| 摘要: |
| 针对均质油藏球向渗流问题,研究了3种外边界(无穷大、定压、封闭)及内边界条件(引入表皮效应)下的定流量生产的问题,并建立了考虑二次梯度影响的不稳定渗流问题的试井分析模型,先对此模型作线性化处理,利用Laplace变换求得了线性化后的无因次储层压力和井底压力分布的Laplace空间解,在全面分析了它们之间内在联系的基础上,得到了此模型在3种外边界条件下解式之间的相似结构. |

| Abstract: |
| According to radial-spherical seepage problem in homogeneous reservoir,we studied constant flow production problem under three kinds of outer boundary conditions(infinite outer boundary,constant pressure and closed boundary)and inner boundary condition(sk |
