摘　　要：目前计算递减率的方法很多,虽然都能从不同方面反映产量的递减情况,但意义有所不同,不能当作相同指标来引用和对比。本文重新研究了三种递减率的计算方法,研究表明:第三种计算方法与实际情况结合较为精密,能真实的反应出油田的递减情况;研究认为:利用选定的计算方法可以准确的预测递减率,并安排年度分月产量生产计划,进而指导油田经济高效的开发。Calculting the decline rate has many methods now,although they can reflect the production decline situa-tion from different aspects,but the meaning is different,not as the same indicators to reference and contrast. The cal-culation methods of this paper are to study the three kinds of decline rate,research has shown that the third method combined with actual situation more precision,can true reflect a decline situation of the oilfield;Using the selected calculation method can accurately predict decline rate first,second preliminary annual production on the monthly production plan arrangement,thus guide oilfield economic and efficient development.
