- Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)
Abstract
Dans un procédé de production dhydrocarbures à partir dun réservoir souterrain comprenant des hydrocarbures visqueux et un acide organique, on injecte de la vapeur dans le réservoir pour chauffer et entraîner les hydrocarbures visqueux de façon à produire des hydrocarbures entraînés à partir du réservoir. Dans un mode de réalisation, on injecte aussi une vapeur de n-butylamine ou de n-propylamine dans le réservoir afin quelle réagisse avec lacide organique pour former un agent de surface. Lagent de surface réduit la tension superficielle entre les hydrocarbures et leau, accélérant ainsi le taux de production dhydrocarbures. Dans un autre mode de réalisation, on peut sélectionner pour linjection une amine volatile parmi des amines qui sont plus volatiles que la vapeur dans le réservoir et qui affichent des points d'ébullition denviron 45 à environ 80 degrés Celsius. Un mélange comprenant de la vapeur, ainsi quenviron 0,1 % à environ 0,2 % massique de lamine volatile, peut être injecté.
