As key equipment in oil and gas transmission systems, multiphase pumps are crucial for ensuring a closed oilfield collection and transmission. The booster unit, as the core component of the multiphase pump, has blade shapes that significantly impact the pump efficiency and its gas-liquid mixing performance. To enhance the efficiency of the booster unit and improve its gas-liquid mixing, this study first adopts the optimal Latin hypercube design sampling technique for the blade shape parameters and establishes a library of design samples. Subsequently, the effects of various blade shape parameters on the pump efficiency and gas-phase distribution were systematically investigated. An approximate prediction model was developed to predict the performance and was integrated into a multi-objective optimization framework to identify Pareto-optimal blade configurations. The results show that after optimization, the efficiency of the pump increased from 52.60% to 54.56%, a 3.59% improvement, and the gas uniformity at the impeller outlet was reduced from 0.3229 to 0.3040, a 6.22% reduction. A comparative analysis of the internal and external characteristics confirmed the improved gas dispersion and refined flow field structures within the optimized booster unit. The proposed methodology provides a systematic and efficient strategy for the performance-driven design of multiphase pump blades by integrating advanced sampling, modeling, and optimization techniques.
