地层热阻是稠油和高凝油进行热力开采时的重要基础数据,它关系到采出原油在井筒中的温度分布。目前,尚无有效的方法能得到油田上实际的地层热阻。本文根据热力学、传热学的原理,分析了影响地层热阻的各种因素,提出了利用实测的连续井温分布反算地层热阻的方法。运用这种方法对辽河油田三口油井的地层热阻进行了实际测算。结果表明,在同一地区,对多口油井进行测算,就可得到该地区的实际地层热阻值。 The thermal resistance of the formation is an important basic data for the thermal exploitation of heavy oil and high oil content, which is related to the temperature distribution of the produced crude oil in the wellbore. At present, there is no effective way to get the actual formation thermal resistance on the field. Based on the principles of thermodynamics and heat transfer, the paper analyzes various factors that affect the thermal resistance of the formation and proposes a method of calculating the thermal resistance of the formation using the measured continuous well temperature distribution. This method is used to measure the thermal resistance of three wells in Liaohe Oilfield. The results show that, in the same area, the number of wells measured, you can get the actual formation thermal resistance value.
