polarity gradient 中文意思是什麼

polarity gradient 解釋
極性梯度
  • polarity : n. 1. 【物理學】(分)極性,磁性引力;(光的)偏極;極體;【數學】配極(變換);【生物學】(莖與根的)反向性,極性。2. (性格的)正反對。3. (思想、感情等的)歸向,傾向。
  • 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。
