华北东部油田采出水对环境的影响与对策研究

The Study of Countermeasure for That the Environment was Infected by the Water Draw Out of the Oil-well on East-side in Borth of China

近年来，华北东部发现的油田数量逐年增多，伴随原油从地下采出的高矿化度地层水越来越多地流散于油区地表。室内水化学分析证实。与原油一同产出的地层水，具有含硫化物高、偏酸性、含盐度高等特点，严重影响了地表饮用水的质量、农作物的生长和植被的覆盖率。文章提出了将地下采出水回注于相对浅层砂岩水系地层中的科学水处理方法，并对两类水体性质的吻合性和回注目标层的地质特征进行了论证。这一技术方法的提出和实施将有助于解决长期以来华北东部油田采出水所造成的环境污染问题。

The near of years, the number of the oil-field on east-side in north of China is gradually increasing. The stratum water with high mineralize that draw out of the underground with oil was more and more flowed to the earth＇s surface in oil-field area.The chemical analysis of water in room showed that the water with oil have some characters, that is more sulphide, more acidity, more salinity etc. So the quality of water for drink, the growth of crop and the vegetation was severity effected. The method that water was scientific disposed was appointed in this paper, that is put the water from the underground return to the shallow stratum （the sand water system）. It was demonstrated that whether matching between the two type of the water and the geological character for aim stratum. It was helped to resolve the environment pollute issue which was lead by the water that draw from the underground in oil-field for a long time by this method.
