capillary rise
3.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.
5.The contents of ethylene carbonate were analyzed by GC with HP-INNOWAX(crosslinked polyethylene glycol) capillary column as the stationary phase, hydrogen flame ionizatio detector(FID) as detector,two grade program rise temperature as oven temperature. The interstandard method was used in the quantitative analysis.
