1.
The graph of growth curve in its growth process is normally characterized by an oblate shape like "S".
增长曲线的增长过程中,其图形表现为像一条压扁的S形曲线,在油田勘探、开发、生产过程中,很多实际生产数据也呈现出S形的增长趋势。
2.
Six growth curves used for prediction of oilfield development indexes expressed with trigonometric function are proposed,thus perfecting and abounding in the existed growth curve methods further.
提出了用三角函数表示的一类用于油田开发指标预测的增长曲线共6条,从而进一步完善和丰富了现有的增长曲线法。
3.
A new growth curve to predict indices of oilfield development, N p=N Rmax t/(a+t)] b, has been proposed, and its formulae for calculating production (Q t) vs time (t), maximum production (Q tmax ), time according maximum production (t m) and Reserves Production Reserves(RPR) have been derived.
提出了一种预测油田开发指标的新型增长曲线 :Np =NRmax[t/(a +t) ]b。
