In this paper, we use the parallel open source code parallelSPHysics based on weakly compressible Smoothed Particle Hydrodynamics (WCSPH) approach to study a spillway flow over stepped stairs. SPH is robust mesh-free particle modelling technique and has great potential in treating free surfaces hydraulics. A laboratory experiment carried out for different discharges step geometries. The physical model constructed from prototype reservoir dam practical field. During experiment, discharge weir...
Deep-water turbidite channels have attracted much attention as a focused issue in petroleum exploration and development. Extensive studies been performed on the architecture of channels, most researches their geometric shapes, sedimentary processes controlling factors. However, little has paid to distribution patterns, laws quantitative composite sand bodies channels. Taken one slope area Niger Delta Basin an example, this study conducted semi-quantitative analysis based cores, well logging...
Coalbed methane (CBM) is strongly adsorbed to coal, with over 95% existing in an state, making it difficult effectively extract using traditional borehole drainage or gas methods, particularly low permeability and under pressure CBM reservoirs. This study proposes thermal-enhanced extraction by superheated water injection. Laboratory experiments were first conducted examine deformation temperature change during coal adsorption/desorption, quantify adsorption heat at (room temperature–150 °C)...
Abstract Coal bed methane (CBM) significantly contributes to unconventional energy resources. With the development of drilling technology, multi-branched horizontal wells (MBHWs) have been put into exploitation CBM. In this paper, a semi-analytical mathematical model is introduced study production characteristics MBHWs in composite CBM reservoir. Stress sensitivity, reservoir, and complex seepage mechanisms (desorption, diffusion, Darcy flow) are taken consideration. Through Pedrosa...
Abstract Pre‐stack reverse time migration (RTM) for rugged topography is a very useful tool seismic imaging in the areas with strong relief on surface and complex subsurface structures. In this paper, we illustrate implementation process of RTM topography. To deal difficulty dealing free boundary condition finite difference method, employ simplified which could avoid abundant logical judgment. On basis, use Graphic Processing Unit (GPU) architecture to accelerate get an order magnitude...
摘要:
The pyrE gene, encoding orotate phosphoribosyltransferase (OPRTase), was cloned by nested PCR and colony blotting from Corynebacterium ammoniagenes ATCC 6872, which is widely used in nucleotide production. Sequence analysis shows that there a lack of an important conserved lysine (Lys 73 Salmonella enterica serovar Typhimurium OPRTase) the C. OPRTase. This has been considered to contribute initiation catalysis. enzyme overexpressed purified recombinant Escherichia coli strain. molecular mass...
Without requiring objects to carry any transceiver, device-free based object tracking provides a promising solution for many localization and systems monitor non-cooperative such as intruders. However, existing solutions mainly use sensors active RFID tags, which are much more expensive compared passive tags. In this paper, we propose novel motion detection method using named Twins. The leverages newly observed phenomenon called critical state caused by interference among We contribute both...
The phytoplankton population of Qionghai Lake was surveyed in December 2015, March 2016, June September and 2017. A total 196 species (including varieties) belonging to 77 genera 7 phyla were identified. communities dominated by Chlorophyta diatoms, there significant differences across the five sampling sites. abundance, which ranged between 13.85 × 104 335.54 cells·L−1, significantly higher spring summer than autumn winter. Chlorella sp. Cyclotella dominant populations, their dominance...
Permeability rebound and recovery are pivotal in determining the efficacy of coalbed methane (CBM) extraction impact superheated water injection during thermally enhanced CBM extraction. Existing research predominantly focuses on roles effective stress desorption shrinkage, often neglecting critical influence temperature. Therefore, our study introduces a mathematical model incorporating heat-fluid–solid coupling permeability evolution considering temperature variations. The was used to...
Es2 member reservoir of Guojuzi sag is located in the east Bohai Bay Basin China, mainly composed beach bar sediments, which are thin and irregular distribution. Conventional post-stack seismic attributes cannot predict effectively, while pre-stack inversion also has difficulties application for low SNR data. A number amplitude preserved processes taken to obtain high Then AVA simultaneous adopted achieve elastic parameters. Well log analysis shows that µρ lower Vp/Vs can be good indicators...
Remanufacturing is one of the most effective strategies to achieve sustainable manufacturing and restore performance end-of-life products. However, lack an cleaning method clean carbonaceous deposits severely hampers remanufacturing engines. To explore appropriate method, it necessary first study characterization deposits. A broad range analyses including X-ray fluorescence spectrometry, thermogravimetric analysis, 1H-nuclear magnetic resonance study, diffraction scanning electron microscopy...
