APPARATUS FOR GENERATING AND ANALYSING CO2 FOAM IN THE CONDITIONS OF OIL RESERVOIR

摘要

The present invention relates to an apparatus for generating and analyzing CO2 foam in a reservoir condition, which comprises a foam generating unit (110) generating carbon dioxide foam by receiving a surfactant solution and liquid carbon dioxide and discharging the carbon dioxide foam; a pump (120) for supplying the liquid carbon dioxide from a CO2 tank (121) containing liquid carbon dioxide to the foam generating unit (110) until a preset pressure; a solution inlet (130) for supplying the surfactant solution at a predetermined concentration to the foam generating unit (110) and having a valve (V) capable of controlling a flow rate; an inline filter member (140) having a replaceable porous filter element in order to re-produce the carbon dioxide foam discharged from the foam generating unit (110) in a uniform foam size; a see-through pressure container (150) prepared on a transport pipe of the carbon dioxide foam, which performs circulation through the inline filter member (140) to the foam generating unit (110), and capable of watching the carbon dioxide foam flowing along the inner part thereof; and a circulation pump (160) for circulating fluid along the foam generating unit (110), the inline filter member (140), and the see-through pressure container (150).
