By taking examples of drilled shale gas horizontal well PY-X1 and impending geosteering drilling well PY-X2 in some region of Southeast Sichuan, this paper initially discussed three key issues in geosteering drilling of shale gas horizontal wells, such as the azimuthal correction, apparent dip determination of the well trajectory direction, and the trace control in target window, and initially gave the corresponding solution and suggestion combined with the actual situation of the geosteering.
