Abstract: To enhance the development efficiency of deep shale gas in the Qiongzhusi Formation of Ziyang, a series of acceleration technologies were studied, significantly improving drilling performance. Research on casing point optimization based on trip intervals and the "1+N" principle enabled dynamic well structure adjustment. The minimum curvature method was prioritized in trajectory design to reduce footage, establishing a speed-enhancing wellpath methodology. In vertical sections, pre-bent bottom hole assemblies were introduced alongside dynamic models to strengthen deviation control, achieving both verticality maintenance and faster drilling. For challenging formations, customized PDC bits were developed through rock drillability experiments and rock-breaking mechanism analysis, yielding an 18.75% rate of penetration (ROP) increase. In lateral sections, the integrated "four-in-one" steering technique combined with oil-based drilling fluid balanced collapse pressure to extend wellbore stability, while rotary steerable systems (RSS) and positive displacement motors (PDM) enabled single-run drilling. Field applications across 16 wells demonstrated an average ROP increase from 5.78 m/h to 7.74 m/h (33.9% improvement) and a reduction in average drilling cycle from 122.83 days to 101.33 days (17.5% reduction). These results confirm that core technological breakthroughs—including dynamic well structure optimization, high-efficiency trajectory design, and physics-based cutting-limit bit development for hard formations—effectively ensured drilling safety and efficiency. This comprehensive approach provides robust technical support for deep shale gas development.
