A simple miniature magnetic-field probe for near-field measurements in 9-kHz-20-GHz bandwidth, which is applied to highspeed circuits, has been proposed and manufactured. The magneticfield built on a four-layer printed circuit board (PCB) using high-performance low-loss Rogers material (ε <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> = 3.48 tan δ 0.0037). Electric field coupling can be suppressed by PCB shielding structure of the...
Capillary number theory is very important for chemical flooding enhanced oil recovery. The difference between microscopic capillary and the one easy to confuse. After decades of development, great progress has been made in it but sometimes incorrect application EOR. was based on tube bundles Darcy’s law hypothesis, this should always be kept mind when used flow low permeability porous media often shows obvious non-Darcy effects, which beyond law. Experiments data from ASP SP showed that...
In low oil price era, it seems that ASP flooding has little market. However, progress in China shows is good technology to help companies thrive and make profit. Since 2014, entered industrial application Daqing oilfield. production 2015 3.5 million ton, 9% of the oilfield’s total There are 22 blocks Daqing, containing 7231 wells 3 new 2016. Obviously, more being carried out. Another large field test high temperature (80°C) Henan oilfield got staged incremental recovery 7.7%. Latest theory...
In this paper, a miniature electric field probe with an ultrawideband of 9 kHz-20 GHz is proposed, fabricated, and tested. The fabricated on four-layer printed circuit board using high-performance low-loss Rogers material (ε <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> = 3.48 tanδ 0.0037). Coax-thru-hole via array used to control the signal impedance achieve 50 Ω match over whole working band, reducing harmful influence probe's...
Abstract After decades of development, great progress has been made in capillary number theory and it important but often incorrect application EOR. Investigation into on some misuse helps to make better use it. Latest concerning with its chemical EOR is reviewed by studying the experiments data checking model hypothesis. Classic Capillary Desaturation Curves (CDC) are summarized new CDC introduced. Typical classical showed larger lead lower residual oil saturation when increased a certain...
Radiation is a vital mechanism affecting electromagnetic interference (EMI), noise control, and performance optimization in today's electronic designs. Due to tight compatibility standards, it becomes increasingly important diagnosis the radiation hot spot process before mitigation applied. In this paper, characteristic mode analysis has been implemented together with integral equation based numerical methods identify spots for EMI radiation. During process, current split into radiating...
The carbon-supported Au hollow nanosphere (HNAu/C) composite electrocatalyst was prepared by sacrificial templates at room temperature. catalytic activity of HNAu/C and solid nanoparticles (SNAu/C) for BH4− were compared. Cyclic voltammogram (CV) results showed that the catalysts exhibit a higher electro-oxidation. A simple direct borohydride−hydrogen peroxide fuel cell using as anode SNAu/C cathode fabricated. effect sodium hydroxide borohydride concentrations performance studied. It found...
The disaster of coal spontaneous combustion mainly occurs in a concealed oxygen-poor environment the underground mine. formation law hydrocarbon index gases can accurately reflect degree combustion. In this paper, influence on was investigated by program heating experiment different environments. results reveal that rising tendency alkane gas volume fraction be reduced increase degree. Olefin predict more reliably than environment. As optimal predictive environment, ratios olefins to alkanes...
Abstract Compared with other EOR technique like gas flooding, chemical and thermal production in heavy oil, the prominent advantages MEOR has environment-friendliness lowest cost. various applications not only sandstone but also carbonate reservoirs, light oil reservoirs as well reservoirs. This paper mainly reviewed progress laboratory studies field tests including six big successful China. Present focus on been changed from qualitative analysis to quantitative characterization, high-tech...
Dipole moment model is widely used to represent real noise source estimate near field coupling between and the victim antenna. However, direct full wave simulation of large number dipole often very time-consuming. Also, another set needed if parameters change. A more scalable approach needed. In this paper, a transfer function based proposed solve issue. The method only needs one-time simulation. results obtained from can be reused for other cases same antenna structure used. will use...
This paper is focused on the construction of a conducted-emission model for switched-mode power supply (SMPS). First, total voltage source extracted by measurement. Second, coupling path between aggressor and victim characterized both simulation Finally, coupled noise to with respect can be obtained calculation. Both results match well measurement result, which validates robustness constructed model.
The variability of crosstalk due to changes in differential and ground via configurations is studied this paper. polynomial-chaos method the response surface are adopted mathematically model variability. One goal work exploit obtained models locate optimal that both meets performance requirement remains robust geometry variations manufacturing tolerances. Both methods correlate well with simulations show great capabilities practical applications for optimization sensitivity analysis. other...
