蒸汽和热水注入项目的设计需要估计套管温度和井筒热损失。几位作者已经证明，如果总的换热系数已知，则可以计算井筒热损失和套管温度。给出了一个简单的推导，说明了各种换热机制是如何包含在总的换热系数中的。给出了确定总换热系数的简化计算方法。预测的套管温度与现场套管温度的比较证实了所建议的工程计算方法的基本公式和适用性。(参考文献10)
The design of steam and hot water injection projects requires estimation of casing temperatures and wellbore heat losses. Several authors have shown that well bore heat losses and casing temperatures can be calculated if the overall heat transfer coefficient is known. A brief derivation is presented to indicate how various heat transfer mechanisms are included in an overall heat transfer coefficient. A simplified calculation procedure is outlined for determining the overall heat transfer coefficient. Comparison of predicted and field casing temperatures confirms the basic formulation and applicability of the suggested procedure for engineering calculations. (10 refs.)
