“…The central Australian Warburton-Cooper-Eromanga basins host one of the most prospective hot dry-rock geothermal resources in the world as well as significant onshore hydrocarbon resources related to from unusually high palaeo-and current heat-flow (Deighton and Hill, 1998;APPEA, 2003;Hillis et al, 2004). To date, little is known about the timing and extent of palaeotectonism controlling the thermal history of these basins.…”

“…Among geothermal resources, hot dry rock (HDR) is the high-temperature rock mass with the largest reserves and the most promising geothermal resources, which is at a general temperature over 200℃ , a buried depth of 3-10 km, and with little fluid [1][2][3]. The development and utilization of hot dry rock requires artificial reservoir and extraction of heat from rock mass by heat exchange [4][5][6], which is also called Enhanced Geothermal Systems, EGS. The research on hot dry rocks began in the United States in the 1970s, and then many countries successively carried out scientific research on hot dry rock.…”

Hot dry rock resources as one of the most promising clean energy in the future, with large reserves, renewable and other advantages, since the 1970 s, many countries all over the world have explored and practiced a lot on the exploration and development of hot dry rock resources, however, few studied the heterogeneity of the rock and the underground geologic structures of hot dry rock resources influence domain enrichment regularity of heat transfer mechanism. Therefore, this article considered the thermal conductivity of rock anisotropy, and set up a horizontal stratum and a fold strata 2D geological model, through numerical simulation with the field rock samples indoor triaxial rock thermal conductivity test results, introducing the thermal conductivity of rock anisotropy index A = K vertical bedding/ K parallel bedding and analyze the underground geologic structures’ influence on heat transfer in the rock. The results show that the anisotropy of rock thermal conductivity has no influence on the heat transfer process in underground rock strata when the rock layer is horizontal, which can be regarded as one-dimensional multilayer wall heat transfer. Fold structure will influence the underground heat transfer direction, so it is not simply seen as a one-dimensional multilayer flat wall heat transfer process in numerical simulation. At the inclined interface of rock strata, "heat flow refraction" usually occurs, which further affects the direction of heat transfer. As a result, heat is concentrated in the syncline of the fold structure in the deep and anticline in the middle and deep layers, while the temperature distribution in the shallow layer is almost unaffected by the structure. The research results of this paper are of great significance to the delineation of the target area and the development and utilization of the hot dry rock resources.

“…There is also a much larger volume of resources that are technologically more difficult to access. Over time, resources near the top of the pyramid are depleted and technological developments lead to resources further down the pyramid being developed cost effectively (Hillis et al, 2004).…”

Petrophysical investigations are fundamental to natural resource exploration. In order to recognise the geothermal potential of sedimentary rocks in central Poland, 259 samples were collected from prospective deep-lying geothermal reservoirs. Parameters measured include bulk density, skeletal density, effective porosity, permeability, average pore diameter and specific surface. Results indicate that at great depths (mostly > 3,000 m below surface) sedimentary rocks show low values of porosity (mainly less than 5%) and permeability (only sporadically in excess of 1 md). These values call for a petrothermal use of reservoirs, for which an Enhanced Geothermal System (EGS) was developed. Reservoirs suited for the EGS are Carboniferous and Lower Triassic sandstones in the central part of Poland (Mogilno-Łódź Trough region and a small part of the Kujawy Swell and Fore-Sudetic regions). In addition, Carboniferous limestones in this area are potentially prospective.
