Research Of Hot Dry Rock On Fracture Temperature Distrbution In Shenyang

With the implementation of the concept of sustainable development, mineral of non-renewable resources scarcity and environmental problems increasingly serious change, a new type of green resources development has become the urgent problems. Hot air rock as a kind of large storage capacity, development restricted less, green pollution-free new geothermal resources, because of its characteristics is suitable for application in northern cold heating demand, thus can reduce because of cold heating caused by the mineral resource consumption and reduce environmental pollution problems. In the use of hot air rock heating the whole big proposition in the study of the key technology for hot air rock retention layer crack temperature distribution, here we use finite element related theory, based on the heat transfer and heat transfer theory as the foundation, the establishment of hot air rock retention layer a single crack model, through the software Fluent carry on the simulation. And in the process of simulation in shenyang special geological conditions and heating requirements will dry rock heating system parameters determined respectively for drilling depth of4000meters, the flow speed of1cm/s. And on this basis the retention layer crack temperature distribution were analyzed, and through the data calculation, statistics, that integration formula.For the application of shenyang area hot air rock retention layer temperature distribution calculation and prediction. Reuse the foreign development of data, and the corresponding simulation results, in heating standard based on the heating dry rock ability and heating the ability to carry on the estimate, roughly determined the single ported out well in shenyang area can meet the90000square meters of heating demand.
