摘　　要：在我国低渗油藏开发中,面临复杂多变的地质条件,如何提高采收效率是一个关键难题,纳米材料的出现为解决这一难题提供了全新的思路。纳米材料具有小尺寸和高活性的特点,可与多种化学物质合成纳米驱油剂,能够在地层微观尺度上发挥作用,有效改善油水相对渗透率,增加原油的驱出率,从而提高采油效率。基于此,本文在总结纳米材料四大基本性能的基础上,综述不同纳米材料在提高原油采收率方面的应用,深入探讨纳米材料驱油的作用机制,以揭示其在油田开采中的重要作用,最后展望了纳米材料驱油的前景。通过纳米材料技术的应用,有望更有效地开发和利用油田资源,推动能源行业的可持续发展。In the development of low permeability reservoir in China,how to improve the recovery efficiency is a key problem in the face of complex and changeable geological conditions.The appearance of nanomaterials provides a new way to solve this problem.Nano materials have the characteristics of small size and high activity,and can be combined with a variety of chemicals to synthesize nano-oil flooding agents,which can play a role in the formation of micro-scale,and can effectively improve the relative permeability of oil and water,and increase the displacement rate of crude oil,leading to the improving of the oil recovery efficiency.Based on the basis of summarizing the four basic properties of nanomaterials,the application of different nanomaterials in enhanced oil recovery was reviewed,and the mechanism of nano-oil flooding agents was deeply discussed to reveal its important role in oilfield exploitation.Finally,the prospect of nano flooding was prospected.Through the application of nanomaterials technology,we are expected to develop and utilize oilfield resources more effectively and promote the sustainable development of the energy industry.
