The article deals with the solution of hydrodynamic issue of liquid inflow to three-bored horizontal well, operated in layer-inhomogeneous formation. The case, when in the formation, consisting of three layers with different permeability thickness and coefficients, one three-bored horizontal well is operated, the bores of which are located free in formation layers, is considered. Provided formula enables to define the debit of three-bored well, when its bores are located free (i.e. in one layer) or when they are operated in different layers of formation.
