| Abstract: | In order to increase drilling speed in the East Sichuan area and speed up ltS exploration progress, the upper continental formations of Well Laojun-1 located at the Laojunshan structure are tested by air drilling technology and make success. The 2 491.70 m length of hole section is finished after 21 days with an average ROP of 11.27 m/h that is 10 times higher than conventional drilling, which provides new technical options for further drilling in this area. Feasibilities of air drilling at such condition are analyzed in terms of wellbore wall stability, formation pressure, and formation outputs. In addition, this paper presents the air drilling process, equipment, detail operations, as well as technical considerations and urgent problems arised from air drilling. |
