纳米材料在低渗透油藏中的研究进展及展望
Research progress and prospects of nanomaterials in low-permeability reservoirs
摘要
Abstract
Nanomaterials can reduce the formation of water cluster structures and significantly reduce injection pressure.Due to their nanoscale nature,they can form a wedge-shaped separation pressure in the three-phase contact area,greatly reducing oil displacement resistance.In addition,they also have oil displacement mechanisms such as reducing interfacial tension and improving wettability,which can effectively enhance the recovery of low-permeability reservoirs.The shape of nanomaterials has a significant impact on oil displacement performance.The commonly used nanomaterials were reviewed and a detailed summary of the mechanism by which nanomaterials enhanced oil recovery was provided.The focus was on the research progress and development prospects of different shaped nanomaterials in enhanced oil recovery field.It indicated that compared to spherical nanomaterials,sheet-like nanomaterials had a clear orientation arrangement,lower interfacial free energy,stronger adsorption and great potential for application.However,the long-term stability of some sheet-like nanomaterials such as molybdenum disulfide could not be guaranteed in geological conditions,which limited their application in low-permeability reservoirs.For sheet-like nanomaterials,it was necessary to conduct in-depth research on their modification strategies and modified material properties,especially their stability in extreme high temperature and high salt condition in order to promote the development of nanomaterials in enhanced oil recovery field.关键词
