摘要（英）：

The invention discloses a high-temperature high-pressure alternate-injection acid liquid distribution simulation device comprising a liquid tank, a feeding pipe, a constant-flux pump, a fracturing liquid valve, a fracturing liquid tank, an acid liquid valve, an acid liquid tank, a pressure gauge, heating bars, a temperature sensor, a rear cover plate, a front cover plate, an observation window and a waste liquid tank. The liquid tank is connected to an inlet of the constant-flux pump through the feeding pipe; an outlet of the constant-flux pump is connected with the fracturing liquid valve and the an acid liquid valve, the acid liquid valve and the acid liquid tank are connected in series, the fracturing liquid valve and the fracturing liquid tank are connected in series, and the fracturing liquid tank and the acid liquid tank are connected in parallel and then connected to the rear cover plate; the rear cover plate is provided with the pressure gauge and the temperature sensor; a row of small holes are drilled in the top face of the rear cover plate, heating bars are mounted in the holes, and the number of the heating bars is determined by the device size; the front cover plate is provided with the observation window which is glass plate, and the acid liquid distribution form is observed through the observation window; and the other end of the rear cover plate is provided with a waste liquid tank used for recovering experimental waste liquid.
