Water injection well transformation simulation experiment device and method

The invention provides a water injection well transformation simulation experiment device and method, and belongs to the field of petroleum and natural gas. Simulating a vertical shaft; a core holder; the measuring end of the pressure measuring device is located in the overflowing cavity, and the pressure measuring device is used for measuring the pressure change in the overflowing cavity. Liquid is supplied to the simulation vertical shaft through the working liquid supply device, due to the fact that the multiple core holders are arranged, multiple different permeation cores can be installed in the core holders, the fracturing and acidification process in a well is truly simulated, the simulation vertical shaft finally supplies working liquid to the core holders through the multiple through holes, and the experiment is completed. The device can be used for truly simulating the water injection and transformation process of the deflagration fracturing, acidification and perforation water injection well, and h
