In order to evaluate the gas bearing property of shale around Xuefeng Ancient Land， Well Xiangtaodi-1， a shale gas geological survey well， was constructed in Yuanma Basin in 2019. The completed drilling depth was 1850.88m. the whole well was cored， and the average core recovery rate was 97.24%. XY-8 drilling rig is used in the construction， which adopts third spud hole structure， cooperate with gas logging and comprehensive geophysical logging technology， and optimizes the BHA， bit， drilling parameters and drilling fluid performance. Due to the instability and block falling of the carbonaceous mudstone in Niutitang Formation and the untimely adjustment of the drilling process， the downhole complications such as drill rod sticking， drill rod burying and drill tool breaking occurred. The screw motor sidetracking is adopted to bypass the obstacles， so as to solve the downhole problems such as sticking and burying. After sidetracking， continue to drill 806.87m with the same diameter until the completion of drilling. The successful completion of the well and the complex downhole treatment methods provide reference experience for the construction of geological survey wells in similar areas.
