海洋石油海水淡化产生的浓盐水排放探讨

Research on discharge of concentrated brine from seawater desalination

在国内海洋石油行业中,海水淡化主要为距陆地较远、海况恶劣的海上平台提供生产淡水。近年,渤海油田对稠油开发的力度加大,当利用蒸汽吞吐等技术开采时,海水淡化也将成为取得纯水的技术之一。分析了海洋石油稠油热采海水淡化浓盐水的排放途径及面临的制约因素。

In the domestic offshore oil industry,seawater desalination mainly provides fresh water for the offshore platform which was far away from the land and the sea condition was bad.In recent years,the development of heavy oil in the Bohai Oilfield has been intensified.When steam stimulation and other technologies were used for exploitation,seawater desalination will become one of the technologies to obtain pure water.The discharge path and the constraint factors of seawater desalination and concentrated brine from offshore heavy oil thermal recovery was analyzed.
