甘谷驿采油厂水质稳定技术研究

Study on Water Quality Stabilization Technology of Ganguyi Oil Production Plant

甘谷驿采油厂储层属特低孔隙度、超低渗透率的致密砂岩储层,注入水水质要求高,而水质成分复杂且不稳定,其中有机物含量高,矿化度高,腐蚀、结垢均很严重,水处理难度大。本文通过研究,成功解决了以上这些在甘谷驿采油厂以及我国目前油田污水回注处理工艺中普遍存在的问题。水质经处理后可达到延长油田长6油层注入水水质标准,并具有腐蚀率低、水质稳定达标等特点。

The feature of tight reservoirs in Ganguyi oil production plant was ultra-lowpermeability.The quality of injected water was extremely high.But the physicochemical property of water was very complex and unsteady,and it was not easy to treat the water.A kind of water treatment technology was developed.After being treated by this technology,the quality of the waste water of Ganguyi oil production plant reached the requirements of injected water standard in Chang-6 reservoirs,and the physicochemical property of water was steady and low corrosive.
