用分布参数电路模型研究稠油油井加热功率问题

Study on the heating power of heavy oil well using distributing parameter circuit model

用分布参数电路模型对稠油油井中频加热功率沿井深的分布进行了深入研究.得出油井井筒加热过程中热功率随井深按非线性规律变化,越靠近井口发热功率越大.这正好弥补了稠油提升过程中温度的下降,从而提高了加热效率、降低加热成本,达到节能降耗的目的.

The power distribution of heavy oil well along well-bore in medium-frequency heating is investigated by means of distributing parameter circuit model. And a conclusion is drawn that the heating power distribution is nonlinear and the nearer from wellhead, the greater the power, which makes up just the reduction of temperature in the process of heavy oil being raised. Therefore, the heating efficiency is improved, and heating cost is reduced.
