摘要：

Remaining recoverable reserves, remaining recoverable reserves-production ratio and remaining recoverable degree are key indices for judging the current development status of oil and gas fields and provide an important basis for determining whether to adjust the development scheme, thus attracting high attention from global oil companies. According to national industry standards, the main evaluation methods of recoverable reserves include waterflooding curve method, production decline method and forecast model method. The waterflooding curve method is only applied to waterflooding oilfields, while production decline method and forecast model method can be used for any oilfields of all reserving types, flooding types and production modes in the decline stage. DeGolyer and MacNaughton Company and Ryder Scott Company were hired to evaluate the annual reserves asset values of remaining economical recoverable reserves for all national oil and gas fields. The evaluation method they adopt is the variation formula of Arps exponential decline method proposed by the U.S. Securities and Exchange Commission multi-department team. In this study, the generalized exponential decline method applicable to different development modes is used to derive the calculation equations of annual economical recoverable reserves, remaining economical recoverable reserves, technical recoverable reserves, remaining technical recoverable reserves, remaining recoverable reserves-production ratio and remaining recoverable degree of oil and gas fields. In the meantime, the variant exponential decline method adopted by DeGolyer and MacNaughton Company was illustrated and evaluated. The calculation methods presented by the author were confirmed practical and effective in terms of actual application results in eight oilfields. © 2016, Editorial Office of ACTA PETROLEI SINICA.
