摘　　要：在对沈采实际区块进行油藏工程评价过程中,在对原有的综合递减率算法进行分析总结基础上对其进行了优化,提出了更具有宏观性的新算法.新算法克服了原油算法所受影响因素较多的特点,只与评价的递减区间端点的年产油量和区间长度有关.新算法降低了年产油量的波动对参数结果的影响,进而增强了对油田整体生产情况的把握分析能力,更准确地反应了油田的现状,进一步为油田区块今后的开发方案的调整与部署提供参考依据.新算法的优越性最后通过现场实例得到了验证.This paper optimized the composite decline rate algorithm on the basis of the original algorithm and a more macroscopic algorithm is proposed in the process of reser- voir engineering evaluation to actual block of Shen Cal. The new algorithm overcomes the characteristics that the original algorithm is affected by many factors~ it only have a relation- ship with the oil production for one calendar year of the endpoint and length of decreasing interval. It can provide a reference basis on adjustment and deployment for oil fileld devel- opment program in the future.The superiority of the new algorithm finally verified through the instance.
