Core Insights - China Petroleum & Chemical Corporation (Sinopec) has successfully transitioned the Dongyi Joint Station of the Shengli Oilfield to utilize heat from extracted fluids, replacing traditional gas heating methods, with an expected annual clean heating capacity of 209,000 GJ, equivalent to replacing 6.38 million cubic meters of natural gas and reducing CO2 emissions by 13,500 tons [1] Group 1: Energy Transition and Environmental Impact - The Shengli Oilfield has launched Shandong's first medium-deep geothermal project for oil and gas production, with an annual clean heating capacity of 75,000 GJ, marking significant progress in the industrial application of medium-deep geothermal resources in the oil and gas sector [1] - The extraction of high-temperature liquid from underground during oil production provides a usable heat resource, which can be harnessed through heat exchange technology for oil heating and insulation, thus preventing pipeline blockage due to low temperatures [1] Group 2: Strategic Development and Future Plans - The Shengli Oilfield is located in the Jiyang Depression, characterized by a geological structure of "oil basin + heat basin," and has established a development strategy for 2024 focusing on "building geothermal fields within oilfields" [1] - The company plans to convert idle oil wells into geothermal wells and utilize extracted heat to replace gas heating in oilfield transportation systems, while also promoting the interconnection of heating networks with local enterprises to drive green transformation in the surrounding areas [1][2] - A total of 51 geothermal heat recovery projects have been established, providing an annual clean heating capacity of 3.46 million GJ and reducing CO2 emissions by 22,300 tons [1]

Core Insights - Sinopec's Shengli Oilfield has successfully completed an energy transformation project that utilizes geothermal resources for heating, marking significant progress in the industrial application of medium and deep geothermal resources in China's oil and gas sector [1][2]. Group 1: Project Details - The 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 efficient utilization of clean thermal energy [1]. - The annual clean heating capacity of the project is estimated at 209,000 gigajoules, with heating costs reduced by 59%, replacing 6.38 million cubic meters of natural gas, which can meet the annual gas needs of approximately 20,000 urban households [1]. - The project contributes to a reduction of 13,500 tons of carbon dioxide emissions annually [1]. Group 2: Strategic Shift - Shengli Oilfield is accelerating its transformation from a traditional oil and gas production company to a diversified green energy supplier [1]. - The Jiyang Depression has a total geothermal resource equivalent to about 25 billion tons of standard coal, with an average geothermal gradient of 3.4 to 4.2 degrees Celsius per 100 meters, representing a typical geological structure of "oil basin + thermal basin" [1]. - The oilfield has established 51 geothermal waste heat utilization projects and revitalized 25 abandoned wells, achieving an annual clean heating capacity of 3.46 million gigajoules [1]. Group 3: Industry Implications - The practice of converting abandoned wells into heat source wells and developing new thermal fields in old oil fields provides a replicable and scalable model for the clean transformation of the traditional oil and gas industry [2]. - This approach is significant for achieving new energy integration in the oil and gas sector and promoting adjustments in the national energy structure [2].
