The invention provides a horizontal well drilling borehole cleaning construction process method, and relates to the technical field of petroleum industry drilling engineering, and the horizontal well drilling borehole cleaning construction process method comprises the following steps: determining the viscosity of a drilling fluid according to the diameter of a borehole; according to the borehole diameter and the drill column diameter, the rotating speed of the drill column and the borehole cleaning displacement are determined; the drilling fluid circulation time is determined according to the horizontal well inclined depth and the hole drift angle; and borehole cleaning construction is conducted according to the rotating speed, the borehole cleaning displacement, the viscosity of the drilling fluid and the circulation time of the drilling fluid. By means of the horizontal well drilling borehole cleaning construction process method, the cleaning effect of a horizontal well borehole can be effectively improved.
