The Weiyuan Area of the Sichuan Basin has a significant amount of deep shale gas that has a high potential for development. However, challenges arise due to differences in in-situ stress, strong heterogeneity, micro-structure, and natural fracture development. These challenges result in issues such as a simple fracture network, significant discrepancies in post-fracturing evaluation, and frac hits during the pre-fracturing process. To enhance the effectiveness of shale gas development, a fracturing design concept called “fully communicate, globally support, and remotely diversion” has been implemented. This concept emphasises the integration of geological and engineering technology ideas. As a result, a new generation of shale fracture-controlled fracturing technologies has been developed. These include 1 + n differentiated design, composite temporary plugging technology, and casing prevention. The research findings indicate that: (1) implementing the 1 + n differentiated design, which includes long-stage and multi-cluster features, fluid-volume control, improved sand-ratio, and promoted uniformity in composite temporary plugging, leads to a 75% increase in sand addition intensity compared to the previous fracking stage. Additionally, the average post-pressure test production of a single well increases by 12%, and the average EUR (Estimated Ultimate Recovery) of a single well increases by 34%; (2) the application of composite temporary plugging technology significantly enhances the pressure rise in the same displacement compared to the previous stage. Furthermore, well testing of the post-pressure production demonstrates that the section cluster modification has reached 98.57%. In recent years, a total of 16 wells with 264 sections have been successfully executed, resulting in no casing deformation or segment loss. The prevention and control of set change has shown exceptional effectiveness. In the practice of deep shale gas fracturing in the Weiyuan Area, the team has focused on enhancing core technology research and developed the concept of “one well for one strategy, one method for one section”. This approach involves carefully stimulating high-quality well sections and moderately stimulating risky well sections. As a result, the effectiveness of the transformation has consistently improved. The team has also created and refined multiple sets of templates for deep shale gas.
