Liquid shear testing device for simulating well cementation cement slurry mixing environment

The utility model relates to the technical field of petroleum drilling, and discloses a liquid shear test device for simulating a well cementation cement slurry mixing environment, which comprises a test box and a cover plate, the test box and the cover plate form a closed space, a support wall is arranged in the test box, a partition plate is fixedly connected between the test box and the support wall, and the partition plate is arranged in the closed space. The space between the test box and the supporting wall is divided into a simulation cavity and a test cavity through a partition plate, and the side surface of the test box is fixedly connected with a conveying pipe. According to the utility model, the two partition plates are arranged and are used for dividing the cement sheath into the simulation cavity and the test cavity, the simulation cavity can be used for supporting the cement sheath, the anti-shearing force of the cement sheath can be tested by pressurizing the test cavity, the axial pressure ca
