油田开发过程中,原油含水会持续上升并不断加剧,部分油区甚至由于含水超高导致油井停产。在不断重视环保的今天,油田开发过程中的污水问题越来越突出,已等同于原油开采。如果对油田污水进行商品化经营,不仅可以获得可观的环境效益,而且有可观的经济效益和巨大的社会效益。一、油田开发中的污水问题以辽河油田为例,日产含油污水14.3万吨,占油田日产液量的77.2％,大约每生产1吨原油就要产出3.4吨污水。随着油田长期开采,含水率还将不断上升,平均每年增加2％以上,预计到2005年辽河油田的日产污水总量将突破16万吨。胜利油田开发最早的胜利采油厂,日产污水13.2万吨以上,油田综合含水已达94％以上,且有逐年增长的趋势。可见污水对环境的压力,已经成为油田环境保护工作的重点。目前,油田污水主
During the oilfield development, the water content of crude oil will continue to increase and intensify. Some oil wells even shut down oil wells due to the ultra-high water content. In the continuous emphasis on environmental protection today, the sewage problem in the process of oil field development more and more prominent, has been the same as crude oil exploration. If the commercial operation of oilfield sewage, not only can obtain considerable environmental benefits, but also have considerable economic benefits and great social benefits. First, the sewage problem in the development of oil and gas In Liaohe Oilfield, for example, Nissan oil-containing sewage 143,000 tons, accounting for 77.2% of the daily output of oil, about 1 ton of crude oil production will produce 3.4 tons of sewage. With the long-term exploitation of the oilfield, the water cut will also continue to rise, with an average annual increase of more than 2%. It is estimated that by 2005, the total daily output of sewage in the Liaohe Oilfield will exceed 160,000 tons. Shengli Oilfield development of the first victory of the oil extraction plant, Nissan more than 132,000 tons of sewage, oil field integrated water has reached 94% or more, and there is a trend of increasing year by year. Sewage can see the pressure on the environment, has become the focus of oilfield environmental protection. At present, the main oil field sewage
