In order to improve the validity of the previous models on calculating flow pressure for oil well with partially perforating fracture, a new physical model that obeys the actual heterogeneous reservoir characteristics was built.
Different conditions, including reservoir with impermeable top and bottom borders or the reservoir top which has constant pressure, were considered.
Through dimensionless transformation, Laplace transformation, Fourier cosine transformation, separation of variables, and other mathematical methods, the analytical solution of Laplace domain was obtained.
By using Stephenson numerical methods, the numerical solution pressure in a real domain was obtained.
The results of this method agree with the numerical simulations, suggesting that this new method is reliable.
The following sensitivity analysis showed that the pressure dynamic linear flow curve can be divided into four flow streams of early linear flow, midradial flow, advanced spherical flow, and border controlling flow.
Fracture length controls the early linear flow.
Permeability anisotropy significantly affects the midradial flow.
The degree of penetration and fracture orientation dominantly affect the late spherical flow.
The boundary conditions and reservoir boundary width mainly affect the border controlling flow.
The method can be used to determine the optimal degree of opening shot, vertical permeability, and other useful parameters, providing theoretical guidance for reservoir engineering analysis.
