摘要：

对油田采出污水进行处理以达到注入水水质标准,通常采用物理处理技术和化学处理技术。详细介绍了目前这两种处理技术在国内外油田的具体应用及发展现状,并提出了在常规油田、稠油油田、低渗透油田和聚合物驱油田采出水回注处理中存在的一些主要问题。最后,对未来油田采出水回注处理技术的发展趋势作了展望。

Abstract:

To treat the produced water from oilfields to meet the injection water quality standard , the physical technology and the chemical technology are often applied .The concrete application and the present progress of the two technologies in oilfields are discussed in details, and the produced water reinjection treatment problems existing in normal oilfields , viscous oil reservoirs, low permeable reservoirs and polymer-flooding oilfields are brought forward .Finally ,the developing prospect of the produced water reinjection treatment in oilfields is introduced

Key words: produced water , injection water , water treatment , water flooding
