中文拼音 [máoguǎnshènliú]
毛管滲流
英文
capillary seepage-
In the first part, it was discussed that the effect of different distribution of shale in shaly sandstones on their permeability based on capillary buddle model
第一部分，在毛細管束模型基礎上，從流體力學理論出發，探討了泥質的不同分佈形式對滲透率的影響。When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer
2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。Finally by means of capillary bundle model, the empirical equation is given to describe the non - darcy filtration features in single facies fluid of low permeability oil reservoirs
最後通過毛管束模型給出了描述低滲透油藏單相流體非達西滲流特徵的經驗方程。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。Typical oil - water relative permeability curve, typical capillary pressure curve, typical pvt correlation of fluvial and delta facies in oil field of china and average value of several reservoir parameter are studied statistically in this paper
