电加热井的井筒温度场数学模型

运用传热学理论，通过对稠油从井底流出井筒的温度变化、井筒原油与地层之间热交换过程的传热机理研究，建立数学模型，可以模拟不同产量、不同含水的井筒温度剖面，以及电加热所需功率，从而为稠油井电加热生产方案的制定提供科学依据。

The Mathematic Model of Elect-Heating Well in the Well Bore Temperature Field

Used the theory of heat transfer theory and based on the study of heat transfer mechanism both the transfer processes between the oil in well bore and formation and the temperature change in well bore when the viscous crude outflow form the well bore, the paper has established the mathematic model. It may simulate the different cross-sectional temperature in the well bore of the different production and different water cut, and the power needed by electric heating. Thereby, it can offer scientific bases in terms of production project of electric heating for viscous crude well.
