The invention provides a sleeve shear deformation experimental device. The sleeve shear deformation experimental device mainly comprises a loading rack, a base, a fixing clamp, a connecting plate, a strain sensor, a shear clamp and a baffle, the baffle is connected with the fixing clamp through the connecting plate and used for limiting the axial displacement of the shearing clamp. The sleeve is arranged in the centers of the circular through holes in the fixing clamp and the shearing clamp and is coaxial with the fixing clamp and the shearing clamp; the strain sensor is arranged on the inner wall of the sleeve at the shearing part between the fixed clamp and the shearing clamp; when the loading rack applies a load to the shearing clamp, the shearing clamp shears the casing pipe, and the strain sensor is used for detecting the deformation condition in the shearing process. Sleeve shear deformation caused by stratum slippage can be simulated through a shear experiment on the sleeve, and the experiment device h
