表面活性剂驱油剂体系优选

Surfactant flooding agent system is preferred

低渗储层采用常规水驱开发采收率较低。表面活性剂驱油剂可以减少低渗储层毛管阻力作用,增加原油流动能力,对提高低渗储层的采收率具有重要的作用。本文通过测定界面张力对3种表面活性剂体系进行了评价。

Low-permeability reservoirs with conventional waterflooding have low recovery.Surfactant flooding agent can reduce the capillary resistance of low permeability reservoir and increase the flow capacity of crude oil,which plays an important role in improving the recovery of low permeability reservoir.In this paper,three surfactant systems were evaluated by measuring the interfacial tension.
