摘　　要：稠油掺稀可以大幅度地降低原油粘度,减少摩擦阻力,提高原油的流动系数,是稠油井开采的一种常规方式。基于稠油粘度对温度的敏感性,分别根据正掺和反掺两种掺稀方式建立了井筒温度分布的模型,对掺稀油井温度场进行了计算和分析研究。由计算结果可知:影响稠油井井筒温度分布的主要因素为油井含水率、掺入点深度、掺入稀油量和掺入稀油井口温度;用VB语言编制程序计算得出不同条件下的井筒温度分布曲线,通过对比分析确定掺稀降粘的关键敏感因素。Mixing light oil in heavy oil wells can greatly decrease crude oil viscosity and friction to increase flow coefficient of crude oil, which is a conventional way of heavy oil exploitation. Based on the sensibility of heavy oil to temperature, the mode of wellbore temperature distribution was established according to normal-doped and anti-doped means, and the temperature field of heavy oil wells with injection of light oil was calculated and analyzed. The result shows that： main factors of heavy oil wellbore temperature distribution attribute to moisture content, incorporation depth, quantity and wellhead temperature of light oil;Wellbore temperature distribution curves under different conditions were calculated through VB language software, which could determine the crucial sensitive factors of mixing light and reducing viscosity via comparative analysis.
