Wall adhesion test device and wall adhesion test method for gas-dissolved oil-water mixed solution

The invention provides a wall adhesion test device and a wall adhesion test method for a gas-dissolved oil-water mixed solution, and belongs to the field of oil field oil-gas gathering and transportation. The wall adhesion test device comprises a stirring tank, a first flow meter, a first pump, a test pipe, a gas-liquid separator, a gas storage tank, a first valve, a second valve, a third valve, an oil supplementing tank, an oil supplementing pump, a first pressure gauge, a second pressure gauge, a first thermometer and a second thermometer; the oil supplementing tank and the oil supplementingpump are arranged; the oil supplementing pump is used for supplementing oil to the stirring tank; the loss of oil in the test tube is compensated, so the water content of the oil pumped by the firstpump can be kept stable; and after natural gas separated by the gas-liquid separator enters the gas storage tank, the natural gas is pressurized, and the natural gas is supplemented into the oil-watermixed liquid pumped out by
