Research on viscosity-reduction technology by electric heating and blending light oil in ultra-deep heavy oil wells

In the Tahe oilfield in China, heavy oil is commonly lifted using the light oil blending technology. However, due to the lack of light oil, the production of heavy oil has been seriously limited. Thus, a new compound technology of light oil blending and electric heating is discussed in this paper, w...

Description
Summary:In the Tahe oilfield in China, heavy oil is commonly lifted using the light oil blending technology. However, due to the lack of light oil, the production of heavy oil has been seriously limited. Thus, a new compound technology of light oil blending and electric heating is discussed in this paper, which aims to reduce the usage of light oil and maintain heavy oil production. Based on the mass, momentum and energy conservation, a pressure and temperature coupling model is developed. The heat-transfer parameters are calculated by using Hasan–Kabir method and the pressure drop is calculated by using Hagedorn–Brown method. The model also considers the blend effect of light oil and heavy oil, and the heating effect of electric rod. Example calculation shows that only electric heating or light oil blending technology cannot meet the requirement. The amount of light oil used can be reduced by combining the electric heating technology.
