摘要

This paper analyzes the application of regional aeromagnetic data in studying regional geothermal field, and put forward the method of calculating geothermal gradient on the base of well temperature data by using exponential form, establishing a relationship between Curie depth and near-surface geothermal gradient, as well as the index factor, and giving out the method and formula to obtain near-surface geothermal gradient. Through the analysis of regional geothermal field calculation result in northern Songliao basin, it is considered that by combining measured aeromagnetic data with a certain amount of well temperature data we can predict the regional geothermal field better, and also provide more reliable temperature data evaluation of the basin.
