辽河油田具有丰富的稠油资源，目前动用稠油地质储量占总动用储量的45%以上，而稠油年产量已占辽河油田年产油量的60%以上。因此，研究稠油油藏经济极限产量变化规律，对评估辽河油田特定油气资产和指导生产具有重要的现实意义。在研究经济极限产量的4个影响因素之后，重点讨论了油价对经济极限产量的影响。研究表明，在成本、商品率保持不变的情况下，辽河稠油经济极限产量随着油价的提高而降低，其递减规律为指数递减。

The heavy oil resource is abundant in Liaohe Oilfield. The developed recoverable heavy oil reserves are more than 42% of the
proved reserves. The yearly production of heavy oil is more than 60% of the total production in Liaohe Oilfield. The study on
fluctuating law of the heavy oil economic limit rate is very important. This law can be applied to evaluate the specific hydrocarbon
and guide producing. Four factors influencing on the economic limit rate have been analyzed. The oil price is the most important
factor. Study shows that the economic limit rate of heavy oil decreases with the increase of oil price under the condition of
unchangeable cost and commodity rate, which is exponential decline.
