The utility model relates to a viscous crude lifts defeated viscosity reduction system of synthesizing of collection, including the beam -pumping unit with add the medicinal cupping, oil pipe is arranged in sleeve pipe in the pit, and the left and right sides of sleeve pipe upper end cross is connected with the sleeve pipe gate respectively in the pit, and oil pipe's upper portion is connected with the oil pipe gate, and the oil pipe gate links to each other with the defeated collecting main of collection, and the outside of sleeve pipe gate is connected with with the medicine check valve, andthe entry that adds the medicine check valve links to each other through the bottom that adds pencil and adding drugs control valve and add the medicinal cupping, and the top that adds the medicinalcupping is connected with balanced valve, medicament impregnation valve and adds the medicinal cupping water filling port, excavate one side of beam -pumping unit has small -size water supply well, and the immersible pump exit linkage of small -size water supply well bottom has clean water pipe, and clean water pipe links to each other through adding the medicinal cupping water injection valve andadding the medicinal cupping water filling port, clean water pipe still links to each other through the cooling water inlet of hot -water heating stove water intaking valve with the hot -water heating stove, and the hot water exit linkage of hot -water heating stove has the hot -water line, and the export of hot -water line is passed through the hot water check valve and is linked to each other with the defeated collecting main of collection. This system's viscosity reduction is effectual, easy and simple to handle.
