摘　　要：Compertz模型参数估计问题是一个三维数值优化问题,常规算法在求解方面存在一定的困难。为此,提出了一种数学处理方法,将三维优化问题归结为一元非线性方程进行求解,并给出了该一元方程的解区间搜索算法和二分法求解算法,可应用于石油地质储量、油田产量预测等问题。实际算例表明,该算法计算过程稳定,计算速度快,计算误差小。Estimation of Compertz model parameters deals with 3D numerical optimization.The conventional algorithm has some difficulties in computation;hence a mathematical method is proposed to resolve 3D optimization into a nonlinear equation with one unknown. This paper also presents a search algorithm of feasible region and a bisection algorithm for this equation.This method can be used to predict original oil in place and oilfield production.Case calculation shows that this algorithm is stable and fast in calculation process and has small calculation error.
