Research and Analysis On Drilling Logging Curve and Geological Characteristics of Dry Hot Rock In Gonghe Basin,china

Dry hot rock resource has the advantages of clean, renewable, high utilization coefficient and low carbon dioxide emission. It is a strategic alternative resource with great development prospects. Drilling is the most direct technical means to obtain the physical data of dry hot rock and master the geothermal and geological parameters. It is also the only way to establish the channel of injection and production wells. In the process of dry hot rock drilling, the lithology, physical properties, resource reserves, resource distribution and exploitable parameters of the drilled formation can be measured through logging. Combined with the geological conditions of Gonghe Basin in Qinghai Province, this paper comprehensively analyzes the geophysical logging curve, combined with the original data such as geological logging and multi period unsteady temperature measurement, so as to provide scientific data for the study of the geological characteristics of Gonghe dry hot rock development site, provide a basis for the optimization of fractured intervals and favorable development areas, and provide theoretical guidance for the study of drilling wellbore stability and the optimization of wellbore structure in later development.
