As the development of unconventional oil and gas resources continues, fracturing technology has become a crucial method for enhancing reservoir productivity. However, optimizing fracturing parameters and identifying the key factors that control productivity, along with understanding their mechanisms, remain significant challenges. This paper proposes a novel approach that combines construction curve feature extraction with a hybrid optimization model to improve the effectiveness of fracturing parameter optimization. Initially, key features closely related to productivity were extracted from construction curves, and a comprehensive correlation coefficient method was employed to identify the primary factors influencing open flow capacity. Subsequently, the SSA-BP (Salp Swarm Algorithm-Back Propagation) hybrid optimization model was used to model these selected features, and a genetic algorithm was applied for systematic optimization of fracturing parameters. To validate the proposed method, a field application test was conducted on Well A-X in the A Gas Field of the Tarim Basin. Following the initial fracturing operation, adjustments to the fracturing parameters were made based on feedback from the model, and a refracturing operation was performed. The results indicated a significant increase in daily gas production and a substantial improvement in open flow capacity for Well A-X, confirming the effectiveness and practical value of the proposed method in enhancing post-fracturing productivity. This study contributes a novel framework integrating feature extraction and hybrid optimization, offering a flexible tool for parameter design in low-permeability gas reservoirs.
