Abstract: After nearly 20 years of exploration, significant breakthroughs have been made in the development of low-permeability gas reservoirs in the East China Sea, and relevant development technologies have gradually matured. A preliminary technical system tailored to the characteristics of low-permeability gas reservoirs in the Xihu Sag has been established, and the core driving force for transforming difficult-to-produce resources into economically viable production has been revealed. However, the large-scale development of these reservoirs in the East China Sea still faces three major scientific and technological challenges: deepening theoretical understanding, overcoming key technical barriers, and achieving cost-effective and efficient development. To address these issues, future research and development efforts should focus on the following three aspects: (1) strengthening fundamental research to deepen theoretical understanding and establish a high-success-rate system for reservoir evaluation and selection; (2) overcoming key technical barriers by developing more adaptable technologies and equipment systems for the development of low-permeability gas fields in offshore areas; (3) improving development efficiency through establishing an integrated technical and management model that supports low-cost and efficient development of low-permeability gas reservoirs in offshore areas, encompassing offshore engineering, drilling, gas production, and transportation.

Key words: East China Sea, Xihu Sag, low-permeability gas reservoirs, development practices, offshore oil and gas, hydraulic fracturing
