摘要： 在油气田开发过程中,产量与可采储量预测是极其重要的一项工作。根据预测油气田产量的Weibull模型基本关系式,探讨了Weibull模型的性质,提出了求解模型参数的双重线性拟合法,并通过实例验证了该模型的实用性及有效性。此外,还得到两个重要认识,Weibull模型是广义的Wengcycle模型,是它的一般情况;Weibull模型不仅适用于油气田产量变化存在单峰的情形,也适用于油气田产量呈纯递减的情形。

Abstract: Prediction of production rate and reserves is a very important task during oil-gas field development. Weibull model for prediction of oil-gas field production rate is presented, including the basic correlations and its property. Dual linear simulation method for solving the model parameters is proposed. The practicability and validity of this model is verified by case study. Also, it is recognized that Weibull model is a generalized Wengcycle model in fact. This model not only adapts to the variation of oil-gas field production rate with single peak, but also to the declining case of oil-gas field production rate.

Key words: model, prediction, oil-gas field, production rate
