Abstract: To focus on the issue of high permeability flow channels developed upon long-term strong water erosion in offshore unconsolidated sandstone，the Barree-Conway model was employed to describe the highvelocity non-Darcy flow within flow channels. An iterative method was adopted for the strong nonlinearity caused by high-velocity non-Darcy flow. Then a pressure transient model of vertical injection well with multi flow channels considering high-velocity non-Darcy flow was obtained through line source，Laplace transformation and numerical discretization methods，and the typical pressure dynamic curves and related parameters were analyzed.The results show that：（1）The semi-analytical model for unstable well-testing in vertical injection well with multi flow channels considering high-velocity non-Darcy flow can effectively address both the development of multi high permeability flow channels and high-velocity non-Darcy flow within these channels，and the calculation results are more reliable.（2）The typical pressure curves of vertical injection well with multi flow channels can be divided into six flow stages：wellbore storage，transition flow，bilinear flow，linear flow，flow channel interference，and radial flow. When high-velocity non-Darcy flow is considered，both the early stage pressure and pressure derivative curves move up significantly，and the flow conductivity capacity of the multi flow channels near wellbore shift down significantly. As the numbers of flow channels increase，the pressure and pressure derivative curves decrease significantly，while the influence of high-velocity non-Darcy flow within the flow channels diminishes.（3）The model was successfully applied to the parameters interpretation of an injection well in Bohai Oilfield，then the quantitative characterization of flow channels can be achieved.

Key words: vertical injection well, large pore channel, high-velocity non-Darcy flow, line source, Laplace transformation, numerical discretization methods, well testing interpretation model, iterative method
