Abstract: Purpose: This study aims to address the challenge of efficiently connecting new platforms to existing gathering and transmission pipeline networks during the stable production phase of the Changning Shale Gas Field. It focuses on overcoming terrain constraints and ensuring compatibility between new and existing systems to support sustainable gas field development. Methods: A shale gas mixing process optimization scheme was proposed, emphasizing terrain adaptability and system compatibility. The approach implemented a centralized measurement and processing technical route for short-distance mixed transportation. Results: A pilot project completed in July 2024 successfully validated the feasibility of this technical route. Practice demonstrated that the scheme not only effectively adapts to complex terrain but also exhibits significant advantages in reducing investment, optimizing management, and improving operational efficiency. Conclusion: This study provides an engineering paradigm integrating terrain adaptability, operational economy, and process compatibility for pipeline network expansion during the stable production phase of the Changning and similar shale gas fields. It offers valuable insights for promoting efficient development in such contexts.
