Surfactants synergized viscoelastic polymers can effectively balance the thickening and injectivity ability of composite system improve its enhanced oil recovery (EOR) effect. This work systematically studies impact concentration, compounding methods with surfactants, surfactant types, salt concentrations on rheological behavior modified carboxymethyl cellulose (mCMC) based shear properties. Then, experiments above solutions were carried out to compare differences in properties solution...
Polymer microsphere transport in porous media widely appears oil field development. However, the migration and plugging mechanisms of microspheres at pore-throat scale need further study. In this paper, four one reservoir etching models were designed to simulate pore throat distribution with different heterogeneities real structures, respectively. The matching relationship, dynamic behavior, enhanced recovery (EOR) clarified based on injectivity displacement experiments. results show that...
This study carried out interfacial tension (IFT) testing, sand surface element analysis and scanning electron microscope imaging, rock–oil–emulsification system interaction microstructure, droplet size distribution, stability of oil in water (O/W) emulsion to clarify the porous media flooding mechanism a hydrophilic nano-SiO2 enhanced emulsification system. The results show that by adding small amount (0.01 wt. %) into an anionic surfactant fatty alcohol polyoxyethylene ether sodium...
Chemical flooding agents, especially surfactant-based oil have been widely studied due to their excellent emulsification ability. Nevertheless, there are many evaluation methods for chemical and the focus of each test is different. How combine routine testing with reservoir conditions an urgent problem be solved. In this study, different kinds agents were evaluated interfacial tension (IFT), minimum speed, state, droplet size distribution, viscoelasticity, apparent viscosity in porous media,...
Chemical flooding is a very important method to the efficient development of heavy oil reservoir. A clear understanding relationship between emulsification characteristics during chemical and test methods that current used evaluate properties agent can be useful for oilfields oil. In this study, oil–water interfacial tension (IFT) in water (O/W) emulsion (emulsification state, droplet size, viscoelasticity, stability) formed by six agents at different concentration are tested. Then, combined...
The carbonate reservoir plays a pivotal role in conventional oil and gas reservoirs. However, due to limited knowledge of fluid flow characteristics fractured-vuggy formations (vuggy means small medium-sized cavity inside rock), high efficiency development remains challenging. In this study, the similarity principle is utilized design two-dimensional visual model based on geological data injection-production M Oilfield. To investigate oil–water flow, interface, residual distribution,...
The emulsification of heavy oil and water into a W/O emulsion would increase the viscosity reduce mobility oil. As we know, addition reducer such as water-soluble surfactants could change status improve Although up to 90% reduction be achieved in laboratory experiments, field improvement recovery is not satisfactory with reducer. Actually, it related difference mixing process reducer, water, between lab experiments subsurface flow formation. significantly affected by temperature...
Abstract Hydrochar is an urban soil amender that supports plant growth on slopes. It a biomass-derived carbon-rich material produced by the hydrothermal carbonation process; thus, it has different pore structure from biochar pyrolysis. The effects of hydrochar hydraulic properties unsaturated compacted soils and underlying pore-level soil-hydrochar interaction mechanisms are unclear. In this study, silty-clay sand was amended grass-derived hydrochars at two carbonisation temperatures (180...
Active substances such as asphaltene and resin in heavy oil tend to absorb on the oil–water interface. Thus, water would easily emulsify into water-in-oil (W/O) emulsion under shared action of formation porous media. Emulsification produced fluid during recovery is important for accurately calculating recovery. Studies properties can effectively forecast reservoir production dynamics. Therefore, water/steam flooding experiments at different permeabilities, viscosity, varying temperature were...
CO2 flooding is a favorable technical means for the efficient development of low-permeability reservoirs, and it can also contribute to realization net-zero emissions. However, due unfavorable viscosity ratio gravity overriding effect, channeling will inevitably occur, seriously affecting its storage displacement effects. This paper conducts systematic study on application polymer-assisted in reservoirs. Firstly, polymer agent suitable reservoirs optimized through viscosity-increasing,...
