Hydraulic fracturing, as the core technology for commercial development of unconventional oil and gas reservoirs, directly impacts the resource development benefits. Although current fracturing technology has supported the 400×108 m³ production capacity in southern Sichuan shale gas, increasing shale gas production in southern Sichuan is facing a series of challenges as development progresses. To address the challenges faced by fracturing technology in the large-scale development of southern Sichuan shale gas—including inadequate timely on-site technical support for well pads, over-reliance on personal experience in fracturing design and construction, insufficient risk prediction, difficulties in sharing technical experience, low integration level, lack of achievement sharing, and limited application of digital information technology—this paper explores the development of an integrated geo-engineering intelligent fracturing system. Based on the full-chain collaborative model of “research-design-construction-effect evaluation”, the system establishes a collaborative research platform, integrates multi-source data, and realizes data management and achievement sharing. It optimizes intelligent fracturing design, develops process-oriented tools, and improves modeling and design efficiency. It strengthens intelligent fracturing implementation, achieving real-time on-site control through modules such as diagnostic early warning and fracture monitoring. Furthermore, it improves intelligent post-fracturing evaluation, simplifies simulation processes, and conducts batch simulation of multiple schemes. As a key technical link in the intelligent construction of southern Sichuan shale gas fields, the integrated geo-engineering intelligent fracturing system will drive the transformation and upgrading of the fracturing process from digitization to intelligence. It will further enhance the development benefits of southern Sichuan shale gas.
