Abstract Hydraulic fracturing technology, as an effective means to increase single well production, has been widely used in the production of various types of oil and gas reservoirs, achieving significant production enhancement. However, the heterogeneity of reservoirs determines that different reservoirs with different characteristics require different fracturing parameters. Using the same construction parameters for different reservoirs may increase operational costs and have adverse effects on production. In order to accurately obtain the optimal fracturing scheme, this study focuses on the following four aspects: 1) Regional geological research to accurately characterize the geological features of the reservoir; 2) Simulation research on the three-dimensional propagation of artificial fractures to visualize the artificial fracture network formed by different construction scales in three-dimensional space; 3) Numerical simulation research on productivity, combining the results of fracturing simulation to predict post-fracturing productivity; 4) Comparison and optimization of different fracturing schemes, considering factors such as fracturing construction cost, post-fracturing productivity, and effectiveness. The research results provide technical support for the design and optimization of fracturing schemes for production wells.
