油水两相流试井新型解释图版研制及应用

Development of a New Type of Interpretation Type Curves for Two Phase Flow Well Testing of Oil and Water and Its Application

应用注水油藏的多组合模型，从理论上研究了注水油藏的不稳定压力特征，通过合理的参数组合，提出了一种更具实用价值的新型注水油藏压降试井理论图版。利用这一理论图版与实测曲线拟合，可进行地层参数的定量解释，并获得相对渗透率分布曲线。

This paper, by use of multiple combination model for water injection reservoir, theoretically studies transient pressure characteristics of water injection reservoir, and through reasonable combination of parameters, presents a more practical new type of theoretical type curves for pressure draw down test in water injection reservoir. Using this theoretical type curves to match with measured curve may quantitatively evaluate formation parameters and generate a distribution curve of relative permeability.
