Abstract Tight gas sandstone samples are imaged at high resolution industrial X-ray computed tomography (ICT) systems to provide a three-dimensional quantitative characterization of the fracture geometries. Fracture networks quantitatively analyzed using combination 2-D slice analysis and 3-D visualization counting. The core firstly scanned produce grayscale slices, corresponding area, length, aperture porosity as well density were measured. Then slices stacked create complete image...
This paper describes an experimental study of starvation and flow behavior in grease-lubricated elastohydrodynamic contact. Rolling tests were conducted with four grease samples different thickeners base oils a conventional ball-on-disk test rig. The EHL central film thickness was determined SLIM, the Spacer Layer Imaging Method, around conjunction pattern on track disk specimen observed CCD cameras. included some thickener deposited corrugated fingerlike outward from center track. It found...
Vibrations have attracted much attention as an effective method for enhancing heat transfer in pulsating pipes (PHPs). This study mainly investigates and explores the effects of local low-frequency vibrations on starting-up characteristics a PHP. The temperature average temperatures along evaporation section pipe were experimentally scrutinized, with thermal performance, under evaporation, condensation adiabatic sections, respectively. following important conclusions can be derived by...
This study mainly experimentally investigates and explores the effects of local low-frequency vibrations on starting-up heat transfer characteristics pulsating pipe. A micro motors with vibration frequency 200 Hz were imposed external surface evaporation, condensation adiabatic section pipe, respectively, temperature average temperatures along evaporation as well thermal performances vibrating pipe scrutinized under different positions. The following important conclusions can be achieved by...
Abstract For water-flooding oilfields, both indoor experiments and mine field practices have confirmed that long-term water flooding can change physical properties, wettability, fluid parameters. The comprehensive performance of these changes is the relative permeability curve oil dynamically. Usually, numerical simulation does not consider reservoir which will cause mismatch history matching. This error especially obvious in high water-cut period. It further affected understanding remaining...
Condensate gas is a transition fluid between oil and gas, which sensitive to the reservoir temperature pressure. In condensate reservoir, especially in moderate-giant one, composition often varies with depth. This phenomenon has important influences on development. Anisothermal compositional gradient theory used analyze main factors influencing distribution understand basic regularities of variation Geothermal gradient, composition, temperature, pressure will affect geothermal most direct...
A new simulation method for hydraulic fracturing-assisted depressurization development of HBLs is developed, in which the mass transfers matrix-matrix, fracture-matrix, and fracture-fracture are obtained based on discrete fracture models, a PEBI unstructured grid adopted to achieve accurate characterization complex shapes, while overall number equations be solved greatly reduced by adaptive refinement. Then, numerical model was established geological parameters Class III South China Sea,...
The heat transfer enhancement of a jet issued from the circular cylinder placed in three-dimensional microchannel at low Reynolds numbers were studied systematically by using numerical simulation. effects on thermal efficiency evaluated varying injection ratios (I) and angles (θ). physical mechanism was revealed through analyses vorticity dynamic temperature field. results showed that proportional to ratio Re = 100 200. However, 300, did not increase monotonically with ratio, local maximum...
Free-piston Stirling power generating system is a complex coupling of thermo-mechanical-electrical, the thermo-electrical efficiency which affected by many factors. The effect critical parameters core components on main focus, including regenerator porosity and change wire screen diameter system, changes flow resistance coefficient efficiency, clearance between piston air cylinder heater transfer to improve efficiency.
Threshold pressure gradient, gas slippage, and stress sensitivity have important effects on the production of a tight reservoir. But previous studies only focused one or two these effects. In this study, mathematical model considering three was established to describe transport in dual-porosity are simultaneously considered velocity term continuity equation which is mainly different from research results. The partial differential definite solution condition discretized by central difference...
