In order to find out the lithology， sedimentary facies， thickness of organic rich effective mud （shale） and gas bearing property of the lower Carboniferous Luzhai formation in the Luorong favorable area in the east of Liuzhou， and obtain the relevant parameters of shale gas in the organic rich mud shale section， the Department of Land and Resources of Guangxi Zhuang Autonomous Region deployed a small-diameter geological survey well—Well Guiliudi-1 in Guizhong depression. With use of HXY-8B core drill and the multiple-section vertical drilling method， the well was drilled layer by layer； the pilot type reaming tool， together with the PVA1788 solid free flushing fluid system was used to ream the hole step by step with the casing set tier by tier， meanwhile， geological logging， electrical logging， cementing and drilling evaluation was carried out； which solved the drilling difficulties in deep mud stone， such as difficult coring， poor wellbore stability， over curvature of the borehole. The drilling technology can provide useful experience for shale drilling in the Carboniferous Luzhai formation in the area.
