以油气预测储量区块为研究对象，以优选区块升级为目的，提出了升级性评价方法、升级率评价方法、经济评价方法及综合评价方法。研究提出：升级难易程度指数值用于升级性定量评价；升级概率值用于升级率评价；贴现现金流法计算的储量价值用于经济评价。综合评价则利用升级难易程度指数值、升级概率值、经济价值“一维排队，三维优选”。利用综合评价值，将预测储量区块分为可升级并获得大中规模储量区块、可升级并获得中小规模储量区块、需要评价研究升级的储量区块、暂不升级的储量区块4类，便于勘探决策。
以油氣預測儲量區塊為研究對象，以優選區塊升級為目的，提齣瞭升級性評價方法、升級率評價方法、經濟評價方法及綜閤評價方法。研究提齣：升級難易程度指數值用于升級性定量評價；升級概率值用于升級率評價；貼現現金流法計算的儲量價值用于經濟評價。綜閤評價則利用升級難易程度指數值、升級概率值、經濟價值“一維排隊，三維優選”。利用綜閤評價值，將預測儲量區塊分為可升級併穫得大中規模儲量區塊、可升級併穫得中小規模儲量區塊、需要評價研究升級的儲量區塊、暫不升級的儲量區塊4類，便于勘探決策。

Predicted hydrocarbon reserves were studied, and four evaluation methods for improving reserve esti?mates were proposed, including possibility evaluation, upgrading rate evaluation, economic evaluation and com?prehensive evaluation. A difficulty index was used to evaluate the possibility of reserve upgrading. Reserve upgra?ding probability calculation and test were used to evaluate the upgrading rate. A discounted cash flow method was applied in the economic evaluation. The difficulty index, probability calculation and economic methods were jointly used in the comprehensive evaluation. The predicted hydrocarbon reserve blocks were classified into four types according to the comprehensive evaluation, including the blocks with large or medium potential for upgra?ding, the blocks with medium or small potential for upgrading, the blocks remaining for evaluation, and the blocks not to upgrade at present.
