Investigation of bank replacing speed influence on coefficient of oil displacement from the porous medium
R.A.AhmedovOn specially designed installation which imitates layer conditions bank replacement speed in porous medium influence on oil displacement coefficient has been studied. During the investigation have been studied 14 models of liquid consisting of oils with newton and non-newton properties with hard formation and alkali waters in different correlations. In the article are shown the results of the liquids rheological properties investigation. Liquids displacement from the layer model with rock porosity value 0.28 and permeability 0.052 mkm2 was carried out via nanobank in (36).10-2 m/hour. During the investigation has been revealed that in reviewed conditions the best result of liquid displacement coefficient from porous medium is achieved in bank displacement speed equal to 4 . 10-2m. It has been defined that in other equal conditions liquid displacement coefficient consisting of oil mixture and alkali formation water is for 810% more than in liquid mixture displacement, consisting of oil and hard layer waters.
