摘要
油水两相压力数据解释是数值试井中最常见的问题。在解析试井中,拟合主要由鼠标拖动与自动拟合完成。由于数值试井可供调节的参数多、计算速度慢等原因,压力降落与压力导数拟合主要由人机交互完成。为此研究了饱和度分布、相渗曲线、粘度、体积系数等与试井曲线间的关系,并利用UST数值试井软件研究了参数改变时试井曲线的变化规律。掌握这些规律将有助于提高多相流数值试井拟合效率。
The pressure data interpretation of the oil-water two phase flow is the most common problem in the numerical well test.The analytical well test fitting is done by mouse movement and automatic fitting.Because of too many parameters to fit and slow speed of calculation,numerical well test fitting is mainly done by human computer interaction.Therefore the saturation distribution,relative permeability,viscosity,volume factor etc.are studied and UST numerical well test software is used to study the variation law of well test curves,which is helpful for user to improve the speed of interpretation.
