低粘度油包酸酸化乳液及使用方法文中描述了低粘度油包酸乳液，表面活性剂体系及使用乳液和表面活性剂的方法。该乳液用于强化采油。低粘度油包酸由（１）形成外相的油；（２）形成并能稳定油包酸乳液的乳化剂；（３）降粘剂；（４）形成乳液内相的水基酸组成。油包酸乳液... Low Viscosity Oil Coated Acidification Emulsion and Method of Use Thereof Described are low viscosity oil-in-oil emulsions, surfactant systems, and methods of using emulsions and surfactants. This emulsion is used for enhanced oil recovery. Low viscosity coalesced oil consists of (1) an oil that forms the outer phase; (2) an emulsifier that forms and stabilizes the oil-in-sour emulsion; (3) a viscosity reducer; and (4) a water-based acid that forms the internal phase of the emulsion. Oil-coated acid emulsion ...
