Profile　control　is　utilized　to　redirect　the　injection　water　to　low　permeability　region　where　a　large　amount　of　crude　oil　lies.　Performed　gel　particles　are　the　commonly　used　agent　for　redistributing　water　by　blocking　the　pores　in　high　permeability　region.　But　the　capability　of　deep　penetration　of　performed　gel　particles　is　poor.　Here,　we　formulate　nanoparticle　stabilized　emulsion　(NSE).　The　stability　and　the　effect　of　NSE　on　the　fluid　redirection　in　a　three-dimensional　porous　medium　were　investigated.　By　using　μ-PIV　(particle　image　velocimetry),　it　was　found　that　the　velocity　gradient　of　continuous　fluid　close　to　the　nanoparticle　stabilized　droplets　is　much　higher　than　that　close　to　surfactant　stabilized　droplets.　NSE　behaves　as　solid　particle　in　preferential　seepage　channels,　which　will　decrease　effectively　the　permeability,　thereby　redirecting　the　subsequent　injection　water.　Furthermore,　NSE　shows　high　stability　compared　with　emulsion　stabilized　by　surfactant　in　static　and　dynamic　tests.　In　addition,　water　flooding　tests　also　confirm　that　the　NSE　can　significantly　reduce　the　permeability　of　porous　media　and　redirect　the　fluid　flow.　Our　results　demonstrate　NSE　owns　high　potential　to　act　as　profile　control　agent　in　deep　formation.　©　2021　The　Authors
