The invention discloses a double-barrel efficient friction thermal desorption device for shale drilling cuttings in oil and gas drilling, and the three-dimensional structure of the double-barrel efficient friction thermal desorption device is shown in the abstract attached drawing. The device mainly comprises an oil-containing drilling cutting feed port, a second cylinder wall, a steam backflow layer, a power shaft, a dry drilling cutting discharge port, a steam outlet, a spiral friction strip, outer blades, a first cylinder wall, inner blades, a steam inlet, a steam drilling cutting outlet and a coaxial device, the steam backflow layer heats shale drilling cuttings, and the power shaft drives the inner blades and the outer blades of the double cylinders to hammer and grind the oil-containing drilling cuttings at the same time. A spiral friction strip is welded to the inner side of the second barrel wall, and the double-barrel inner and outer blades are in the shape of a trapezoid with the narrow inside and t
