石油可采储量是一个随着开采工艺技术和经济条件的变化而变化的动态值。用现金流通法计算石油经济可采储量共有七个步骤:①油藏地质评价;②油藏工程评价;③投资估算;④成本费用确定;⑤销售收入计算;⑥销售税金及附加的确定;⑦编制现金流量表。通过东部某油区注水开发的稀油油田和注水开发的高凝油油田经济可采储量的计算,进一步证实了现金流通法对于各类油田的经济可采储量计算的实用性。

Proved reserves of oil is a variable influence by the changing of available recovery technology and economic conditions. There are seven steps on calculating proved reserves of oil using cashflow method: ①Geologic evaluation of the reservoir. ②Reservoir engineering evaluation. ③Investment estimation. ④Determination of costs and expenditure. ⑤Sales revenue estimation. ⑥Sales taxes and fees estimation. ⑦Make the cashflow statement. Based on the calculation of the proved reserves of the water flooding light oil field and water flooding high pour point oilfield both on the eastern oil bearing area, we further proved the feasibility of the cashflow method on calculating the proved reserves of oil in different kinds of oilfields.
