摘　　要：地热能是一种可再生清洁能源,能源利用系数达73%,远高于太阳能和风能等常规清洁能源。中国石油所属油区蕴藏大量地热能资源,仅大庆油田、华北油田、辽河油田三家油田蕴藏的地热资源总量达10 934×10^(18)J,可采资源总量达425×10^(18)J,是当年中国石油能源消耗总量的200多倍。中国石油各油气田开展了大量地热发电、地热供暖、地热养殖等地热利用项目,积累了丰富的经验。在此基础上,进一步扩大地热资源利用,在地热能资源条件较好的地区开展双工质循环地热发电,在生产站场开展地热能直接利用替代站内用热负荷,在集中矿区开展地源热泵直接利用等,可有效降低企业生产成本,同时探索形成油田新的经济产业链,为油田实现绿色发展、可持续发展奠定基础。Geothermal energy is a renewable and clean energy source with an energy utilization factor of 73%,far higher than conventional clean energy sources such as solar and wind energy.The oil fields in CNPC jurisdictions contain a lot of geothermal energy resources and geothermal energy in Daqing,Huabei and Liaohe oil fields reaches 10 934×10^(18) J and total recoverable geothermal energy is 425×10^(18)J,which more than 200 times of CNPC’s total energy consumption.CNPC carries out geothermal power generation,geothermal heating,geothermal cultivation and other geothermal projects and has rich experience in developing geothermal energy.On this basis,further utilization of the geothermal resource,eg,developing geothermal water and steam for power generation,replacing the hot medium with hot water,or pumping the geothermal water for direct use can effectively reduce the production cost,at the same time explore new economy industrial chain,which will lay a good foundation for the green and sustainable development of oilfield.
