摘要(Abstract):

本文研究了单一介质中非达西低速渗流时,关于续流和表皮效应的影响,并建立了它的数学模型。对定解问题(1.14)~(1.18)式用拉氏变换求解,拉氏空间的特解用格林函数表示,再进行拉氏逆变换,求得了它的解。从试算中发现,能得到驼峰型压力曲线。
In the paper, the influence of the after flow and skin effect for non-darcy flow at low velocity through single medium is studied and a mathematical model is developed. The Laplace Transform is used for the definite solution problems (1.14)~(1.18). The special solutions of Laplace space are expressed by the Green Function, and then the Laplace inverse transform is used for their solutions. From trial calculations, it is found that humped pressure curves can be obtained.
