"双碳"目标下,2021年冀东油田在山东省德州市武城县建设了首个中国石油域外清洁能源地热供暖项目,建成集中供暖面积235×104m2,后期扩建至310×104m2.文章从地面工程建设布局、抽水回灌试验及实施效果、地质资源评价体系、"6类18项"地热能开发技术运用,以及管理经验等方面进行分析,认真分析武城县地热地质情况,通过地热资源评价,合理制定及实施采灌试验,依托中国石油勘探开发、地质评价及工程建设等地热能开发利用技术优势,进行地热开发工程建设,达到项目建设运行效果,实现政府民生供暖项目保障要求,满足各项地热开发利用规范标准.该项目每年供热量55.656×104GJ,折合标准煤5.417×104t/a,减排CO2量3.7919×104t/a,为成功实施城区集中供暖清洁替代探索出一条可行路径.
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.
