Abstract

Abstract: A technology for improving the temperature distribution of heat-sensitive oil in wellbore using heat pipe was proposed.Based on the heat transfer theory of two-phase closed thermosiphon and the model of thermal conduction with coupling heat pipe,a theoretical model for calculating the temperature distribution in wellbore with heat pipe was established.The mechanism and technological feasibility of improving fluid temperature distribution in wellbore using heat pipe were analyzed with this model.The applied results of this technology to Chu 32 Well in Huabei Oilfield showed that heat pipe can increase the temperature of fluid in the upper wellbore by absorbing the surplus thermal energy of the fluid in the lower wellbore.At the same time,it can improve the temperature distribution along the wellbore.This technology is significant to the economical production of heavy oil and heat-sensitive oil.

Key words: heat transfer theory, heat pipe, wellbore fluid, temperature distribution, calculation model

摘要： 为了寻求经济节能的改善热敏感性原油井筒流动特性的工艺技术,基于两相闭式热虹吸管工作原理,提出了利用热管改善井筒流体温度分布剖面的方法.结合井筒传热模型及耦合热管传热理论建立了热管井井筒温度分布计算理论模型,利用该模型分析论证了热管改善井筒流体温度分布的原理及技术可行性.现场试验及理论研究结果表明:在不消耗额外能量的前提下,利用热管可以实现利用深部流体自身部分能量提高井筒上部流体的温度,进而改善井筒温度分布剖面.
