摘　　要：在石油工业众多新技术中,动电位现象已经在提高致密油储层采收率方面得以应用,在海外油田该方法取得的技术、商业方面的成功也已见诸报道。模拟效应的基本原理是预测孔隙壁上黏土由于孔喉扩大或者新吼道形成导致的胶体的运移。尽管如此,在注水井中该方面的相关工作却不多见。通过对三塘湖盆地致密油储层的岩心进行动电学实验,该文章在提高致密油储层注水效率的影响方面进行了论述。In a number of new technologies of petroleum industry, the potentiodynamic phenomenon has been applied in improving the recovery of tight oil reservoirs. And the method has also been reported in overseas oilfield by obtaining the technical, commercial success.The basic principle of the simulation effect is to predict the colloid migration of clay on pore wall which is caused by the expansion of pores or the formation of new pores. Though the relevant work is rare in the injection wells. This paper has researched the effect on increasing the efficiency of water injection of tight oil reservoir by electro-kinetics experiment of the core in Santanghu basin.
