摘要

为了解决油管电加热井能耗高的问题,实现稠油井的节能生产,依据非稳态传热学模型,综合考虑抽油机举升能耗与电加热装置能耗,建立了油管电加热降黏举升工艺数学模型。综合考虑抽油机耗电和电加热耗电,分析了电加热功率对井筒温度场、井筒内黏滞阻力及电机有功耗电的影响,在此基础上,优化给出了合理的电加热功率。分析结果表明:所建模型能较好地模拟出电加热井筒温度场;合理的电加热功率应使井筒内的原油温度要高于凝固点温度,使原油具有较好的流动性,确保将高黏度稠油举升到地面。研究的优化方法可为电加热井节能生产提供技术指导。
        To address the high energy consumption of electric heating tubing wells and achieve energy-saving production,based on the unsteady heat transfer model,comprehensively considering the energy consumption of pumping unit and electric heating device,the mathematical model of electric heating tubing viscosity-reducing lifting is established. Comprehensively considering the power consumption of pumping unit and electric heating tubing,optimized electric heating power is obtained. The analysis results show that the model can simulate the temperature field of electric heating well. Proper electric heating power should make the crude oil temperature in the wellbore higher than the freezing point temperature,providing better crude oil fluidity to lift the high viscosity heavy oil to the ground. The optimization method can provide technical guidance for energy-saving heavy oil production of electric heating wells.
