As the hard core of this paper, this chapter gives a frame which will help us to understand the new economic evaluation method of oil - gas projects better at first, then discusses the binomial model and the parameters estimating methods of abandon real options in the exploring phase, the partial differential equation model and the parameters estimating methods of the shut - down real options in the developing phase respectively. in the course of ascertaining the parameters estimating methods, this chapter discusses the application of a mathematic method - the monte carlo simulation in this article particularly
做為全文的核心，先提出勘探項目經濟評價新方法研究的總體框架，然後具體討論確定勘探階段放棄期權的二叉樹實物期權模型與參數確定方法、開發階段停啟期權的偏微分實物期權模型與參數確定方法，在參數確定過程中，詳細闡述了蒙特卡羅模擬這一數學工具在本論文方法中的應用；第五，案例分析及方法應用探討。 -
A new economic evaluation method of oil - gas exploration and development is established in the article. the hard core of the article is that : discussing the applying theory of the oil - gas exploration and development economic evaluation based on the real options, analyzing and confirming the binomial model of the abandon option in the exploring phase and the partial differential equation of the shut - down option in the developing phase fitting for most oil - gas projects, ascertaining correlative factors based on real projects and the methods how to estimate parameters
本文要構建一種基於實物期權法的油氣勘探開發類項目的經濟評價方法，探討基於實物期權法的油氣勘探開發經濟評價方法的應用原理，提出適合大多油氣勘探開發項目的勘探階段放棄期權二叉樹模型和開發階段停啟期權偏微分方程，確定基於該類項目實際的相關參數，並提供解決參數估計的方法。
