井筒温度场在电加热井中的应用

对于电加热采油技术,明确井筒温度场分布是确定合理加热参数的关键。为了满足生产和节能的需要,探讨电加热井井筒温度分布的计算方法。从研究井筒温度分布出发,建立了温度分布的数学模型。通过计算绘制实际生产井井筒温度分布曲线,进而提出一种确定电加热井加热深度和加热功率的方法,为该采油技术的应用提供参考。

The application of wellbore temperature distribution in the electric heating wel

In the electrical heating production technique,the integrity of the knowledge in wellbore temperature distribution and conduction is always lacked so that no proper heating parameter is existed in the production and management and the requirement of the production and energy saving.As a result,the mathematical model of the wellbore temperature distuibution is established based on the research of wellbore temperature distribution.Curves of the wellbore temperature distribution of producing well is drawed by calculating.The measure that can fix heating depths and power of the electric heating wells is obtained,which supplies reference for the application of the electric heating technique.
