Temporary plugging agent crack plugging pressure-bearing experimental device

The invention provides a temporary plugging agent crack plugging pressure-bearing experimental device. The device comprises a pressure pump, a first container, a second container, a crack plate mold, a pressure detection element and a valve; a piston is arranged in the first container; the piston divides the first container into a first chamber and a second chamber which are independent; the first chamber accommodates a fluid medium; the second chamber accommodates a fracturing base fluid; the pressure pump is communicated with the first chamber; the second container is communicated with the second chamber; the second container is used for containing a temporary plugging agent; a simulated crack connector is formed in the bottom of the second container; the crack plate mold is installed at the simulated crack connector; a wedge-shaped liquid channel is formed in the crack plate mold; and the pressure detection element communicates with the second chamber and is used for monitoring the pressure of the second c
