Abstract
Disclosed is a fracture plugging simulation experimental device and an experimental method thereof. The device comprises a simulated wellbore, a simulated formation, a simulated fracture, a plurality of pressure sensors and vales, a mixing barrel, a liquid injection port and a pressurization port, a liquid collection tank, a plugging fluid storage tank, a heating device, etc. The method comprises: loading the simulated formation with the simulated fracture in the simulated wellbore, closing the second valve and turning on the mixing device, injecting a lost circulation material into the mixing barrel, closing the liquid injection port and turning on the heating device and pressurizing, stopping pressurizing and opening the second valve to establish a plugging process, turning on the plunger pump to continue pressurizing, and collecting a fluid pressure change of the simulated fracture in the plugging process; and calculating a pressure-bearing capacity of plugged fracture.
