Abstract.It was first revealed that the cause of the manifestation of the anomalous properties of viscous and anomalous liquids, and in particular water, kerosene, Newtonian and non-Newtonian oils in cracks and equivalent super-permeable porous media, is the discovered new microcrack-liquid effect. The “microcrack-liquid” effect found by the conducted studies will be taken into account in the practice of oil production when extracting oil from fractured formations and with increasing oil recovery coefficient. If measures are developed, but the weakening or elimination of the found effect “microcrack-liquid” in the practice of oil production when extracting oil from fractured formations will lead to an increase in oil recovery coefficient.
Keywords: oil recovery coefficient, microcrack opening, microcrack-fluid “microcrack-liquid” effect.
