The paper introduces the general situation of Well Xiangdongdi-1 for basic geological survey of shale gas, describes emphatically the drilling construction techniques and process. Combined with the actual drilling strata and well logging data, the drilling construction quality is analyzed and summarized. In view of the problems in the drilling process, the improvement measures are put forward and remarkable effects have been achieved. Diamond wire-line core drilling technology is adopted in Well Xiangdongdi-1, by the prediction of common accidents in this technology and strong whipstocking stratum, construction methods are optimized and mid-term construction quality is strictly controlled to effectively prevent downhole accidents and improve the driller-month efficiency. 6 indicators of drilling quality meet the geological requirements, drilling construction is smoothly completed.
