摘　　要：从多相渗流分类和溶解气驱油藏油气两相渗流两个方面,对试井分析研究现状进行了总结和评述,提出中国油气田大量存在着油气、油水、气水两相、油气水三相的多相渗流及其试井分析普遍应用单项渗流方法的现状值得注意。对溶解气驱油藏指出:产能分析8种方法中以修正、改进的无因次IPR曲线和模拟方法、压力分析3种方法中以两相拟压力与平方压力方法是目前主要应用和研究方向;相渗和两相拟压力函数的计算是关键问题。From the two aspects of multiphase flow through porous medium classification and oil & gas two phases flowing through porous medium of solution gas drive reservoir, this paper sums up and evaluates the situation of well testing analysis research, the situation of that there are many multiphase flow through porous medium such as oil and gas, oil and water, gas and water two-phase, oil and gas and water three-phase in oil & gas field of china and one phase flow through porous medium method applied in well testing analysis. In the solution gas drive reservoir, it also points out that in eight kinds of production potential analysis methods, clarified and modified dimensionless IPR curve and simulation method and, among three kinds of pressure analysis method, two-phase pseudo-pressure and square pressure method are main application and research direction. Calculating of relative permeability and two phase pseudo-pressure function are critical problems.
