挥发性油井井底油气两相区半径的计算方法

Calculations of Radiuses of oil and Gas Two-Phase Flow Area of Bottom Hole Reservoir in A Volatile Oil Well.

针对目前在挥发油藏开发中，生产井井底油层出现油气分离时，油气两相区域范围给予定量、快速评价的方法还很少的问题。根据油气两相区和单相区流体的不同特点，提出了挥发性油井井底油层油气两相区半径的计算方法，为准确评价挥发性油藏的开采提供必要的参数。

Volatile oil reservoirs are almost found everywhere, but few methods are available to quantitatively and quickly evaluate their regional extents resulted from oil/gas segregation in bottom hole volatile oil zone for a production well. This article presents a procedure for calculating these regional radiuses based on fluid properties of oil/gas two-phase flow and single phase flow regions, which provides necessary parameters for proper evaluation of volatile oil reservoir production.
