渤海湾地区油田采出水的处理方法探讨

随着渤海湾地区几个油田在高含水期的大范围开发 ,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 ,对当地生态环境带来了严重影响。通过对地下采出水的化学分析鉴定 ,提出了将相对深部地下水回注于相对浅层砂岩水系地层中的科学水处理方法 ,并对两相水体的匹配性和回注地层的地质特征进行了论证。这一技术思路的提出和实施将有助于长期以来渤海湾地区油田采出水污染问题的解决

Discussing for the Method of Treat with the Water which Draw out from the Underground of Oilfields in the Area of BOHAI Gulf

Along with the much of Oil-fields development during the rich containing-water in the area of BOHAI gulf, the more and more high-mineralization stratum-water which draw out from the underground have flowed spread to the earth's surface and the local environment was damaged seriously. According to the analysis from the testing results of the groundwater, the scientific method was developed to treat with the contaminative water that put the groundwater into the shallow stratum reservoir. The matching possibility for the two types of liquid have been proved and the geological characteristics have been demonstrated by some of the testing dates. This method will help to solve the problem about the underground water which in the BOHAI gulf oilfield existed for a long time in the future
