摘　　要：储采比是油气田产量保证程度的一种指标,该值越大,产量稳定实现的可能性越高。当储采比低于某一数值时,油田开发即进入递减阶段。为此,在Arps和Logistic产量递减方程理论研究的基础上,分别导出了油田产量遵循不同递减规律时储采比与时间的关系式。在这些关系式中,当t取0时,可直接确定出油田保持稳产时所需的储采比下限值。通过这些研究,为油气田稳产形势的分析、评价以及规划提供了可靠的理论基础。经实例验证,效果很好。The reserve-production ratio is an index of ensuring production from an oil-gas field.The higher it is,the bigger possibility of realizing stabilized production is.If the ratio is less than certain numerical value,the related oilfield development will turn into declining stage.This paper,based on theoretical study of Arps and Logistic production declining equations,derives the expressions of the ratio vs time for production following different declining laws,respectively.Among them,the cutoff values of reserve-production ratio for stable production as necessary can be directly defined at t=0.The studied results provide reliable theoretical basis for analysis,evaluation and planning of an oil-gas field's stabilized production status.The actual cases have shown very good effects.
