摘　　要：以BZ25-1油田为例分析平均渗透率、有效厚度、生产压差水平等因素对油田单井产量的影响。引入灰色关联分析方法,得到BZ25-1油田各个影响因素与单井产油量的灰关联度。获取平均渗透率、有效厚度、比采油指数、生产压差、平均含油饱和度这五个影响参数的最优组合,优化生产压差和比采油指数,可实现油田相对稳定高产的目的。Taking BZ25-1 oil field as an example,this paper makes an analysis of the average permeability,the effective thickness,the level of SPI,the average oil saturation and other factors of single well production in field.Through the introduction of gray correlation analysis method,we could obtain the gray relational grade of various influencing factors and single well oil production in BZ25-1 field.This paper obtains that there outer to be a set of optimal values of the five factors,the average permeability,the effective thickness,SPI,drawdown pressure and the average oil saturation,optimization of drawdown pressure and SPI that would meet a high-yield remained relatively stable and the minimum energy consumption for an oil field.
