摘要
从渗流力学的基本原理出发,基于气水两相物质平衡方程和状态方程,结合运用两相拟压力的方法,建立了气水两相不稳定试井模型。考虑井筒储集效应和气体高速渗流的非达西效应的影响,得出无因次拟压力及其导数与无因次时间之间的关系,制作了气水两相流试井理论图版,为气水两相流试井解释研究提供了理论基础。
From the basic theory of fluid mechanics in porous medium,based on the material balance equation and state equation and combined with the method of pseudo-pressure,non-stabilized well test model is developed.Taking account of the effect of wellbore storage and the influence of non-Darcy effect,the relationship between dimensionless time and dimensionless pressure has been derived and theoretical plate of gas and water two-phase flow has been mapped out which provides a theoretical basement for well test interpretation of gas and water two-phase flow.
