摘要：In this paper, the potential seven sets of geothermal resources in the Sichuan Basin were evaluated by using amethod for rapidly calculating geothermal resources in the sedimentary basins by multi data fusion, and suggestions on geothermal development and utilization are made based on the basic characteristics of abandonedwells in the oil and gas fields. The results show that the Sichuan Basin is rich in geothermal resources. The totalresources of 7 sets of thermal reservoirs reach 4.26 × 1013 GJ, of which the Qixia-Maokou Formation has thelargest potential geothermal resources, reaching 1.36 × 1013 GJ. The Permian Qixia-Maokou Formation insouthern Sichuan Basin has the conditions to prioritize the development of geothermal resources and has thecharacteristics of the highest temperature of formation water and the largest current and cumulative waterproduction. At the same time, according to the formation temperature of abandoned oil and gas wells, they aredivided into two types of wells, and different geothermal resource utilization methods are proposed. The researchresults can provide a model for the evaluation of geothermal resources in sedimentary basins and a resource basisfor the development of geothermal resources in the Sichuan Basin.
