| Abstract
|
:
|
A two-layer reservoir with crossflow was erroneously taken as a dual-porosity, dualpermeability naturally fractured reservoir in the literature, and the solutions obtained from dual-porosity, dual-permeability model cannot account for the characteristics of two-layer reservoir. This study presents a new mathematical model and an analytical solution to the pressure transient equation of a uniform-flux vertical well in a two-layer reservoir with crossflow. The pressure of a vertical well producing a two-layer reservoir with a constant rate is examined. The pressure response is observed in three stages: it is identical to the commingled system because of the crossflow is so weak at the production beginning that we can ignore it, transition stage and the late stage which is same as the homogeneous system. And what’s more important, we propose a parameter to describe the crossflow in a two-layer reservoir quantitatively. Similarly, the developing trend of the crossflow parameter can also be divided into three stages. Then the results are extended to the partially penetrating well. These solutions are obtained by using Laplace transform, double Fourier transform and Green’s functions method with numerical approximations. These solutions give results accurate enough for practical applications and allow estimating effects of formation properties on pressure behavior. These results can be validated by comparing with those obtained by Eclipse. For a specific situation, when all the corresponding parameters are identical in each layer, the proposed solution for a two-layer reservoir reduces to the solution for a single layer reservoir.
