AB  - Addressing the complexity of quality evaluation during the R&D phase of the waterflooding sandstone reservoir numerical simulator (OSIM), this study establishes a comprehensive assessment framework driven by client-side requirements. The novelty of this work lies in the integration of a client-driven 146-indicator hierarchy specifically tailored for iterative simulator R&D. First, a hierarchical software quality evaluation model is constructed, encompassing four primary dimensions and 146 secondary indicators. To mitigate the subjectivity inherent in traditional weight assignment, the Fuzzy Best-Worst Method (FBWM) is employed to determine indicator weights. Subsequently, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is integrated to develop a composite ranking algorithm, coupled with specific protocols for acquiring indicator values were established using an 80-case model library. Finally, the proposed framework is validated using nine iterative versions of OSIM and the Commercial Software (CS). Results indicate that the final OSIM version achieved a superior overall ranking with a composite score of 0.962, surpassing the Commercial Software’s score of 0.944, verifying the effectiveness of the method. The Root Mean Square Error (RMSE) for field water cut was controlled within 1.8%, demonstrating high simulation precision. This methodology exhibits strong universality, offering a scientific reference for the quality assessment of various reservoir simulators, including thermal and chemical flooding.
