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 issues such as high investment costs risks and large uncertainties.Traditional evaluation methods include the Net Present Value, Differential Rents, Reserve Cost method, and Multiple Cost method.Energy Return on Investment (EROI) is a new economic evaluation method in recent years.These methods have their own advantages and disadvantages.This paper expounds the advantages, and shortcomings of different methods in practical application.However, the shortcomings should be avoided to establish a dynamic comprehensive economic evaluation system when implementing various economic evaluation methods.The purpose is to provide a scientific basis for the decision-making of right time selection as well as environmental and social impact for oil and gas resource development.
