Coupling Discipline Analysis of Reservoir Deformation, Seepage and Pitshaft Pressure Drop
The coupling among reservoir deformation, fluid seepage and pitshaft pressure drop is closely related with productivity predicting and pipe wall stability of horizontal well. This text considers interaction among reservoir deformation, radial seepage and variable mass flow, establishing coupling mechanical-mathematical models, decoupling the coupling model, conducing to the analytic solution of pore pressure, mainly analyzing the influence of physical-mechanical nonlinear property of reservoir deformation on pore pressure and the influence of radial seepage on pressure drop of horizontal well. It shows, nonlinear property of Reservoir changes obviously, pore pressure dissipating slowly; On calculating pressure drop of horizontal well, we should consider the seepage influence on main stream flow, and the influence is so obvious; The difference between coupling and uncoupling is so great, thus we can not neglect the coupling effect.
