摘要
本文从生产实际需要出发,建立了掺热水过程中杆内及油杆环空内流体与井简和地层岩石间的换热计算模型,并对核模型进行了数值求解。编制的微机程序具有使用方便,计算速度快,收敛性好等特点,可以用来计算任意时刻杆内及环空内流体的温度分布,为选择合理的井口热水掺入排量和温度提供理论依据。
In the oil production, it is an effective method to inject heated water in rod centre to prevent wax from precipitation. So it is necessary to calculate temperature field in thewell when heated water is injected to rod centre. But up to now, there is no way to dothat. In this paper, a model and method for calculating well temperature field in rokcentre injection has been presented. Practical calculation shows that the calculating val-ue is reasonable and the calculating method is practicable.
