调和递减下年递减率与月递减率关系式的推导及应用

在油田的年度配产中,一年内每个月的递减率往往是变化的,产量高时递减率大,产量低时递减率小.本文运用递减理论,推导出了在调和递减规律下年递减率与月递减率的相互关系式,运用这种关系式能很好地将年产量分解到每个月中去,也能很好地将阶段递减率折算成年递减率,进一步丰富了产量递减理论,在实际工作中有一定的用途.

AN APPLICATION AND DERIVATION OF RELATIONSHIP BETWEEN THE YEALY PRODUCTION DECLINING RATE AND THE MONTHLY PRODUCTION DECLINING RATE WITH A HARMONIC DECLINE

The monthly production declining rate is often variedin a year in yearly production pro-ration of an oil field.The higher the production,the larger production declining rate with oc-cur other hand,the lower the production,the lower the production declining rate. Based onthe production declining theory ,relationship between the yearly production declining and themonihly production declinig rates is derived in this paper.With this expression,we can re-solve a year production into a month production by covering a monthly production decliningrate into a yearly production declining rate,which can be used in actual field practice.
