稠油热采注汽管接箍对散热影响的研究

Study of the effect of tube's juncture on heat loss in viscous oil extraction

通过数值模拟的方法计算了稠油热采注汽管接箍对散热的影响,并提出了在工程应用中如何利用比较简单的结构来模拟结构比较复杂的接箍对散热的影响,即1/3等效法则。将该方法应用于实际稠油热采注汽管道的散热计算中,取得了较好的效果。

The effect of tube juncture on heat loss in viscous oil extraction is numerically investigated. On the basis of calculation, a method is presented that proposes how to use a simple configuration of tube juncture to replace the complex one in the process of heat loss calculation in viscous oil extraction, and is called as 1/3 equivalence method. The method has been applied to the practical steam inject tube's heat loss calculation in viscous oil extraction, and the result shows its feasibility in practical application.
