纳米纤维素材料在油气田开发中的应用与展望

材料是油气田开发的基础和保障,积极借鉴材料科学的最新进展,提高油气资源开发的经济效益,减小环境保护的压力,是石油工程发展的必然要求和必由之路。作为一种高性能的生物高分子材料,纳米纤维素(NC)具有成本低、来源广、无污染和可再生等优点以及高强度、低密度、强韧性、易修饰等物理性质,被广泛应用于生物医药、食品包装和光电材料等领域。最新研究表明,NC材料在油气田开发领域也具有广阔的应用前景,并逐渐引起中外学者的关注。详细梳理了近年来NC在钻井、压裂和提高采收率等方面的研究进展,深度剖析了实际应用中遇到的问题和解决方法,结合近年来对NC分散液、NC高稳泡沫、NC乳液和NC水凝胶的研究,展望了未来NC材料在油气田开发中的应用潜力和发展方向。

Application and prospect of nano-cellulosic materials in the development of oil and gas field

Materials are the foundation and guarantee for the development of oil and gas reservoirs.Actively drawing on the latest progress in material science,improving the economic benefits of oil and gas resources development,and reducing the pressure on environmental protection are the inevitable requirements and the only way for the development of petroleum en gineering.As a high-performance biopolymer material,the nano-cellulosic(NC)material has the advantages of low cost,wide sources,no pollution,and renewable,as well as physical properties such as high strength,low density,strong tough ness,and easy modification.It is widely used in the fields of biomedicine,food packaging and photoelectric materials.The latest researches show that the NC material also has broad application prospects in the development of oil and gas reser voirs,and has gradually attracted the attention of Chinese and foreign scholars.The research progress of NC in drilling,frac turing and EOR in recent years has been summarized in detail,and the technical issues and solutions encountered in practi cal applications have been analyzed in depth.Based on the recent research on NC dispersions,NC high-stability foams,NC emulsions and NC hydrogels,the application potential and development direction of NC materials in oil and gas field devel opment are prospected in the future.
