摘　　要：按照2004年颁布的新的《石油天然气资源/储量分类》(GB/T19492-2004)标准,为了建立和形成油气田技术可采储量、经济可采储量、次经济可采储量和剩余经济可采储量等新的可采储量系列,在总结国内外研究方法的基础上,结合油田的地质开发特点,根据我国现行的财税制度,以现金流法为主要方法,进一步研究提出了经济极限法、井网密度法、边际成本法、类比法等经济可采储量计算方法。根据各种方法的基本原理和应用条件,进行了归类分析。同时,建立了储量价值评估模型,对评估过程中参数的假设做了详细阐述,经济可采储量评估由实物量转向了实物量与价值量相结合,使得对经济可采储量、剩余经济可采储量的评估更加科学,并与国际储量评估方法接轨。According to the new criterion for Classification of Oil and Gas Resources/Reserves （GB/T19492-2004） issued in 2004, this paper reviews the studied methods at home and abroad for the purpose of establishment of new series of recoverable reserves such as technically recoverable reserves, economic recoverable reserves, sub-economic recoverable reserves and remaining economic recoverable reserves of oil-gas fields. Combined with the oilfield geology and development feature, this paper further researches and proposes the estimation methods for economic recoverable reserves such as economic limit, well pattern density, marginal cost and analogy ones, based on domestic current financial and taxation system and cash flow method followed by making category and analysis according to the basic principles and applied conditions of each method. Finally, this paper develops a model for estimation of the reserves value, which allows the estimations of the economic recoverable reserves and the remaining economic recoverable reserves to be more scientific by elahorating given parameters hypotheses and by converting the estimation of physical quantity into that of combination of both physical quantity and value quantity, thus brings the work in line with the international practice for reserves estimation.
