“…With the development of microfluidic technology, the interfacial elasticity of emulsion droplets can also be detected by microfluidic methods, 30 which will rapidly develop in situ measurement aspects. Due to the complexity of the interfacial rheological properties of emulsion droplets and the pore throat structure in reservoirs, emulsion droplets have special rheological characteristics in porous media, such as viscoelastic deformation characteristics, 31 Haines instabilities, 32 the Marangoni effect at interfaces of emulsion droplets, 33,34 and vortex flow characteristics inside droplets 35,36 . Usually, asphaltene, clay particles and polymers adsorb on the surface of crude oil to form solid particle‐stabilized emulsions during chemical flooding; they are referred to as Pickering emulsions 37,38 .…”
