In the context of the deep penetration of digital technology, sci-tech journals, as the core carrier of academic communication, face difficulties in meeting the needs of scientific research dissemination through their traditional models. Under this trend, sci-tech journals actively engage in new media practices, and innovative communication based on the WeChat ecosystem has become a key path for the transformation of sci-tech journals. Based on the practice of journals such as Petroleum Reservoir Evaluation and Development, this article systematically explores the collaborative mechanism between content operation and live streaming practice, providing theoretical and practical references for sci-tech journals to achieve the transformation of "ecological co-construction".

The article adopts a case study method to focus on the new media communication practices of sci-tech journals in the WeChat ecosystem. Firstly, it combs the multi-dimensional value of WeChat official account content operation and WeChat video live streaming in the new media communication of sci-tech journals. Secondly, it integrates practical experience and proposes a collaborative operation strategy for the new media matrix of sci-tech journals to maximize communication efficiency. Finally, in response to the current multiple reality challenges, a corresponding deepening path is constructed.

The research shows that sci-tech journals can significantly improve their communication efficiency by using WeChat official account, which is mainly reflected in three dimensions: timeliness breakthrough, interactive reconstruction, and user profile construction, which is conducive to achieving the leap in academic communication efficiency of sci-tech journals, and reconstructing the interactive relationship between sci-tech journals and users. Secondly, WeChat video live streaming opens up a new track for enhancing the influence of sci-tech journals from four aspects: academic influence diffusion, communication dimension expansion, communication chain extension, and brand scenario shaping, through its real-time images, online interaction, and multi-platform synchronization.

Research suggests that in order to maximize the new media communication efficiency of sci-tech journals, a collaborative operation framework of "thinking transformation–content innovation–precise distribution–interactive deepening–technology empowerment" should be constructed to promote the collaborative operation of the new media matrix in sci-tech journals. In the face of insufficient supply of composite talents, the balance between technological empowerment and cost control, the collaborative dilemma between user growth and content quality control, and the new challenges of copyright protection, the deepening and upgrading can be achieved by building an "editing–operation–technology" collaborative mechanism, promoting "low-cost–high-adaptation" technology application solutions, establishing an "academic value–dissemination efficiency" evaluation system, and building an industry joint copyright protection platform.
