Abstract
Disclosed is a device for evaluating damage of fracturing fluid to reservoir and operation method thereof, the device includes a liquid storage tank, a suction tube, a chromatography device, a bracket, a receiving container and a height adjuster; the disclosure has the following beneficial effects: since different liquids pass through the porous medium at different time and speed and the silica gel particles will not expand when immersed in the liquid, a porous structure is formed by placing silica gel particles of different sizes to simulate the pore-throat structure of unconventional oil and gas reservoirs, hence removing the influence of fracturing fluid on the hydration and expansion damage of the reservoir matrix, by testing the time and flow rate of different fracturing fluids flowing through the silica gel pores, the degree of damage caused by fracturing fluids to unconventional oil and gas reservoirs is evaluated.
