Under the"dual carbon"goal,Jidong Oilfield constructed a clean energy geothermal heating project in Wucheng County,Dezhou City,Shandong Province in 2021,the first of its kind outside Petro China's business operating region.The project,when completed,heated an area of 235×104m2 and later 310×104m2 after expansion.This article analyzes layout of surface engineering construction,testing water-pumping re-irrigation and its results,the evaluation system for geological resource,application of geothermal development technologies in 18 items of six categories,and managerial experience.It also makes a careful analysis of the geothermal and geological conditions in Wucheng County.The irrigation test was reasonably arranged and carried out on the basis of geothermal resource evaluation.Engineering construction of the geothermal development project depended on CNPC's technological advantages of geothermal development and utilization in the areas of exploration and development,geological evaluation and engineering construction.The project achieved the operational results,satisfying the local government's heating demand for people's liveliness and various specifications and standards of geothermal development and utilization.This project can annually provide 55.656×104GJ of heat,equal to 5.417×104 tons of standard coal,and reduce 3.7919×104 tons of CO2.It opened up an applicable way to provide clean concentrated heating in urban areas.
