净现值和能源投资回报方法比较研究

Comparative Study of Discounted Cash Flow and Energy Returns on Investment

油气资源勘探开发面临投资成本高、风险高、不确定性等诸多问题,传统的油气资源经济评价方法有净现值法、级差地租(矿利)法、储量成本法以及未广泛使用的勘察费用倍数法等,近年来国际上涌现了新的经济评价方法——能源投资回报(Energy Return on Investment)方法,这些方法在油气资源经济评价过程中各有优劣。从能源经济评价的理论和方法角度,阐述了净现值法和能源投资回报方法在实际应用中的优点和不足。在国际油气项目开发经济评价案例中,应该综合各种经济评价方法的优点,规避缺陷,建立动态的经济评价体系,为油气资源开发的时间选择、最佳开发方式、环境社会影响等重要投资决策提供科学依据。

Oil and gas resources exploration are facing many problems such as high investment costs risks and large uncertainties.Traditional evaluation methods for oil&gas resources include the Net Present Value,Differential Rents,Reserve Cost method,and Multiple Cost method.Energy Return on Investment is a new economic evaluation method.These methods have their own advantages and disadvantages.This article expounds the advantages,and shortcomings of different methods in practical application.However,the shortcomings should be avoided to establish a dynamic economic evaluation system when implementing various economic evaluation methods.The purpose is to provide the right time selection as well as environmental and social impact under a scientific basis for oil and gas resource development.
