摘要
在分析实际低速非达西双重孔隙介质油藏中途测试 (DST)非自喷井渗流规律的基础上 ,导出了其有效井径数学模型 ,利用拉氏变换及特殊物理方程理论 ,导出了该模型的拉氏空间解析解 ,并利用简便的Stehfest数值算法进行数值反演 ,得出了实空间解 ,绘制了无因次样板曲线。
On the basis of analysis on the rules of percolation of non-flow well in drill stem test (DST) of reservoirs with actual low velocity and non-Darcy double porous medium, a mathematical model of its effective well diameter is derived, Laplace inversion and the theory of special physical equations are used to derive the Laplace special analytical equations, and the simplified Stehfest algorithm is used to conduct a numerical inversion for obtaining a actual special solution, and dimensionless type-curves are drawn, which can be used effectively for field analysis of DST slug flow well testing.
