摘　　要：广西柳城区块鹿寨组发育一套厚层页岩,具备较好的页岩气勘探开发潜力。实钻资料表明,该区地质、测井曲线特征与四川盆地存在较大差异性,伽马曲线整体呈齿化块状中高值,缺少稳定可靠的地层对比标志点,导致在涪陵页岩气田应用效果良好的水平井地质导向方法难以适应柳城区块的地质特征,为解决该技术难点,提出趋势导向法,将其应用于桂融页2-1井地质导向工作,效果良好。The Luzhai Formation in the Liucheng block of Guangxi hosts a thick shale layer with significant potential for shale gas exploration and development.Drilling data indicate substantial differences in geological and logging curve characteristics compared to the Sichuan Basin,with gamma curves showing serrated blocky medium-to-high values and lacking stable stratigraphic markers.This renders the geological steering methods effective in Fuling shale gas field less applicable here.To address this challenge,the trend-oriented method was proposed and successfully applied in the geological steering of Well Guirong 2-1,achieving favorable results.
