A system for testing the sand suspending ability of fracturing fluid comprises two branches. The first branch comprises a first gas bottle and a second gas bottle which are connected with the inlet of a filter. The outlet of the filter is sequentially connected with a condenser, a storage tank, a first injection pump, a first pressure sensor, a first flowmeter and a first check valve. The second branch comprises a liquid container, a second injection pump, a second flowmeter, a piston container, a second pressure sensor and a second check valve which are sequentially connected. The two branches converges and then are sequentially connected with a safety valve, a middle container, a third pressure sensor, a seventh valve, a plunger pump, a third check valve, an eighth valve and a circulation loop. The circulation loop comprises a screw pump, a fourth pressure sensor, a temperature sensor, an observation container, a fifth pressure sensor, a spiral pipe and a ninth valve which are sequentially connected. By the system, the dynamic sand suspending ability and static sand suspending ability of various types of fracturing fluid can be tested, and the viscosity of various fracturing fluid can be measured through a falling-ball method.

A system for displacing shale gas with CO2 and simulating and testing adsorption and desorption of shale to the shale gas or CO2 comprises a CO2 bottle and a CH4 bottle, the CO2 bottle is connected to the input end of a first piston container, the CH4 bottle is connected to the input end of a second piston container, the power driving ends of the first piston container and the second piston container are connected with a power driving system, the output ends of the first piston container and the second piston container are connected to the input end of a sand-filled tube, a connecting pipeline for connecting the output ends with the input end is provided with a vacuum pump and a calibration system, the sand-filled tube is arranged in a thermotank and is connected with an axial pressure pump, the output end is connected to a tail gas recovering bottle, and a pipeline for connecting the output end with the tail gas recovering bottle is provided with a back pressure control system and an infrared gas analyzer. The invention also provides a method based on the system. The system and the method can simulate and test the effect of displacement of the shale gas with CO2 in different states at different temperatures under different pressures; and an experiment device is used to carry out experiments of adsorption and desorption of the shale to CH4 or CO2 and research the gas adsorption and desorption rule of the shale at different temperatures under different pressures.
