Digital core simulation technology, as an emerging numerical method, has gradually come to play a significant role in the study of petrophysical properties. By using this influence micro factors on seepage properties reservoir rock is taken into consideration, making up shortcomings traditional physical experiment. Three-dimensional images are reconstructed by computed tomography scanning technique. Different sizes sub-region were simulated three methods including direct computation...
Summary Gas condensate is stored in multiscale pores, fractures, and vugs within geological formations. Confinement these structures significantly influences the phase behavior of gas condensate, rendering it challenging to characterize through conventional bulk pressure/volume/temperature (PVT) measurements. In this study, we used microfluidics in-situ computed tomography (CT) scanning directly measure upper dewpoint gas/oil ratio porous media during depressurization. We two microfluidic...
Primary and secondary oil recovery are the main early-stage production methods of carbonate reservoirs. However, its intrinsic complex pore structure causes reduction during process depletion production. The distribution brine varies in space water flooding. core to solve problems is figure out dynamic evolution remaining oil. In this work, three heterogeneous marine samples were made carry injection experiments using real-time computed tomography scanning. saturated those after injecting 3,...
With the development of gas-condensate reservoirs, phase behavior gas condensate undergoes continuous changes. The in PVT cylinders is different from that fractured-vuggy reservoirs because multiscale pore structures can affect behavior. By vuggy, we mean formation a reservoir contains cavity structures. To elucidate influence porous media on condensate, microfluidic chip and carbonate sample were prepared for pressure depletion experiments. during depressurization was observed via...
Storing protein formulations in the frozen state typically improves stability during long-term storage as a drug substance or product. The minimizes chemical degradation and physical instability. However, is not an optimal condition for glass vial itself. A significant issue was observed when small, flake-like pieces of particles (lamellae) appeared vials containing thawed occurrence freeze-thaw results product rejection potentially, adverse events. In recent years, flakes due to...
The phase behavior of gas condensate in reservoir formations differs from that pressure–volume–temperature (PVT) cells because it is influenced by porous media the formations. Sandstone was used as a sample to investigate influence on condensate. pore structure first analyzed using computed tomography (CT) scanning, digital core technology, and network model. sandstone then saturated with for pressure depletion experiment. After each pressure-depletion state stable, real-time CT scanning...
Abstract Porous media were simplified as a series of constricted capillary tubes related to particle size and arrangement, the distribution pore diameter volume factor in cell was calculated. Based on mechanics theory, models threshold pressure gradient (TPG) for porous obtained that provided comprehensive consideration structure, gas–liquid ratio (GLR), interfacial tension, deformation characteristics bubbles throat pore. Moreover, experiments TPG foams at steady state investigated. The...
Abstract Energy consumption in the world increases 5.6% every year, and alternative resources like shale gas, coal-bed methane (CBM), tar sand, so on are strongly needed. Shale gas is an unconventional natural of enormous potential. Abundant resides form adsorption gas. Desorption important mechanism power source reservoir development. Based features reservoirs, adsorption/desorption mechanisms, their influencing factors, high-temperature mixture flooding proposed this article. Combining...
AbstractThe dew point pressure can be obtained by conventional condensate gas phase test in PVT cylinders. However, reservoirs, the fluid interacts with fractured-vuggy porous media, which makes depletion process of pores, fractures or vugs different from that cylinder. In order to study mechanism this difference, three experimental models were made carry out production experiment. The results showed existence fracture-vuggy media would affect process. and increased 26.2 MPa 26.6 decreased...
In this work, we derived a mathematical model for spontaneous imbibition in Y-shaped branching network model. The classic Lucas–Washburn equation was used modeling the process occurring Y-shape Then, Newtonian fluid’s to reveal relationship between dimensionless time and length ratio, radius wetting strength. adopted compare with that of capillary bundle Different ratios were considered adjacent two-stage channels, different wettabilities branches. optimal strength calculated under condition...
Abstract The influence of channeling on viscous fingering instability CO 2 miscible displacement is studied in the paper. Due to not easily observed porous media, used simplify instability. We adopted nonlinear simulation investigate development during Newtonian fluids a channel by fluids, and different Pe viscosity ratio R was studied. Under homogeneous conditions, when same, larger is, more obvious convection process earlier occurs, shorter time for finger break through right boundary is....
Abstract Reservoir bubble point pressure and gas-oil ratio are important parameters for the scheme design of oilfield development calculation reservoir elastic reserves. However, their change laws complex. At present, there few studies on mechanism gas oil changing with depth, which is an urgent problem to be solved in exploration fields. This study focuses variation depth under different tectonic movement conditions process formation complex structural reservoirs. When buried small, crude...
