The invention relates to an anti-drag and anti-friction tool with a torsional coupling effect, and is used for increasing circumferential torsion and axial pressurization in a horizontal well with a long horizontal section. Through the technical scheme, the anti-drag and anti-friction tool with the torsional coupling effect mainly comprises a transmission shaft, a transmission shaft shell, a discspring assembly shell, a disc spring assembly, a piston sleeve, a power assembly, a movable valve component, an abrasion valve block, a static valve component and a lower joint; the transmission shaftshell, the disc spring assembly shell, the power assembly and the lower joint are in threaded connection from top to bottom in sequence, the transmission shaft is matched with an inner hole of the transmission shaft shell, and the upper end is in threaded connection with the piston sleeve; the disc spring assembly is mounted between a spacer sleeve and the piston sleeve; the movable valve component is in threaded connection with the lower end of the power assembly; the static valve component is mounted in the inner hole of the upper end of the lower joint, and the abrasion valve block is mounted in the inner hole of the upper end of the static valve component. The anti-drag and anti-friction tool has the advantages of good axial pressurization effect, high vibration capability, simple structure and the like, and the extending drilling ability of the horizontal well with the long horizontal section can be improved.
