| 摘 要： | 针对双渗介质油藏,建立了考虑有效井筒半径和井筒储集效应的试井分析模型。利用拉普拉斯变换,在拉普拉斯空间中得到了储层压力和井底压力的无因次表达式;又根据相似结构理论,发现在不同外边界条件下的解式具有统一的结构。

| Abstract: | Aiming at dual-permeability media reservoir,a model for non-linear seepage of dual-porosity media reservoir was established in this paper.In the model,the effective wellbore radius and well bore storage is taken into consideration in the case of variable flow rate.By using Laplace transform,the nondimensional expressions of reservoir pressure and bottom hole pressure are obtained in Laplace space.And it is found that there is a similar structure among the expressions of solution under different outer boundaries. |

| Keywords: | dual-permeability media reservoir effective well bore radius variable flow rate similar structure kernel function |
