The invention discloses a device for simulating two-dimensional filtration of fracturing fluid. In the device, a liquid storage tank is communicated with a fracturing fluid inlet at the upper end of acore holder, and a hydraulic pump is arranged on a communicated pipeline; an oil storage tank is communicated with a confining pressure cavity of the core holder, and a confining pressure pump is arranged on the communicated pipeline; a weighing device is positioned at the lower part of the filtrate outflow device at the lower end of the core holder. According to the invention, the filtrate inflow and outflow channels are arranged in a drilling core, so that not only can static filtration of the fracturing fluid be realized, but also dynamic filtration can be simulated, and the dynamic filtration simulation process can truly reflect the shearing action of the axial flow of the fracturing fluid on the filter cake on the surface of the inner wall of the core. According to the invention, thehydraulic pump, the confining pressure pump and the weighing sensor are all connected with the computer control system, and the computer control system can conveniently control the hydraulic pressureand the confining pressure, and simultaneously, the data of the weighing sensor is automatically read, so that the repeated labor and the human error of manual reading can be reduced.
