Abstract The sedimentary basins inside five tectonic units in Henan Province, involving 11 cities and more than 60 counties, is the main areas where geothermal resources occur. Analysis of 524 geothermal wells in the five tectonic units shows that the geothermal wells are unevenly distributed in different units, and the depths of water taking layers in the wells vary greatly. The average water taking depths of the five tectonic units provide a basis for the designing of geothermal wells in these areas. The distribution statistics of geothermal wells in the five tectonic units show that the distribution density in three units is less than 0.9 wells per 100 km2, with great potential for exploration.
