Progress in large-scale green heat industrial application in Shengli Oilfield, China

Recently, the East No.1 Combined Station of Gudong Oil Production Plant in Shengli Oilfield, Sinopec, has completed its energy transformation, successfully replacing traditional gas heating with waste heat from produced fluids extracted from a depth of 3,200 meters underground. It is expected to achieve an annual clean heating capacity of 209,000 GJ, replacing 6.38 million cubic meters of natural gas and reducing carbon dioxide emissions by 13,500 tons annually. The first medium-deep geothermal project for oil and gas production in Shandong Province, built by Gudao Oil Production Plant, has also been put into operation recently, with an annual clean heating capacity of 75,000 GJ. This marks positive progress in the large-scale industrial application of medium-deep geothermal resources in China's oil and gas sector.

During the extraction of crude oil, some high-temperature aqueous liquids are extracted from the underground. These produced fluids are also excellent sources of waste heat that can be utilized. In the crude oil production process, the waste heat in these produced fluids can be extracted through relevant heat exchange technology and used for heating and insulation of crude oil, preventing it from condensing and blocking pipelines due to excessively low temperature. This can replace the traditional gas heating method, achieving clean heating and reducing costs.

The Jiyang Depression, a crucial exploration and development area of Shengli Oilfield, is a typical geological structure featuring an "oil basin + thermal basin". In 2024, Shengli Oilfield established the development strategy of "building a thermal field within the oil field". By transforming idle oil wells into geothermal wells and extracting waste heat from produced fluids, clean thermal energy is used to replace gas heating furnaces in the oilfield gathering and transportation system for heat supply. At the same time, it promotes the interconnection and interworking of heating pipelines with local enterprises, driving the green transformation of the surrounding areas. Currently, 51 geothermal waste heat utilization projects have been established, with an annual clean heating capacity of 3.46 million gigajoules and a potential reduction of 223,000 tons of carbon dioxide emissions.
