能源投入回报法是一种新兴的能源资源开发评价方法,区别于以货币为衡量标准的折现现金流法,其关注能源资源开发过程中的能量流。本文从理论和数理公式两方面探索能源投入回报法与折现现金流法之间的关联,并对两者的衡量标准进行了分析,最后以大庆油田为例进行了实例研究。研究发现,仅通过折现现金流法对能源资源开发项目可行性进行的评价并不充分,从社会可持续发展的角度,社会需要源源不断的能源供应,而折现现金流法难以保证能源资源开发能够产出净能源;但是侧重能源的投入与产出的能源投入回报法并没有形成具有普遍性的公认判断标准,所以针对同一种能源资源,能源投入回报值应该作为一种辅助指标,结合折现现金流的衡量标准,共同对能源资源开发项目的可行性进行判断。
The energy return method is a new method for evaluating the development of energy resources, which is different from the discounted cash flow method based on the monetary standard. It focuses on the energy flow in the process of energy resource development. This article explores the relationship between the energy return method and the discounted cash flow method from two aspects of theory and mathematical formula, and analyzes the two measurement standards. Finally, an example is given to Daqing Oilfield. The study finds that the evaluation of the feasibility of energy resource development project is not sufficient only through discounted cash flow method. From the perspective of social sustainable development, society needs a steady stream of energy supply, and the discounted cash flow method can not guarantee the energy resource Development can produce net energy; however, energy input-return method, which focuses on input and output of energy, does not form a universally accepted standard for judgment. Therefore, the return on energy input for the same energy resource should be used as a supplementary indicator The measure of discounted cash flows together determines the viability of an energy resource development project.
