viscosity gradient 解釋
粘度梯度
  • viscosity : n. 黏性；黏（滯）度；【物理學】黏滯性。
  • gradient : adj. 1. 傾斜的。2. 【動物；動物學】步行的，能步行的。n. 1. 〈英國〉（道路的）傾斜度，坡度，坡路。2. 【物理學】梯度，陡度，（溫度、氣壓等的）變化率，梯度變化曲線。
  1. The boundary layer can indicate the comprehensive influences of oil reservoirs, the physical properties ( reservoir porosity, permeability, fluid viscosity and its composition ) of inside fluids and development conditions such as pressure gradient : the layer thickness reduces with the rise of capillary radius ; when capillary radius is fixed, the thickness increases with viscosity rise ; the more polarity composition content is, the more obvious the absorption, the thicker the boundary layer, more and more obvious the characteristics of non - darcy filtration

    邊界層反映了儲層、流體物性條件（儲層孔隙度、滲透率、流體粘度、組分）和開發條件（壓力梯度）的綜合影響，認為邊界層厚度隨著毛管半徑的增大而減小；在毛管半徑相同的情況下，邊界層厚度隨壓力梯度的增大而減小，最後達到一個臨界值；毛管半徑一定時，邊界層厚度隨粘度增加而增大；極性組分含量越大，吸附越明顯，邊界層厚度越大；邊界層厚度越大，非達西滲流特徵越明顯。
  2. Through large amount of lab experiments, the relation of oil boundary layer thickness with capillary radius, pressure gradient, fluid viscosity and its composition has been discussed

    摘要通過大量的室內實驗，探討了原油邊界層厚度與毛管半徑、壓力梯度、流體粘度和組分的關系。
  3. The maim factors affecting the velocity profiles are the viscosity near the bed, particle grid resistance and the density gradient

    影響流速分佈的主要因素有底部粘度、顆粒格柵阻尼和密度梯度。
