Reservoir stability is a key factor in the production of natural gas hydrate (NGH), and also prerequisite to ensuring safe efficient NGH production. However, it has been rarely discussed. To analyze reservoir process by depressurization Shenhu area South China Sea, we established 3D geological model on basis drilling data this area, which was then discretized means nonstructural grid. Then, mathematical coupling four fields (i.e. thermal, hydraulic, solid chemical) considering heat mass...
Gas hydrates are expected to be a potential energy resource with extensive distribution in the permafrost and deep ocean sediments. The marine gas hydrate drilling explorations at Eastern Nankai Trough of Japan revealed variable deposits. reservoirs composed alternating beds sand clay, various conditions permeability, porosity, saturation. This study looks into multiphase flow behaviors layered methane induced by production. Firstly, history matching model incorporating available geological...
The exploitation of natural gas hydrates is in essence the process hydrate dissociation from solid phase into and liquid phases, which a complex problem involving transition gas-water multi-phase flow. Permeability useful parameter for characterizing flow capacity sediments, pore-structure changes caused by make this characterized spatial temporal evolution. Clayey silt sediments form accumulation reservoir South China Sea, whose lithological characteristics (shallow buried deep, poor...
Most hydrate-bearing sediments worldwide exhibit mixed pore- and fracture-filling hydrates. Due to the high exploitation value, pore-filling hydrate production is focus of current research, there a lack systematic research on decomposition hydrates their effects evolution temperature pressure in sediments. If only characteristics are studied while its process ignored, obtained results would be inconsistent with actual situation. Therefore, this study, different dipping angles were studied,...
A facile and efficient synthesis of polysubstituted benzenes has been developed via sequential Michael addition, Knoevenagel condensation nucleophilic cyclization reactions readily available chalcones with active methylene compounds in guanidinium ionic liquids.
Real-time urban expansion information is important for understanding the socio-economic activities and construction policies in areas. Night-time light data, which are available at annual monthly temporal resolutions, can facilitate better analysis of activities. In this study, we proposed a novel calibration method Defense Meteorological Satellite Program's Operational Line-scan System (DMSP/OLS) data based on Rational Function Model (RFM). Stable lit pixels were employed to validate...
Summary So far, a total of 11 hydrate trial production projects have been carried out all over the world, which used single vertical well or horizontal to carry by depressurization method combined with other methods. These traditional methods some limitations: The has small contact area reservoir, and transmission range temperature pressure is limited; therefore, productivity low. can improve from magnitude order; however, there long distance standard commercial marine hydrate. Therefore, it...
Summary Marine-gas-hydrate-drilling exploration at the Eastern Nankai Trough of Japan revealed variable distribution hydrate accumulations, which are composed alternating beds sand, silt, and clay in sediments, with vertically varying porosity, permeability, saturation. The main purposes this work to evaluate gas productivity identify multiphase-flow behavior from sedimentary-complex reservoir by depressurization through a conventional vertical well. We first established history-matching...
Marine natural gas hydrate (NGH) is an important source of energy for the future, while experimental simulations on NGH production are rarely conducted in real marine sediments. This study employed sediments from South China Sea and put upward a method remolding by formation after injecting water into dry sediment with high-pressure methane gas. A 2 °C temperature increase was observed middle layer due to exothermic hydrates. The characteristics different moistures (28.3–73.7%) were...
Natural gas hydrate (NGH) has the huge exploitation potential for clean energy in current world pattern. Its total organic carbon storage is about twice sum of content oil, gas, and coal hence attracts attention world. China carried out some works delineation three deposits whose reserve scale over 100 billion cubic meters, NGH resource abundant. The reservoir South Sea low porosity permeability, unconsolidated, poor cementation, easy to fragment production. On one hand, condition...
The effects of geologic conditions and production methods on gas from hydrate-bearing sediments (HBS) have been widely investigated. reservoir was usually treated as horizontal distribution, whereas the sloping not considered. In fact, most strata gradients because geological structure diagenesis. this study, based currently available data field measurements in Shenhu area South China Sea, formation dip were investigated through depressurization using a well. modeling results indicate that...
