摘要： 从产量递减率定义出发,首先导出了综合递减率与开井数、含水、产液厚度、压力、相对产液指数、井网密度、表皮系数等多因素分析模型。在此基础上,结合一般油田的生产测试数据特点和自然递减率与综合递减率的关系,建立了自然递减率多因素分析模型。该模型可准确地分析各相关因素对递减率的影响程度,从而为制定控制油田自然递减率的调整对策提供了依据。经油田实际应用,效果很好,值得推广应用。

Abstract: Based on the definition of production decline rate, the multifactor analytical model for composite decline rate is developed, which discusses affecting factors such as the startup well number, water cut, producing fluid thickness, pressure, relative production index, well spacing density, skin factor, etc.Integrated with the correlation between natural and composite decline rates as well as the characteristic of production testing data, the model for natural decline rate is established.The model can be used to analyze accurately the effect of individual interrelated factor on production decline rate, support regulative countermeasures and modify the natural decline rate in an oilfield.The case study indicates that this model is effective in practice and good for popularization.
