纳米颗粒驱油机理研究进展
Research Progress on the Mechanism of Oil Displacement by Nanoparticles
摘要
Abstract
In recent years,nanoparticles have gradually received widespread attention in tertiary oil recovery.At present,the mechanism and development status of nanoparticle are not well understood.For this reason,the paper systematically analyzes research progress of nanoparticle flooding in recent years and summarizes the mechanisms of oil displacement by nanoparticles,including nano-size effects,reduction of interfacial tension,alteration of wettabili-ty,disjoining pressure,emulsification,prevention of asphaltene flocculation,and catalytic cracking.It also explores the significant application potential of nanoparticle-driven oil displacement materials in various reservoir types,such as high water cut reservoir,low permeability reservoir,tight oil reservoir,and shale oil reservoir.The paper identifies challenges and development prospects for nanoparticles in oil development and provides references and basis for fur-ther research and large-scale application of nanoparticles in enhanced oil recovery.关键词
