Conventional hydrocyclones (CHCs) exhibit limited effectiveness in separating fine oil droplets from produced fluids, constraining overall oil-water separation efficiency. Mini (MHCs) with smaller main diameter can further enhance the efficiency of droplets. This study constructs a two-stage series system using two individual MHCs. Simulations were conducted to investigate effects split ratio, water content, and droplet size on performance. The adaptability these parameters was thereby...
To overcome the disadvantages of traditional downhole communication methods, a vibration wave technique is proposed, and system developed. This has been verified by field test applied to separated layer water injection. It shown theoretical research that transmission through tubing casing appears as alternate distribution pass-band stop-band. According that, multi-baseband strategy formulated. The on-off keying modulation Manchester encoding scheme are used load control information into...
Abstract Reliably estimating reservoir parameters is the final target in characterisation. Conventionally, characters from seismic inversion implemented by indirect approaches. The estimation of inverted elastic parameters, however, will produce large bias due to propagation errors procedure inversion. Therefore, directly obtaining prestack data through a rock-physical model and amplitude variation with offset (AVO) proposed. A generalised AVO equation terms oil-porosity (OP), sand indicator...
Due to the mismatch between quarter-wave plate and wavelength of light source, circularly polarized field photoelastic stress analysis method has an impact on measurement phase delay direction angle. In particular, is inaccurate for weakly stressed samples with delays less than a quarter-wavelength. this paper, we first give calculating value δ, which requires only one air calibration without prior parameters other equipment. We then introduce δ into correction process delay, derive...
To enhance the separation efficiency of downhole oil–water hydrocyclones in co-produced wells, an axial center-piercing hydrocyclone structure is proposed. A mathematical relationship model between structural parameters and constructed based on response surface methodology. The numerical simulation method employed to analyze both unoptimized optimized structures, their performances are simulated under identical operational conditions. results indicate that optimal parameter values as...
To find a convenient and non-destructive way to detect the water stress status of maize plant, hyperspectral technology was used leaf content (LWC) in this paper. Experiments were conducted on at seedling stage Beijing, China. Firstly, images 85 plant leaves obtained. remove redundant information, two methods for dimensionality reduction, which are principal component analysis (PCA) kullback-leibler divergence (KLD) methods, resulting 10 6 wavebands, respectively. These wavebands then...
Recovering MR images from partially acquired k-space data can reduce scan time, leading to significant applications. Deep learning approaches have been proposed train neural networks using under-sampled and full-sampled image pairs in a supervised manner. However, these models usually poor generalizability when deployed acquisitions different the training datasets. Here, we propose an unsupervised Denoising Diffusion Probabilistic Model (DDPM) capable of not only generating random...
This paper extends our recent work (Zhang et al., “Certain problems in constrained cubic quasicrystals: General solutions and infinite-space Green’s functions”, Int J Solids Struct, 2022, 111830) to the corresponding half-space with different boundary conditions. The analytical of generalized Lorentz problem, Mindlin two mixed problems, are directly derived by using Phan-Thien method, general solutions, functions. Unique phenomena occur stress fields, which show significant effect on...
Abstract The CFD-DEM coupling calculation method is used to study and analyse the influence of different particle sizes on motion behaviour when they collide in hydrocyclone. results show that particles move hydrocyclone, hardly with inner wall collision position mainly concentrated 140mm-80mm range When collide, are suddenly subjected contact reaction caused by collision, trajectory will be adjusted from following fluid streamline circling at a certain longitudinal position, size increases...
<p indent=0mm>Under the guidance of President Xi Jinping’s strategic thinking about how to establish archaeological science with Chinese characters, style and fashion, National Natural Science Foundation China (NSFC) attaches great importance science, seeks continuously deepen reform its fundamental management system. A new round disciplines’ application code optimization was launched in April 2020. Under first-level discipline “science geography (D01)”, a second-level “evolution geographic...
Spatial self-phase modulation (SSPM) is widely used to characterize the nonlinear refractive index of two-dimensional layered materials and design passive photonic devices. In this work, we investigate SSPM phenomena black phosphorus dispersed in agarose solid under excitation on-axis off-axis integer half-integer vortex beams. It found that with increase distance Gaussian beam, pattern far-field self-diffraction intensity gradually breaks from initial ring finally evolves into a tail...
The compressive strength of bricks used in masonry structures is difficult to deterministically evaluate because its uncertain nature. It realistic model the a probability manner. Compressive tests for were conducted, and then was proposed through Bayesian inference based on test results. appropriately represented uncertainty inherent brick strength, can be draw characteristic values structural design or assessment.
Ancient wood structure usually has good anti-seismic performance because of structural characteristics. Mortise joint and tenon component parts the node can be very energy dissipation mitigate effects earthquake damage at time seismic action. Column foot foundation effectively reduce response with friction-sliding. It give clear status evaluation from perspective applicability to protecting ancient timber structures which is great importance protection.
