摘　　要：布参1井峨眉山玄武岩组纵向裂隙发育,自井深717m开始至井深1969m下入技术套管为止,施工期间出现不同程度的漏失,漏失程度为中等——失返性漏失。采用随钻堵漏、水泥浆堵漏、桥接材料堵漏、顶漏强钻等工艺进行处理,确保了该井顺利施工完钻,为今后钻遇类似地层制定施工方案提供基础数据。Longitudinal fissures are well developed in the Emeishan basalt of the borehole Bucan-1.Total lost circulation occurred in the borehole depth of 717-1969 m.Lost circulation control while drilling,loss circulation control by cementing and bridging material plugging and top leakage drilling were used which ensured the smooth construction of the borehole.
