The Xuefengshan pilot hole is a shale gas geological survey hole deployed in the Mayang syncline in the Yuanma Basin in Western Hunan. This paper introduces the engineering and geological conditions of the borehole with focus on the drilling and completion technology. The complex formations and drilling technical difficulties encountered during the drilling process are also summarized and analyzed with specific solutions put forward for different drilling difficulties. The solutions mainly include improving drilling and coring tools， adopts wire-line coreing tool that does not lift the drill to replace the inner drill bit with a spring core protector cord. Micro-foam drilling fluid and a drilling fluid formula of bentonite+lignite resin+broad-spectrum wall protectant type III+high temperature and salt resistance fluid loss agent+limestone powder are used. Developing the relevant management measures. As a result， drilling efficiency has been improved， drilling quality has met the geological requirements， and the drilling tasks have been effectively completed. It is desired the drilling experiences can provide technical reference for drilling of similar shale gas survey boreholes.
