在油田的开发过程中，油田储采比、储采平衡率是两个极其重要的开发管理指标。
During the development of oilfield, reserve -production ratio 'and balance rate are two extremely important development management indexes.
当储采比接近于10时，油气田开发可能会进入递减阶段。
When the reserve-production ratio approaches to10 years, the development of a field may come to a declining stage.
基于威布尔预测模型的扩展推导，提出了预测油气田剩馀可采储量和储采比的方法。
Based on the results from an extended derivation of Weibull Model, the methods to predict remaining reserves and reserve-production ratio of oil and gas fields are proposed in this paper.
储采比低于9以后，油田产量将以很快的速度递减。
If the ratio is lower than9, much more rapid production decline will appear for such an oilfield.
但由于勘探难度增大，使储量增长速度明显放慢，储采比快速下降，若无新的发现，将无法保证长期高产稳产。
Because the exploration difficulty increased, the reserve accreting velocity was obviously slowed down and there was a rapid drop in the reserve production ratio.
因此，研究储采比并建立储采比与递减率之间关系具有重要的意义。
Therefore, it is of great significance to study the reserve production ratio and establish the relationship between the reserve production ratio and the decline rate.
