METHOD FOR INVESTIGATING EFFECT OF SURFACE PROPERTIES OF POROUS MEDIUM ON FILTRATION OF OIL

摘要

Usage: in oil, in particular in the modeling process oil filtration in the laboratory. Summary of the Invention; create a model of the formation using as the porous medium quartz sand, crushed natural core, silica et al., the porous medium is filled with oil and is carried out expulsion therefrom of oil with an inert gas such as nitrogen, in the direction opposite to saturation, then the model formation with residual oil was cut into elements and making t qualitative analysis and quantitative determination of the distribution of residual oil in the filtering process. 1 ZP f ly-1-yl.
