According to the system, a base is assembled at the lower end of an oil injection barrel, a piston is assembled in the upper space of the oil injection barrel in a sliding mode, an upper pressing head and a lower pressing head are connected to the piston and the base respectively, and a combined type circulating pipe and a sample are assembled between the upper pressing head and the lower pressing head respectively; the heat shrink tube is sleeved outside the sample; the hydraulic oil source supplies oil to the confining pressure loading cavity through a second three-way valve via a second oil passing channel in the base. An etchant solution is supplied into an inner cavity of the composite circulating pipe through a three-way valve I, a ventilation water passage I in the piston and a passage of the axis of the upper pressure head; and the air blower supplies high-speed air flow into the inner cavity of the combined type circulating pipe through the three-way valve. The method comprises assembling the test sy
