Capillary pressure and relative permeability are important parameters in geothermal reservoir engineering. It is essential to represent capillary pressure curves mathematically in an appropriate way. The Brooks-Corey capillary pressure model has been accepted widely, however it has been found that the Brooks-Corey model cannot represent capillary pressure curves of The Geysers rock samples. In ...

Abstract The release of dissolved gas during the development gas-bearing tight oil reservoirs has a great influence on effect development. In this article, high-pressure mercury intrusion experiment was carried out in cores from different regions and lithologies Ordos Basin Sichuan Basin. objectives are to study microscopic characteristics porous throat structure these analyze flow resistance l...

The objective of this work was to develop a fast and significant method for the determination of the intraparticulate pore size distribution of microspheres. Poly(lactide-co-glycolide) (PLGA) microspheres prepared with a solvent extraction/evaporation process were studied. From the envelope and the skeletal volume of the microspheres the porosity was calculated. The skeletal volume was determin...

Lower Permian Fengcheng Formation is considered to be a high-quality alkaline lacustrine shale oil resource in the Junggar Basin, NW China. Based on core and thin section observation, X-ray diffraction, scanning electron microscope, low-pressure N 2 adsorption, high-pressure mercury intrusion porosimetry, different lithofacies, pore structures were examined. According mineral composition, shale...

Abstract Loop heat pipe, carried out by liquid-gas phase transition, has been attracted as an efficient management device in high-heat-flux, long-distance and anti-gravity situations. The capillary pressure provided the porous wick evaporator drives circulation for working liquid, affecting exchange efficiency loop pipes directly. In this work, bi-porous Ti 3 AlC 2 was produced reaction sinteri...

Mercury-contaminated chemical wastewater of a mercury cell chloralkali plant was cleaned on site by a technical-scale bioremediation system. Microbial mercury reduction of soluble Hg(II) to precipitating Hg(0) decreased the mercury load of the wastewater during its flow through the bioremediation system by up to 99%. The system consisted of a packed-bed bioreactor, where most of the wastewater'...

Abstract Mobility is the main factor restricting production of tight oil. In order to explore influence pore throat structure and fluid seepage on mobility, six sandstone samples are selected by high-pressure mercury intrusion, nuclear magnetic resonance, water driving oil experiments, oil-water relative permeability experiments discuss multiphases mobility The results indicate that with increa...

In the past decades, gas discharge lamps have gained widespread use in industrial applications. Due to their unique design properties concerning spectral, electrical and geometrical features, all types of gas discharge lamps can been found in technical applications. Mercury based lamps are the workhorses in many applications upgraded by their relatives, the metal halide versions. The low and me...
