Technical Field
The invention belongs to the technical field of geothermal resource development, and relates to a device for constructing dry-hot rock heat storage by experimentally simulating multi-type fluid fracturing.
Background
Geothermal resources are used as a clean renewable energy source with high competitiveness and play an important role in dealing with global climate change, energy conservation, emission reduction and haze treatment. Hot dry rock refers to rock (body) that is hot in the earth but lacks fluid or a small amount of fluid due to low porosity and low permeability, and the heat stored in hot dry rock needs to be recovered by artificial fracturing to form an Enhanced Geothermal System (EGS). The dry hot rock is different from a hydrothermal geothermal rock stratum and has the outstanding characteristics that a reservoir is compact, does not contain or contains a small amount of fluid, and needs to be fractured to store and take heat. In hot dry rock geothermal development, a place where heat exchange can be performed, namely a fracture system with high permeability, is usually formed in a deep high-temperature heat storage rock stratum through hydraulic fracturing and the like. During production, low-temperature water is injected into the injection (recharge) well to exchange heat with surrounding rocks to generate high-temperature and high-pressure water or a water-vapor mixture, and the high-temperature and high-pressure water or the water-vapor mixture is produced in the production well and is used for direct heat supply or power generation.

In addition, CO2As greenhouse gas, large-scale emission can cause serious environmental damage, cause temperature rise and sea level rise, and carbon dioxide can be sealed in an underground reservoir by fracturing geothermal media such as dry hot rocks, and the like, thereby being feasible to reduce CO2A method of venting.
At present, hydraulic fracturing is mainly adopted for hot dry rock fracturing, carbon dioxide, nitrogen and the like are not applied to hot dry rock fracturing, fracturing effects of different fluid components under different geological backgrounds are unclear, fracturing engineering factors such as discharge capacity and concentration have undefined influence on crack development after fracturing, and related simulation experiment equipment is lacked.
