Gas-water two-phase flow guide capability testing system of shale gas pressure crack net and testing method

The invention discloses a gas-water two-phase flow guide capability testing system of a shale gas pressure crack net. The gas-water two-phase flow guide capability testing system comprises a flow guide chamber, a three-way valve, a gas-liquid separator, a flow meter, a weighing device, a No.1 high-pressure reaction kettle and a No.2 high-pressure reaction kettle, wherein the flow guide chamber comprises a flow guide chamber body, a main flow guide silicone hose which is mounted in a hollow chamber in the flow guide chamber body and a plurality of secondary flow guide silicone hoses which are communicated with the main flow guide silicone hose along the length direction of the main flow guide silicone hose according to a pre-set angle; and the main flow guide silicone hose is communicated with an entrance and an exit of the flow guide chamber body. The main flow guide silicone hose for simulating main cracks and the secondary flow guide silicone hoses for simulating secondary cracks are put into the flow guide
