摘　　要：本文利用油藏渗流力学原理,结合留数方法和Bessel函数理论,求出了气水两相流不稳定试井模型在实空间的解析解以及其早期解和晚期解的渐近表达式,绘制了无因次样板曲线。该方法可用于求无穷双孔介质油藏、多层油藏、复合油藏等试井模型在实空间的解析解,对试井分析有理论应用价值。According to the permeation fluid mechanics of oil reservoir, residue method and bessel function theory, this thesis gets the analytic solution of well test model with gas and water two-phase flow. Moreover, the asymptotic expression in early stage and late stage is offered,and the dimensionless type curve is plotted too. The results can be applied for getting the analytic solution of well test model for the infinite dual porosity reservoir, mult-layer reservoir, compound reservoir, and have an applicable value in well test analysis.
