The invention provides a laboratory experiment device and method for solid fluidization exploitation of a gas hydrate. The laboratory experiment device comprises a sea water injection device, an excavation experiment main body module and an experiment data information sampling module. According to the laboratory experiment device and method, a cutter is directly utilized for mechanical crushing of hydrate sediment under the circumstance that the temperature pressure in an exploitation kettle is the same as the actual pressure at the sea bottom, and sea water is injected into the exploitation kettle to ensure that the crushed hydrate particles flow together with the sea water, so that the phase change, the particle diameter distribution and the fluidization effect of the hydrate during mechanical crushing can be simulated, and a theoretical support is provided for solid fluidization exploitation of a non-diagenetic hydrate.

The invention discloses a high-pressure low-flow rock core displacement pump based on a rock laboratory experiment. A servo motor is connected with the high-speed end of a harmonic gear reducer, and the low-speed end of the harmonic gear reducer is connected with a screw rod through a torque limiter. A bearing sleeve is installed between the screw rod and a shell body. A nut is installed on the screw rod in a sleeving mode, and a piston is installed on the nut in a sleeving mode. The shell body is provided with a long-strip-shaped guiding hole. A cam bearing is arranged between the piston and the shell body. The screw end of the cam bearing is fixedly connected to the piston. The roller end of the cam bearing is located in the long-strip-shaped guiding hole. A sealing sleeve is installed on a piston rod in a sleeving mode. One end of the piston rod is fixedly connected with the piston, and the other end of the piston rod is located in a cylinder body. The shell body is fixedly connected with the cylinder body through the sealing sleeve. Sealing rings are installed between the shell body and the sealing sleeve as well as between the cylinder body and the sealing sleeve. The cylinder body is provided with a low-pressure liquid suction opening and a high-pressure liquid discharging opening which both communicate with an inner cavity of the cylinder body. The high-pressure liquid discharging opening is connected with a pressure sensor. The servo motor conducts feedback control through pressure data sensed by the pressure sensor.
