Natural gas hydrate is widely spread in marine environments around the world. It has great energy potential due to its high methane content. High-precision exploration and evaluation of still face challenges as it affected by complex reservoir control mechanisms distribution characteristics. Resistivity used geophysical logging theoretical research on hydrate-bearing reservoirs utilizing sensitivity electrical response. In this paper, based examination global occurrences, resistivity results...
With the development of dye industry, treatment wastewater needs to be solved urgently. In this work, conventional ozonation and peroxone (O3/H2O2) processes were used treat Direct Red 80 wastewater, influence relevant factors efficiency was analyzed by using physicochemical methods including UV-visible absorption spectrum, three-dimensional fluorescence spectrum ion chromatography. Through analysis oxidation mechanism under ozone treatment, a possible degradation pathway deduced. The...
High-resolution (HR) digital bathymetric models (DBMs) are essential for marine science studies. Currently, there very few areas where detailed seafloor surveys have been conducted, which is insufficient to provide insight into the geological and oceanographic processes of our planet. In recent years, HR DBMs successfully reconstructed from low-resolution (LR) using deep learning. However, DBM reconstruction has high uncertainties due complexity topography. Meanwhile, learning-based methods...
SUMMARY The in situ reservoir status monitoring plays a critical role natural gas hydrate resource production. Considering the complexity of field environment, simulation framework for hydrates with cross-hole electrical resistivity tomography (CHERT) was developed to monitor distribution during formation and dissociation. study comprised both numerical physical experiments. optimal CHERT array designed through experiment. effect applying verified experiment (a high-resistivity medium...
As a new energy source, gas hydrates have attracted worldwide attention, but their exploration and development face enormous challenges. Thus, it has become increasingly crucial to identify hydrate distribution accurately. Electrical resistivity tomography (ERT) can be used detect the of deposits. An ERT inversion network (ERTInvNet) based on deep neural (DNN) is proposed, with strong learning memory capabilities solve nonlinear problem. 160,000 samples about are generated by numerical...
The induced polarization (IP) method plays an important role in the detection of seafloor polymetallic sulfide deposits. Numerical simulations based on Poisson–Nernst–Planck equation and Maxwell were performed. effects mineralized structures IP electrical conductivity properties sulfide-bearing rocks investigated. results show that total chargeability increases linearly as volume content disseminated metal sulfides when is below 20%. However, nonlinearly with increasing vein massive 30%....
In light of the difficulty solid-liquid separation waste PEM drilling fluid in Bohai oilfield, constructing an inorganic-organic flocculation system is proposed and processing method destabilization technology optimized. The biggest influence factor on process was determined by designing orthogonal test. mechanism researched through single optimization, combined with zeta potential particle size distribution results showed that most significant factors affecting were dosage inorganic...
Currently, there is insufficient knowledge on the development of China's low-permeability gas reservoirs under ultrahigh-temperature and high-pressure conditions; furthermore, actual process difficult has high technical demands. For example, Ledong block in South China Sea a typical reservoir characterized using ultrahigh temperature (190 °C), pressure (90 MPa), water production, low permeability (less than 1 mD). However, it to determine factors influencing its production capacity,...
