| Abstract |
Following the 2023 World Geothermal Congress, Sinopec Green Energy (SGE) has achieved groundbreaking advancements in geothermal exploitation. The company innovatively implemented stratified extraction and downhole collision-avoidance technologies, establishing a multi-well collaborative "well factory" development model in confined spaces. Pioneering the world's first heat-electricity-helium tri-generation system, SGE successfully integrated geothermal power generation with helium extraction, enabling synergistic development of water, thermal, and mineral resources. To address spatial mismatch between geothermal resources and urban planning, a long-distance integrated collection-transport-reinjection system was developed, achieving large-scale resource distribution, centralized reinjection, and dynamic stabilization of reservoir temperature-pressure fields. Concurrently, an intelligent management platform was constructed by integrating instrument data acquisition, network communication, and digital twin technologies, forming a smart control system with load prediction and logical regulation capabilities. This integrated technological framework has realized sustainable development objectives of extraction-reinjection equilibrium, thermoelectric coordination, and multi-energy complementarity, providing replicable Chinese solutions for global geothermal industry advancement. The innovations demonstrate significant improvements in resource utilization efficiency and set benchmarks for ecological conservation. |
