摘　　要：研究大庆长垣各油田的产量递减规律证实,油田稳产期结束后,产量将以n=0.5的双曲线规律递减。在此基础上推导出了计算油田储采比的理论公式,并对油田合理储采比进行了论证。油田合理储采比应保持在9以上。储采比低于9以后,油田产量将以很快的速度递减。Based on the production decline patterns from Daqing placanticline oilfields,it is indicated that by the end of stable production period of an oilfield,its production decline will take place in terms of hyperbolic style with n=0.5.This paper derived theoretical equations for calculating reserve-production ratio and verified the rational ratio suitable for an oilfield.The proposed rational ratio should be remained to be e-qual to and greater than9.If the ratio is lower than9,much more rapid production decline will appear for such an oilfield.
