Core Viewpoint - China Petroleum & Chemical Corporation (Sinopec) has made significant progress in the industrial application of geothermal resources in the oil and gas sector, particularly through the successful energy transformation at the Gudong Oilfield's Dongyi Joint Station, which utilizes waste heat from oil extraction to replace traditional gas heating [1][2]. Group 1: Project Achievements - The Gudong project employs a dual heat source technology that combines high-temperature waste heat from gas wells and medium-temperature waste heat from oil wells, achieving an annual clean heating capacity of 209,000 GJ and reducing heating costs by 59% [1]. - The project replaces 6.38 million cubic meters of natural gas, sufficient to meet the annual gas needs of approximately 20,000 urban households, and contributes to a reduction of 13,500 tons of CO2 emissions annually [1]. Group 2: Geothermal Resource Utilization - The Jiyang Depression, where the project is located, has a total geothermal resource equivalent to about 25 billion tons of standard coal, with an average geothermal gradient of 3.4-4.2 degrees Celsius per 100 meters, making it a typical geological structure for both oil and heat [1]. - A total of 51 geothermal waste heat utilization projects have been established in recent years, revitalizing 25 abandoned wells and achieving an annual clean heating capacity of 3.46 million GJ [1]. Group 3: Future Development Plans - Sinopec's Shengli Oilfield has set a development strategy to build a clean energy system by integrating sources, usage, and storage, aiming to transition from a traditional oil and gas producer to a diversified green energy supplier [1]. - The Shengli Oilfield plans to achieve large-scale green heat replacement in its collection and transportation systems, economic replacement in its oil extraction systems, and breakthroughs in its steam injection systems by 2028, exploring new pathways for the green transformation of traditional energy enterprises [2].
