基于对油气田产量预测的 Weibull,Wengcycle模型的研究 ,提出一个综合模型——广义 Weibull Wengcycle模型。该模型不但可以预测油气田产量随时间的变化 ,而且也可预测油气田的可采储量、最高年产量及其发生时间。本文探讨了模型的性质、曲线特征 ,提出了一种新的求解参数的方法——等比级数法 ,并通过实例验证了此方法的可行性及该模型在油气田产量预测中的可靠性 Based on the study of Weibull and Wengcycle model for oil and gas field yield prediction, a generalized model-generalized Weibull Wengcycle model is proposed. The model not only predicts the evolution of oil and gas production over time, but also predicts the recoverable reserves, the highest annual yield and the time of its occurrence. This paper discusses the nature of the model and the characteristics of the curve and proposes a new method to solve the parameter - the geometric progression method. The feasibility of this method and the reliability of the model in oil and gas field production prediction
