• The Dongying geothermal resources are an important part of the deep geothermal resources in Tianjin Binhai New Area, and these resources will determine whether the demand target can be met. There is an urgent need to find favorable target areas for Dongying geothermal resources and to develop Dongying geothermal resources safely, stably and efficiently. The recoverable potential of the Dongying geothermal reservoir in different positions is calculated by simulating and predicting the water level, which is as an important index of zoning evaluation. By using the analytic hierarchy process (AHP), the comprehensive indexes of geothermal exploration and development regionalization are quantified. A grade-two evaluation system, which considers the development constraints, has been established for the delineation of deep geothermal resources’ exploration and development prospect target areas. The zoning evaluation results show that the excellent prospect target area of Dongying geothermal resources, for their exploration and development, is 314.33 km2, the general prospect target area is 745.77 km2, and the bad prospect target area is 879.31 km2. The quantitative zoning evaluation method can provide references for the optimization of the exploration and development target area of deep geothermal resources with low prospecting accuracy in key areas of China.
