Abstract [1] Gas hydrate saturations were estimated using five different methods in silt and silty clay foraminiferous sediments from drill hole SH2 the South China Sea. derived observed pore water chloride values core samples range 10 to 45% of space at 190–221 m below seafloor (mbsf). resistivity (Rt) wireline logging results are similar 40.5% space. also by P wave velocity obtained during a simplified three-phase equation (STPE) effective medium theory (EMT) models. STPE model (41.0%...
Based on the comprehensive interpretation of cores, loggings and 2D/3D seismic data Shenhu GMGS3 drilling area in northern South China Sea, distribution characteristics, differential accumulation mechanism reservoir forming diffusion type natural gas hydrate with high saturation discovered from clayey silt reservoirs were investigated. The following findings are reached through research: (1) Gas often displays resistivity, low interval transit time, strong bottom-simulating reflectors...
Pore- and fracture-filling gas hydrates were identified from the core samples at several sites during second Guangzhou Marine Geological Survey (GMGS2) expedition. Well logs indicated that hydrate occurred in three distinct layers site GMGS2-08. The saturations calculated well-log data seismic responses for hydrate-bearing layers, especially within middle carbonate layer, poorly known. We estimated using isotropic anisotropic models based on mineral composition of sediments effective medium...
Oxidation of MgB2 under air conditions room temperature to 1000 °C was studied by thermogravimetry, x-ray diffraction and scanning electron microscopy equipped with energy dispersion spectrum. The experiment shows that the obvious oxidation process begins at about 400 becomes very strong when reaches beyond 700 °C. X-ray after for a long time high temperature, most magnesium in MgO. analyses microstructure components show is complex accompanying evaporation boron formation Long MgO whiskers...
Gas hydrate drilling results show that gas has a close relationship with strong bottom-simulating reflectors (BSRs) identified from seismic data in the Baiyun sag, South China Sea. The BSRs observed on profiles at crests of submarine canyons indicate likely existence hydrate. We calculate acoustic impedance using constrained sparse spike inversion (CSSI), interval velocity, and reflection characteristics such as strength, instantaneous frequency, blanking, enhanced to demonstrate presence...
The technique of CO2 capture and separation using charge-modulated sorbent materials holds promise for reducing emissions. Density functional theory with long-range dispersion correction has been used to study the adsorption CO2, H2, CH4, N2 on BC3 nanosheets with/without charge injections. We find that is weakly adsorbed pristine BC3, but injection 3 negative charges (3 e) can change chemical adsorption. Removing results in release without any energy barrier. A high capacity 4.30 × 1014...
