A Quasi-Generalized Growth Curve to Predict Indexes of Oilfield Development.

b t t c factor growth curve,a new kind of quasi-generalized growth curve,which can be used to predict in-dexes of oilfield development,was proposed.The studies show that the ratio of cumulative production and maximum re-coverable reserves corresponding to maximum production is ranged from0to1.0for this growth curve.The end section of the relationship of Q t vs.N p can be concave upward or downward,and the relationship of both Q t vs.t and N p vs.t has the analytical expression respectively.The repeated duality regression method obtaining the parameters of this growth curve was presented.An example from Qingzuji oilfield shows that this growth curve has a greater value for application.
