    摘要： A solids-stabilized oil-in-water emulsion and a method for preparing the solids-stabilized oil-in-water emulsion. The oil-in-water emulsion is formed by combining oil, water, solid particles and a pH enhancing agent and mixing until the solid-stabilized oil-in-water emulsion is formed. The low viscosity oil-in-water emulsion can be used to enhance production of oil from subterranean reservoirs. The low viscosity oil-in-water emulsion can also be used to enhance the transportation of oil through a pipeline.

    摘要翻译： 固体稳定的水包油乳液和制备固体稳定的水包油乳液的方法。 水包油乳液通过将油，水，固体颗粒和pH增强剂混合并混合直至形成固体稳定的水包油乳液形成。 低粘度的水包油乳液可用于增强从地下储层的油的生产。 低粘度水包油乳液也可用于增强油通过管道输送。

    摘要： Method to determine the viscosity of a water-in-oil emulsion that will be formed by an oil comprising organic acids when mixed with water comprising: determining the value of the expression: η ( emul ) = K ⁢   ⁢ η ( oil ) ⁢ TAN - r ( 1 - ϕ ) 2.5 wherein η(oil) is the viscosity the oil, TAN is the total acid number of the oil, φ is a number in the range of 0.1 to 0.8, r is a number in the range of about 0.5 to 2, and K is a number from about 1 to 20, said determined value, η(emul) being the viscosity of the water-in-oil emulsion. The method is used to prepare water-in-oil emulsions of predetermined viscosity and to improve desalting of oils.
