Geothermal exploitation and injection indoor simulation experiment method and device

Abstract

The present application belongs to the field of geothermal energy exploitation and irrigation, and discloses a geothermal exploitation and irrigation indoor simulation experiment method and device. The method comprises the following steps: loading a core sample into a core holder; placing the core holder in a container with a constant temperature water bath environment and keeping the core sample above the water surface; covering the core sample with sand; injecting water from the first end of the core holder and controlling the flow rate of the injected water; collecting the injection pressure of the first end of the core holder and the production temperature of the outflowing water at the second end; and analyzing the injection and production temperature variation based on the flow rate and pressure of the water injected at the first end and the temperature of the outflowing water at the second end. The method and device of the present application simulate the thermal reservoir by combining a constant temperature water bath with a sand bath, which can better simulate the actual situation of the reservoir and provide support for the development and utilization of oilfield hydrothermal geothermal energy.
