摘要: 给出了几种主要的产量递减率计算方法并研究了影响因素,分析了油田稳产期末产量递减率与稳产期的采油速度、稳产期长短和稳产期末可采储量采出程度的关系;研究了水驱油田自然递减率与含水率阶段、含水上升率和采液速度水平的关系;提出了结构递减率的概念,研究了不同结构对油田总递减率的影响,最后针对大庆油田水驱和聚合物驱共存的特点,定量分析了不同因素对递减率的影响幅度。对油田开发规划编制人员具有重要的参考作用。

关键词: 自然递减率, 采油速度, 采出程度, 结构递减率, 含水率

Abstract: The several methods mainly used to calculate the production decline rate are presented. The relationships between production decline rate and oil production rate during stabilization period, duration of stabilization period and recovery percent of recoverable reserves at the end of stabilization period are analyzed. The relationships between natural decline rate and water cut stage, raising rate of water cut and fluid production rate are further studied in water flooding oilfield. It proposes the concept of structural decline rate and studies the effect of different structures on the whole decline rate in oilfield. Finally, according to the coexistence characteristics of water flooding and polymer flooding in Daqing Oilfield, it quantitatively analyzes affection extent of different factors to decline rate, playing an important reference role for technicians who engage in oilfield development planning.

Key words: natural decline rate, oil production rate, recovery percent, structural decline rate, water cut
