The area of heated oil reservoir is inner surface area of emulsified crude oil (assumed). The reason is that the emulsifying of surfactant crude oil forms oil-in-water emulsion, its inner surface area is much greater than that outer surface. The increase of the area of the inner surface can be considered as Heaviside step function, its derivative is Dirac delta function. Internal energy of the system is divided into two parts, U b and U σ. U σ is surface energy, and U b is internal energy...

The area of heated oil reservoir is inner surface area of emulsified crude oil (assumed). The reason is that the emulsifying of surfactant crude oil forms oil-in-water emulsion, its inner surface area is much greater than that outer surface. The increase of the area of the inner surface can be considered as Heaviside step function, its derivative is Dirac delta function. Internal energy of the system is divided into two parts, U b and U σ. U σ is surface energy, and U b is internal energy of bulk phase (assumed).According above assumes the energy balance equation is derived, and heat transmission mechanisms in emulsion are discussed, the fact, that for the emulsion the spatial variation of temperature can be neglected, has been pointed out ,the temperature in oil drop is essentially uniform at any given time. The velocity of thermal diffusion in emulsion is much greater than that in oil reservoir. That is why steam injection with chemicals is better than steam injection. Field test makes sure of that steam injection with chemicals is a better method for producing the high viscous heavy oil.

假定 :油层的加热面积是乳化原油的内表面。这是由于在形成的水包油乳化液中 ,内表面远远大于外表面的面积。内表面的增加可以用Heaviside阶梯函数来描述 ,它的微分为Dirac函数。系统的内能可以分为两部分 ,一个是体相内能 ,一个是表面能。根据上述假定 ,我们导出了能量平衡方程 ,探讨了乳液的传热机理 ,指出在乳液中温度的空间变化可以忽略 ,油滴的温度可以认为是均一的和时间无关。在乳液中的热扩散速度比在油层中要快的多 ,这就是为什么蒸汽化学吞吐比蒸汽吞吐更好的原因之一。开采高粘度原油的现场试验也证实了这一点
