根据传热学和能量平衡原理 ,考虑环空产出液与油管掺入液及地层之间的双重热传导作用 ,同时考虑了由流体相变导致的焦耳汤姆森效应 ,建立了稠油泵井筒流体温度分布数学模型 ,并研究了温度分布随时间的变化规律。编制了计算程序 ,该程序能用于计算任意生产时间及井筒深度下掺入液及产出液的温度。计算结果表明 ,在一定条件下 ,生产时间及焦耳汤姆森效应对井筒温度分布有明显的影响。
According to the principle of heat transfer and energy balance, considering the dual heat conduction between the annular fluid and the oil pipe and considering the Joule-Thomson effect caused by fluid phase transition, the fluid temperature Distribution of mathematical models, and study the temperature distribution with time variation. A calculation program has been developed that can be used to calculate the temperature of sparge and effluent at any production time and well depth. The calculation results show that under certain conditions, production time and Joule Thomson effect have a significant effect on wellbore temperature distribution.
