表面活性剂在石油工程中的应用研究进展

Research Progress in Application of Surfactants in Petroleum Engineering

表面活性剂在石油工程的油气钻井、开采及储运中均有很广泛的应用。综述了表面活性剂在石油工程中的研究及应用现状,由于国内一些大型油气藏已到开采后期,油田采收率较低,利用表面活性剂可以提高采收率。高分子类型的表面活性剂既能提高波及系数,又能提高洗油效率,是很好的驱油助剂。目前不少油田在开采低渗透油藏以及页岩油气藏,压裂液助剂的开发研究是现在及将来的一个研究热点。

Surfactants have been widely applied in petroleum engineering, such as oil/gas drilling, developing, production, storage and transportation. In this paper, current situation of research and application of surfactants in petroleum engineering was introduced. The oil recoveries in some large oil reservoirs are low because some oilfields have reached the later stage of development and production. Surfactants can be used in flooding to enhance oil recovery. Polymer-type surfactants can increase both waterflood sweep efficiency and displacement efficiency. So research on the surfactants as fracturing fluid additive will be a hot spot in development of low permeability reservoirs and shale oil/gas reservoirs.
