Abstract
The calculating speed of transient pressure response is always difficult point in application of transient well testing with vertical fracture.Combining three linear flow model with pseudo radial flow model is an effective method to solve this problem.This paper presents the curves among apparent skin factor Sa of pseudo radial flow,dimensionless flow,dimensionless fracture conductivity FCD and fracture skin factor Sf,and introduces a way to integrate two models.Analysls results on practical examples show that this method has advantages of the quick,convenient and useful.
