井底压力的计算方法

A Calculation Method to the Reasonable Bottom Hole Pressure

在理论研究的基础上 ,根据不同油田的实际资料 ,给出了确定油井合理井底压力界限的经验公式。若已知地层压力和饱和压力 ,便可计算出油井或油田的最低允许流动压力。该方法简便实用 ,且得到的最低允许流动压力数值可作为油田配产和油田规划设计的重要依据。

In this paper, based on the theory study, and according to the practical data in different oil field, the experiment formula aimed at determined the reasonable limit bottom pressure is represented. If the formation pressure and saturation pressure are known, the lowest permit flow pressure can be calculated and offer an important foundation to the allocation and design in oil field.
