The invention provides a segmented oil extraction pipe column of a heavy oil horizontal well. Relates to the technical field of petroleum. The segmented oil extraction pipe column of the heavy oil horizontal well comprises a central pipe, a first flow passing hole is formed in the central pipe, and the first flow passing hole is communicated with a pipe cavity; the hydraulic control setting mechanism is arranged on the central pipe; a first overflowing hole is formed in the pipe wall of the central pipe, a flowing channel is defined by the pipe wall of the central pipe, and the flowing channel is communicated with a pipe cavity of the central pipe through the first overflowing hole, so that liquid can enter the flowing channel from the first overflowing hole, and then the hydraulic control setting mechanism is driven to conduct setting; and the electric control oil inlet mechanism and the hydraulic control setting mechanism share the flow passing channel and the first flow passing hole so as to control connec
