DEVICE FOR DETERMINATION OF PHASE PERMEABILITY OF LIQUID IN SAMPLES OF ROCK CORE BY CENTRIFUGING

摘要

FIELD: measurement technology. SUBSTANCE: device has rock core holder and mixer installed on rock core upper end and made in form of cylinder from highly permeable material. Installed between mixer upper end and base of vessel with two chambers for tested liquids is separating-sealing gasket. Gasket has two noncommunicated hollows which are connected by channels in compliance with chambers containing tested liquids. During centrifuging, under the action of centrifugal forces, one part of liquid passes through rock core sample. Filtering process of sample is observed by accumulated volume of one liquid and by accumulated total volume of two liquids. Device provides for filtering through sample of core of two immiscible liquids during centrifuging. EFFECT: higher efficiency. 3 cl, 2 dwg
