摘要
Based on the DP31H well in Daniudi gas field of Ordos basin,which is a horizontal well with 2000m super-long radius,the difficulties in each section construction are analyzed with the countermeasures.In the drilling process,fast drilling and borehole curvature in the second section with 311.2mm;bit selection,cutting bed and back pressure in the third super-long horizontal construction were encountered.By the rational technical measures,the construction was successfully finished.
