Abstract

Abstract:

It is well known that the oil rate of horizontal well is much higher than that of vertical well in dual porosity reservoir.Transient test is an important means of obtaining reservoir parameters and identifying reservoir type. This paper presents a mathematical model of 3D horizontal well with wellbore storage and skin effect in dual porosity infinite and box-shape reservoir. The mathematical model is solved by means of Laplace transform. Based on the model presented above, the transient test data from an example horizontal well has been studied to produce fracture permeability, skin factor, wellbore storage coefficient, storativity -ratio and inter-porosity flow coefficient. The results show that the theory and method presented in this paper are reliable and applicable.

Key words: multiple media, oil reservoir, horizontal well, mathematical model, transient test interpretation
