对世界所有大国而言，石油战略储备是十分重要的。为了满足国家安全的需要，世界不同国际组织如联合国、欧盟等都建议设立3个月的石油战略储备。对于中国而言，这就需要战略储备石油3×10⁷~9×10⁷ t，这需要一个长时间段和大量资金注入才能完成。如果基于“功能”储备补足“资源”储备的一个新理念来思考，这一目标可以较容易地完成。即储备一定百分数的甲醇来替代石油，则国家安全也可以得到保障。

The strategic oil reserve is very important for every large country in the world. In order to meet the basic requirement of the state safety, 3 months strategic oil reserve in every large country was proposed by the different international organizations such as UN, EU, etc. For China, the total amount of strategic oil reserve must be up to about 30 to 90 millions. It is very difficult to achieve it without enormous capita in short time. Based on a new conception as "function reserve" to replenish the "resource reserve", this goal could be more easy to be accomplished.Namely, storing more methanols replaces some percentage of oil. Moreover, the state safety should be ensured. This topic is discussed in the article in detail.
