摘要
中国现行规范中 ,将地质储量分为 3级 :探明、控制和预测储量。表面上看 ,与国际上几个具代表性分类之间相比 ,大体可一一对号入座 ,但具体操作上差别十分明显 ,最根本的是没有或很少考虑经济因素。为与国际接轨 ,将经济可采储量列入储量报告势在必行。在进行经济可采储量评估时 ,除运用递减法进行产量预测外 ,还应充分考虑操作成本和费用、与产量相关的税费、开发投资、油产品价格和折现率等评价参数的影响。运用该方法对济阳坳陷东辛油田的剩余可采储量进行了分析和预测。结果表明 ,剩余经济可采储量的大小除受产量递减规律影响外 ,油价的影响最为显著 ,特别是当油价低于 2 0美元 /桶时 。
According to the current standard used in China,the geological reserves can be divided into three categories: proved reserves,controlled reserves and prognostic reserves Seemingly, these reserves can be approximately correlated with the proved,probable and possible reserves commonly used in the world However there are remarkable differences in actual operation The essential difference is that economic factors has scarcely or seldom been considered For the sake of being coincide with those practiced in the world, it may be imperative to list commercial recoverable reserves in our reserves report Except applying the successive subtraction method to production prediction while evaluating the commercial recoverable reserves,various parameters should also be considered,such as operational cost and expenditure, expenses of taxation associated with production, development investment, prices of oil products, discount rate,and etc This method has been used to analyze and predict the commercial recoverable reserves in Dongxin oilfield The result shows that the magnitude of remaining commercial recoverable reserves has been affected by the regular pattern of production decline,but it has most obviously been affected by oil prices, especially when the oil price is lower thanS|20 (US)/bbl
