采油井合理井底压力界限的确定方法

A METHOD FOR DETERMINING OF REASONABLE BOTTOM HOLE PRESSURE OFPRODUCTION WELLS

在理论研究的基础上， 根据不同油田的实际资料， 给出了一个确定油井合理井底压力界限的经验公式。有了这个公式， 只要知道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。提供的方法简便适用， 很容易为油田工程人员所掌握。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。

This paper gives an empirical formula for determing reasonable bottom hole pressure of production wells based on theoretical study and practical data of various oil fields. With the known formation pressure and saturation pressure, this formula helps to calculate the lowest allowable flowing pressure of a well or an oil field. This method is applicable for oil field engineers. The obtained lowest allowable flowing pressure value can be used as an important basis for allocation and design of an oil field.
