When steam is poured from top of oil well, Heat loss from tubing to earth layer should decrease as well as possibly in order to make dry degree of steam at the end of well high.

在从油管中的注入蒸汽过程中,必须最大限度地减少由井筒向地层的热损失,保证注入井底的蒸汽干度较高。

Steam thermal recovery is the dominant technology of the heavy oil recovery. There have been varying degrees heat loss in steaming system production run, gas production ,transportation, steaming huff and puff etc.

蒸汽热力采油是稠油开采的主导工艺技术,注汽系统在生产运行中,在产汽、输送、注汽吞吐等各环节中,都存在着不同程度的热能损失。

A heat loss parameter K, i. e. the ratio of thequantity of heat loss to the quantity of heat generation, was introduced to the model.

建模的过程中引进了热损失参数K，即燃烧过程中热损失量与热生成量的比值。
