摘　　要：Aiming at the problems of deep shale gas wells in Baima Block of Fuling Shale Gas Field, such as deep burial, complicated geological structure, frequent leakage, low penetration rate and low cementing quality rate, the difficulties in drilling and completion of deep shale gas in Baima Block are summarized based on the analysis of the geological characteristics of the block and the previous drilling and completion data. Through the technical research of differential wellbore structure optimization, sectional wellbore trajectory control, personalized PDC bit design, anti-high temperature leak-proof and plugging drilling fluid technology and narrow safety window cementing technology, A set of fast drilling and completion technology suitable for deep shale gas in Baima Block has been formed and applied in this block for 15 wells, with the average penetration rate increased by 41.95% year on year, the drilling cycle shortened by 30.40%, and the cementing quality rate increased by 10%. The application effect is good. The technology can be popularized and applied as fast drilling and completion technology for deep shale gas in Baima Block.
