摘要
The main heat reservoirs in Dongpu depression include Neogene Minghuazheng Formation, Paleo-gene Guantao Formation and Dongying Formation clastic rocks and Ordovician carbonate rocks. However, there is a lack of research on the temperature distribution of each heat reservoir, which restricts the evaluation of geothermal exploration and development in this depression. In this article, therefore, geothermal gradient and heat flow and thermal physical parameters of rock, on the basis of using one dimensional steady state heat conduction equation to calculate the guantao in the study area at the top and bottom of the heat storage temperature, the top surface temperature at 63˚C~106˚C, west slope belt, concave temperature are high and the central uplift belt, eastern time concave and LAN chat fault zone temperature are low; the temperature of the bottom surface is between 65˚C and 120˚C, and the heat storage temperature in the south is higher than that in the north. Guantao Formation has high sandstone content, high porosity and high permeability, which can form several types of heat reservoirs and develop medium-low temperature geothermal energy. It is an ideal place for developing medium-low temperature sandstone geothermal energy. The research results of this paper can provide important heat storage information for geothermal exploration and development of Guantao Formation in Dongpu depression.
