Research on Water Temperature Change of Hot Dry Rock Fracture Storage Layer in Shenyang

Abstract:

Hot dry rock(HDR) provides heat through fracture storage layer. The purpose of research on water temperature change of hot dry rock fracture is to study that whether heat energy can satisfy five months winter heating or not. Research method is establishing model of hot dry rock fractured storage layer by means of numerical simulation software FLUENT according to the rock physical properties in Shenyang region. The depth of drilling is 4000m and the water flow rate is 1cm/s. Research principle is high temperature underground rock transfer heat to medium water in the fracture by coupling. Conclude water temperature change equation every two weeks. The results of the study is that fracture water temperature distribution can be approximated taken as linear distribution. According to the slope K, we can conclude water temperature change formula(3.10), and we can use it to infer fracture water temperature.
