Exploration and Evaluation of Geothermal Resources in Shenheyuan of Shaanxi Province
摘要
Abstract
Shenheyuan is located in the Guanzhong Basin,with abundant geothermal resources.This article aims to explore and evaluate the geo-thermal resources in a certain area of Shenheyuan,providing a basis for later heat exchange calculation and design.By collecting data and con-ducting on-site investigations,the geological characteristics,geological structures,and thermal storage characteristics of the exploration area are identified.High precision temperature measuring optical fibers are used to measure well temperatures,and the geothermal gradients of each ther-mal reservoir layer are obtained through linear regression.Through comprehensive geological analysis and thermal storage methods,the geothermal resource reserves of a single geothermal well are calculated.The results show that the calculated average geothermal gradient is3.26℃/100 m,which is close to other geothermal wells in the area.The distribution of geothermal resources in this area is uniform,and the geothermal gradient does not change much;The geothermal resource reserve of a single geothermal well is approximately 8.21×1015 J.Geothermal exploration provides a basis for the subsequent development and utilization of geothermal energy.关键词
