摘　　要：产能递减规律和产量递减规律是气田制定工艺生产措施的重要依据,但具有不同的意义,目前国内对产量递减规律与产能递减规律的研究有相互混淆的状况。对产量递减规律与产能递减规律进行了对比分析,给出了产能的时间递减率、压力水平递减率和采出程度递减率的工程定义。实例分析表明,采用产能递减分析气藏(井)生产动态对气田生产具有更符合实际的指导意义。Production decline law and deliverability decline law are important basis for working out production measures of gasfield although with different significance. Currently,there is confusion between these two studies in China. In this paper,a correlation between the two laws is analyzed,and some definitions of time declining rate,pressure declining rate and recovery percent declining rate of deliverability are given. Case studies show that applying the deliverability decline to analyze production performance of gas reservoirs (wells) has guiding significance for gasfield production.
