摘　　要：油井初期产量是编制油田开发方案的重要参数,而油气储层的物性特征是油井初期产量的主控因素。根据已知油井初期产量、油气储层孔隙度和渗透率,通过最优拟合原则建立油井初期产量与油气储层孔隙度和渗透率最佳预测数学模型,基于预测数学模型对未知油井初期产量进行预测分析。结果表明,基于趋势面分析的油井初期产量预测方法是可行,其结果可靠,可以为油田编制开发方案提供参考依据。Oil well original output is one of important parameters for oilfield development planning. Reservoir characteristics are the main controlling factors of oil well original output. In the light of the known data about reservoir characteristics and oil well original output, the prediction model was constructed based on polynomial trend surface analysis. The model was used to predict the unknown oil wells original output. The results of an example illustrate that the method is simple and reliable in calculation, and is useful for predicting oil field output.
