Meanwhile,the author divides the oilfield production decline rate into the liquid production rate natural decline and t.
同时将油田产量自然递减率分解成产液量自然递减率和含水上升因子2个主要部分,分析了产液量和含水对产量自然递减率影响所占的比例,并预测了开发指标。

A differential equation for production decline rate is set up based on the study of variation of production decline curve,by which the dimensionless decline equation for describing the production decline rule is deduced.
根据产量递减曲线变化特征,建立了产量递减率微分方程,并由此得到了描述产量递减规律的无因次递减方程。
