Casing buckling evaluation system in inclined shaft cementing process

The invention relates to a casing buckling evaluation system in an inclined shaft cementing process. The system comprises a well wall simulation unit and an inclination control unit, the well wall simulation unit defining a cavity to simulate a well wall, and the inclination control unit controlling the well wall simulation unit to be in an inclined state; a hollow sleeve extending into the cavity; a sleeve fixing device used for fixing the top of the hollow sleeve; a sleeve shoe, arranged at the bottom of the cavity and connected with the bottom of the hollow sleeve so as to seal the hollow sleeve; a Cement paste storage and collection device, a cement paste control valve being arranged on the cement paste storage and collection device so as to control cement paste in the cement paste storage and collection device to flow into the cavity; a well bottom sleeve, connected with the well wall simulation unit; an annulus pressure sensor; and a detection device, used for detecting the vertical tension, torque and
