally to treat the oily sludge. The experimental result shows that recycle rate of this technique could hit 80%. While the oil content of the sludge reach certain level, obvious economic, environment and social benefit could be achieved.
