Purpose A transmission tower usually experiences bolt loosening under long-term alternating cyclic load, which may lead to collapse of the in extreme operating conditions. The paper aims propose a data-driven identification method for looseness complicated structures based on reduced-order models and numerical simulations perceive evaluate health state operation. Design/methodology/approach equivalent stiffnesses three types joints various scenarios are numerically determined by...
In order to find a short, economically feasible process for chalcopyrite preconcentration and provide reference the of similar copper sulfide ores, particle size characteristics crushed products from high-pressure grinding roller (HPGR) jaw crusher (JC) were analyzed, as well liberation degree fracture chalcopyrite. The float–sink test (FST) was carried out on products, effects two crushing methods FSTs compared. research results show that at same fineness, in HPGR can be enhanced by 14%~18%...
A discrete fracture model for multi-scale flow in large-scale fractured tight oil reservoirs is proposed considering the compressibility of reservoir rock and fluid, non-linear matrix. Validation performed, followed by field application model. The two-point flux-approximation scheme adopted to calculate conductivity, small grids at intersections are eliminated "star-delta" transformation method improve computational stability. fully implicit discretization performed on temporal domain....
Spontaneous imbibition is a critical mechanism for the development of water-wet fractured reservoirs. In order to improve ultimate oil recovery, it important understand change in situ saturation during spontaneous process. this study, experiments two ends open (TEO) are conducted using unconsolidated sand packs. The packs filled with quartz sands three different particle sizes respectively and fully oil-saturated. Nuclear magnetic resonance (NMR) T2 used monitor behind front. For porous...
Numerical modeling methods for dynamic responses of isolated-span transmission lines with uniform and non-uniform ice accretions after whole partial ice-shedding without wind load are proposed experimentally validated by reduced-scale tests. With the method, various structural parameters investigated. The response characteristic extracted to create a dataset, which prediction model jump envelope, maximum transverse swing tension conductor, force on towers is created back-propagation (BP)...
Excessive water production is an enduring problem in the oil industry that has always been unbearable burden on environment and a great damage to ultimate recovery. Gel treatment routinely used for decreasing production. Disproportionate permeability reduction (DPR) natural phenomenon some polymer gels can reduce more than oil. The conformance improvement treatments with DPR effectively cut without substantially reducing productivity fractured reservoirs. At present, there are no widely...
Hydraulic fracturing is essential for efficient developments of low-permeability reservoirs. For these fractured production wells, serious water channeling frequently occurs because the fracture connections to injectors or underlying/lateral aquifers. To address problem, preformed gel treatment typically adopted. One key mechanisms dehydration, which has however not been well understood. This study presents a lab experimental dehydration and its impact on shutoff performance. We carried out...
Summary The process for the enhanced-oil-recovery (EOR) strategic decision is a thorny that depends on proper evaluation, rational understanding of complex relationships, and quantitative assessment multiple categories, including economic considerations, dynamic field production, reservoir numerical simulation, other relevant elements. Using Delphi-AHP-TOPSIS method (Joshi et al. 2011), which combines Delphi method, analytic hierarchy (AHP), technique order preference by similarity to ideal...
The lift, drag and torsional moment coefficients, versus wind attack angle of iced quad bundle conductors in the cases different conductor structure, ice parameters are numerically simulated investigated. With Latin hypercube sampling numerical simulation, points designed datasets created. Set number sub-conductors, angle, spacing, accretion thickness, velocity diameter as input variables, a prediction model for coefficients is created, trained tested based on dataset extra-trees algorithm....
Abstract With the advantages of high sweep efficiency and displacement efficiency, alkaline-surfactant-polymer (ASP) flooding can greatly improve oil recovery by 20%. The microscopic mechanisms have been reported in detail, however, macroscopic 3D fluid flow characteristics still lack enough research. This paper is aimed to study dynamics ASP further clarify distinctions remaining saturation between waterflooding chemical flooding. were examined at both laboratory numerical scale. A sandpack...
Injection conformance reversion commonly observed during polymer flooding in offshore heterogeneous heavy-oil reservoirs weakens the volumetric sweep of solution and compromises its EOR results. To investigate mechanisms impact factors, one mathematical model to predicate injection behavior is constructed for based on Buckley-Leverett function. The different suction capability each layer results distinct change law flow resistance force, which turn reacts upon creates dynamic redistribution...
In order to rationalize the development and utilization of wall rock discarded during rare earth mining, chemical analysis, inductively coupled plasma-atomic emission spectroscopy, X-ray diffraction artificial panning, optical microscope mineral liberation analysis energy-dispersive spectroscopy were used study process mineralogy rock. The results show that main useful elements in iron, light elements, fluorine niobium. Iron was mainly occurrence as magnetic iron magnetite, bastnaesite...
